Indo-Islamic Architecture: Sultanate and Mughal Styles
Complete notes on Indo-Islamic architecture for competitive exams: the arcuate style, Delhi Sultanate and provincial schools, and Mughal monuments with builders.
By GK24 Editorial Team· Published · 4 min read

Indo-Islamic architecture is the building style that grew in India after the Turkish conquests of the late twelfth century, when the arch, the dome and the minaret of West Asia were raised by Indian masons out of Indian stone. Examiners return to it every year because each monument carries three facts that fit in one line: who built it, where it stands, and what was new about it. These notes take the style from the first mosques of Delhi to the marble of the Mughals.
What made the style new
Older Indian building was trabeate: weight rested on pillars and beams, and a dome shaped roof was made by laying stones one over another, a method called corbelling. The new style was arcuate: a true arch carried the load sideways into its supports, and a true dome stood on that arch. Lime mortar as a cementing material spread with it. Since the image of a living being was avoided in religious building, ornament turned to calligraphy in Arabic script, arabesque or stylised plant forms, geometric patterns and jali screens of pierced stone. The earliest mosques were raised from the material of demolished temples, so Indian carving and Islamic form stand side by side at the Quwwat-ul-Islam mosque in Delhi and at Adhai Din ka Jhonpra in Ajmer.
The Delhi Sultanate: the Imperial style
The Slave or Mamluk period began the work. Qutb-ud-din Aibak built the Quwwat-ul-Islam mosque and began the Qutub Minar, a victory tower of about 73 metres that Iltutmish carried up and Firoz Shah Tughlaq repaired. Iltutmish also built his own tomb, the first Sultanate tomb in Delhi. Under the Khaljis the true arch and the true dome arrived together in the Alai Darwaza, the southern gateway added by Alauddin Khalji in 1311, built of red sandstone inlaid with marble. Tughlaq building is the plainest of all: grey sandstone, thick sloping or battered walls, minimum ornament and a fortress look, seen at Tughlaqabad and at Firoz Shah Kotla. The Lodis gave India the double dome, an outer shell for height and an inner one for a usable ceiling, and the octagonal and square garden tombs now standing in Lodi Gardens.
Provincial schools
When the Sultanate weakened, the provinces built in their own way.
| School | Place | Known for |
|---|---|---|
| Jaunpur (Sharqi) | Jaunpur, Uttar Pradesh | Atala Masjid, with a huge propylon screen and no minarets |
| Gujarat | Ahmedabad | Sidi Sayyid mosque and its tree of life jali; Jama Masjid of Ahmedabad |
| Bengal | Pandua and Gaur | Adina Masjid, brick work, curved bangla roof |
| Malwa | Mandu | Jahaz Mahal, Hindola Mahal, Rani Roopmati pavilion, Hoshang Shah tomb in marble |
| Bijapur (Adil Shahi) | Bijapur, Karnataka | Gol Gumbaz, the tomb of Muhammad Adil Shah, with its whispering gallery |
| Golconda (Qutb Shahi) | Hyderabad | Charminar and the Golconda fort |
Mughal architecture
Babur left little, and Sher Shah Suri filled the gap with the Purana Qila in Delhi and his own tomb at Sasaram, set in a lake. The Mughal line proper begins with Humayun tomb in Delhi, raised by his widow Hamida Banu Begum and designed by Mirak Mirza Ghiyas: the first garden tomb in India, a charbagh divided by water channels, and the model that leads to the Taj.
Akbar built in red sandstone. His capital at Fatehpur Sikri holds the Diwan-i-Khas with its central pillar, the Panch Mahal, the Jodha Bai palace and the Buland Darwaza, raised in 1575 to mark his Gujarat victory and among the tallest gateways anywhere. He also built the forts of Agra, Lahore and Allahabad. Jahangir preferred gardens: the Shalimar Bagh of Srinagar is his, and in his reign Nur Jahan built the tomb of her father Itmad-ud-Daulah at Agra, the first Mughal building faced wholly in white marble and the first to use pietra dura, the inlay of coloured stone.
Shah Jahan is the marble age: the Taj Mahal at Agra for Mumtaz Mahal, with Ustad Ahmad Lahauri named as its architect, the Red Fort and the Jama Masjid of Delhi, the Moti Masjid in Agra Fort and the new city of Shahjahanabad. Aurangzeb built little of beauty: the Bibi ka Maqbara at Aurangabad, a smaller copy of the Taj, and the Badshahi mosque at Lahore. After him the style thins into the Lodi like tombs of the later eighteenth century, such as Safdarjung tomb in Delhi.
Words that carry marks
- Charbagh: a garden in four quarters, split by walkways or water.
- Pietra dura: coloured stones cut and set into marble to make a design.
- Jali: a pierced stone screen that lets in light and air.
- Iwan: a deep vaulted hall open on one side, usually the entrance.
- Chhatri: a domed kiosk on pillars, borrowed from Rajput building.
Exam Point of View
Examiners ask four kinds of questions here. First, monument against builder: Quwwat-ul-Islam and Qutub Minar with Aibak, Alai Darwaza with Alauddin Khalji, Jama Masjid of Delhi and the Taj with Shah Jahan, Shalimar Bagh with Jahangir. Second, the first of its kind: the first true arch and dome, the first garden tomb, the first marble building with pietra dura, the first double dome. Third, monument against place: Gol Gumbaz at Bijapur in Karnataka, Sidi Sayyid mosque at Ahmedabad, Atala Masjid at Jaunpur, Jahaz Mahal at Mandu. Fourth, terms: charbagh, pietra dura, jali, iwan, chhatri, arabesque. Common traps are pairing the Jama Masjid of Delhi with Akbar, calling the Taj the first marble building, and placing Gol Gumbaz in Telangana because of the Charminar.

Practice MCQs on this topic
In which state is Gol Gumbaz, the tomb of Adil Shah, situated?
- A.Karnataka
- B.Tamil Nadu
- C.Kerala
- D.Telangana
Show answer
Correct answer: A. Karnataka
Explanation
The correct answer is A, Karnataka. The Gol Gumbaz stands at Bijapur, now called Vijayapura, in Karnataka. It is the tomb of Muhammad Adil Shah of the Adil Shahi dynasty of Bijapur and was completed in the middle of the seventeenth century. Its dome is one of the largest masonry domes in the world and rests on interlocking arches without any supporting pillars inside, leaving a single vast chamber. The gallery running around the base of the dome is famous as the whispering gallery, where a low sound is repeated several times.
Option B, Tamil Nadu, is the land of Dravida temple building, not of the Deccan sultanates. Option C, Kerala, has its own timber and tiled roof tradition. Option D, Telangana, does hold Qutb Shahi work such as the Charminar and the Golconda fort, but the Adil Shahi capital was Bijapur in Karnataka, so D is the trap option here.
Jama Masjid of Delhi was built by?
- A.Akbar
- B.Humayun
- C.Babar
- D.Shah Jahan
Show answer
Correct answer: D. Shah Jahan
Explanation
The correct answer is D, Shah Jahan. The Jama Masjid of Delhi, whose formal name is Masjid-i-Jahan-Numa, was built by Shah Jahan between 1650 and 1656 as the congregational mosque of his new capital Shahjahanabad. It is built of red sandstone and white marble, stands on a high plinth reached by broad flights of steps, and has two tall minarets and three domes. It is among the largest mosques in India.
Option A, Akbar, built in red sandstone at Fatehpur Sikri and Agra, but the Delhi Jama Masjid belongs to his grandson. Option B, Humayun, built the short lived Dinpanah and is remembered instead through the garden tomb raised for him after his death. Option C, Babur, ruled only from 1526 to 1530 and left very little building in India. The Jama Masjid belongs firmly to the marble and sandstone age of Shah Jahan, who also raised the Taj Mahal and the Red Fort.
What is the approximate height (in metres) of the Qutub Minar situated in Delhi?
- A.75
- B.77
- C.73
- D.71
Show answer
Correct answer: C. 73
Explanation
The correct answer is C, 73. The Qutub Minar in Mehrauli, Delhi, rises to about 72.5 metres, which is taken as 73 metres in answer keys. It is the tallest brick minaret of its kind, tapering from a base diameter of roughly 14.3 metres to about 2.7 metres at the top, and it is climbed inside by a spiral staircase of around 379 steps. Qutb-ud-din Aibak began it, Iltutmish added storeys, and Firoz Shah Tughlaq repaired the upper part after lightning damage, which is why the material changes from red sandstone below to marble and sandstone above.
Options A, B and D give 75, 77 and 71 metres. All three are near misses put there to test whether the figure has been memorised rather than guessed. Examiners like this monument because it also carries the Iron Pillar of Delhi in the same complex, along with the Quwwat-ul-Islam mosque and the Alai Darwaza.
In which year did Emperor Akbar build the Buland Darwaja?
- A.1502
- B.1526
- C.1534
- D.1575
Show answer
Correct answer: D. 1575
Explanation
The correct answer is D, 1575. The Buland Darwaza, the lofty gateway on the south side of the Jama Masjid at Fatehpur Sikri, was raised by Akbar in 1575 to mark his conquest of Gujarat. It is built of red sandstone with white and black marble inlay, stands about 54 metres above the ground and is reached by a long flight of steps, which makes it one of the tallest gateways in the world. An inscription on it carries the saying that the world is a bridge, to be passed over and not built upon.
Option A, 1502, falls before the Mughals reached India at all. Option B, 1526, is the year of the first battle of Panipat, when Babur defeated Ibrahim Lodi, so it belongs to the founding of the empire, not to Akbar. Option C, 1534, falls in the reign of Humayun. Only 1575 fits Akbar and the Gujarat campaign.
The famous Shalimar Bagh of Srinagar was built during the reign of __________.
- A.Azam Shah
- B.Akbar
- C.Humayun
- D.Jahangir
Show answer
Correct answer: D. Jahangir
Explanation
The correct answer is D, Jahangir. The Shalimar Bagh on the bank of the Dal lake in Srinagar was laid out by Jahangir in 1619 for his queen Nur Jahan. It is a Mughal garden in the charbagh plan, built in rising terraces fed by a central water channel, with pavilions and cascades, and it shows how far the Mughals carried the Persian idea of a garden as a picture of paradise. Jahangir loved Kashmir and the Nishat Bagh nearby belongs to the same period.
Option A, Azam Shah, was a son of Aurangzeb and is linked with the Bibi ka Maqbara at Aurangabad, not with Kashmir. Option B, Akbar, annexed Kashmir in 1586 and built the Hari Parbat fort wall there, but not this garden. Option C, Humayun, spent his reign in war and exile and left no garden of this kind. The Shalimar Bagh belongs to Jahangir.
The Alai Darwaza, the first building in India to use a true arch and a true dome, was built by:
- A.Iltutmish
- B.Alauddin Khalji
- C.Firoz Shah Tughlaq
- D.Sikandar Lodi
Show answer
Correct answer: B. Alauddin Khalji
Explanation
The correct answer is B, Alauddin Khalji. The Alai Darwaza was added in 1311 as the southern gateway to the Quwwat-ul-Islam mosque in the Qutub complex at Delhi. It is the first surviving building in India in which the arch and the dome are true, that is, built of wedge shaped stones that carry the load sideways, instead of being corbelled by laying flat stones one over another. Its red sandstone walls are inlaid with white marble and carry lotus bud fringes on the arches.
Option A, Iltutmish, belongs to the earlier Slave dynasty and built his own tomb and the upper storeys of the Qutub Minar, still in the corbelled manner. Option C, Firoz Shah Tughlaq, came much later and is known for Firozabad, Hauz Khas and the repair of the Qutub Minar. Option D, Sikandar Lodi, is associated with the double dome and with Agra as a capital. Only Alauddin Khalji fits the date and the gateway.
Which monument is regarded as the first garden tomb built on the charbagh plan in India?
- A.Tomb of Sher Shah Suri at Sasaram
- B.Humayun tomb at Delhi
- C.Akbar tomb at Sikandra
- D.Bibi ka Maqbara at Aurangabad
Show answer
Correct answer: B. Humayun tomb at Delhi
Explanation
The correct answer is B, Humayun tomb at Delhi. Built between 1565 and 1572 by his widow Hamida Banu Begum and designed by the Persian architect Mirak Mirza Ghiyas, it is the first tomb in India set in the middle of a charbagh, a square garden cut into four quarters by walkways and water channels. It also brought the high arched entrance, the double dome and the red sandstone with marble facing that the later Mughals repeated. It was the first Indian building of its kind to be placed on the UNESCO World Heritage list in 1993.
Option A, the tomb of Sher Shah Suri, is a magnificent octagonal tomb but it stands on a terrace in the middle of a lake, not a charbagh. Option C, the tomb of Akbar at Sikandra, is later and is indeed in a garden, but it follows Humayun tomb. Option D, the Bibi ka Maqbara, is from the reign of Aurangzeb and is a copy of the Taj.
Which Mughal monument is the first to be faced entirely in white marble and to use pietra dura inlay?
- A.Taj Mahal
- B.Moti Masjid, Agra Fort
- C.Tomb of Itmad-ud-Daulah
- D.Buland Darwaza
Show answer
Correct answer: C. Tomb of Itmad-ud-Daulah
Explanation
The correct answer is C, Tomb of Itmad-ud-Daulah. Nur Jahan built it at Agra between 1622 and 1628 for her father Mirza Ghiyas Beg, who held the title Itmad-ud-Daulah. It is the first Mughal building covered wholly in white marble and the first in which pietra dura, the inlay of cut coloured stones into marble, is used on a large scale. Its small size and delicate finish have earned it the nickname the Baby Taj, because it marks the change from the red sandstone of Akbar to the marble of Shah Jahan.
Option A, the Taj Mahal, carries pietra dura to its highest point but comes later, from 1632. Option B, the Moti Masjid in Agra Fort, is also in marble but belongs to Shah Jahan. Option D, the Buland Darwaza, is of red sandstone with only marble inlay and was built by Akbar in 1575, before the marble phase began.
The Sidi Sayyid mosque, famous for its tree of life stone lattice, is located in:
- A.Ahmedabad
- B.Jaunpur
- C.Mandu
- D.Bidar
Show answer
Correct answer: A. Ahmedabad
Explanation
The correct answer is A, Ahmedabad. The Sidi Sayyid mosque in Ahmedabad, Gujarat, was built in 1573 in the last years of the Gujarat Sultanate. Its half circular windows carry jali screens cut from single slabs of stone, and the finest of them shows a palm and an intertwined creeper, known everywhere as the tree of life. The design has become a symbol of the city and of the Gujarat school of Indo-Islamic building, which is marked by fine stone carving borrowed from local temple craftsmen.
Option B, Jaunpur, is the seat of the Sharqi school, known for the Atala Masjid and its massive entrance screen. Option C, Mandu, is the capital of the Malwa school, known for the Jahaz Mahal and the marble tomb of Hoshang Shah. Option D, Bidar, is linked with the Bahmani sultans and the madrasa of Mahmud Gawan. Only Ahmedabad fits.
Thick sloping or battered walls, grey stone and very plain surfaces are the mark of which dynasty of the Delhi Sultanate?
- A.Slave dynasty
- B.Khalji dynasty
- C.Tughlaq dynasty
- D.Lodi dynasty
Show answer
Correct answer: C. Tughlaq dynasty
Explanation
The correct answer is C, Tughlaq dynasty. Tughlaq building is the most austere phase of the Sultanate style. It uses local grey sandstone or rubble, keeps ornament to a minimum and gives its walls a pronounced batter, that is a slope inward as they rise, which makes even a tomb look like a fort. Tughlaqabad built by Ghiyas-ud-din Tughlaq, his tomb joined to the fort by a causeway, Firoz Shah Kotla and the Hauz Khas complex all show this manner.
Option A, the Slave dynasty, worked in red sandstone with rich carving taken from temple material, as at the Qutub complex. Option B, the Khalji dynasty, brought the true arch and the marble inlay of the Alai Darwaza, which is decorative rather than plain. Option D, the Lodi dynasty, is known for the double dome and for garden tombs on octagonal and square plans, with glazed tile work. The sloping wall belongs to the Tughlaqs.
The Quwwat-ul-Islam mosque, the earliest surviving mosque built by the Delhi Sultanate, was raised by:
- A.Qutb-ud-din Aibak
- B.Balban
- C.Muhammad bin Tughlaq
- D.Ibrahim Lodi
Show answer
Correct answer: A. Qutb-ud-din Aibak
Explanation
The correct answer is A, Qutb-ud-din Aibak. He began the Quwwat-ul-Islam mosque at Delhi in 1192 after the second battle of Tarain, using the carved pillars and stones of temples that stood on the site, which is why its courtyard colonnade carries Indian bells, chains and foliage. Its arched screen was added in front of the prayer hall in the older corbelled manner, since the true arch had not yet arrived. Aibak also began the Qutub Minar beside it.
Option B, Balban, ruled later in the same Slave dynasty and is remembered for his tomb at Mehrauli, which shows an early experiment with the true arch. Option C, Muhammad bin Tughlaq, ruled in the fourteenth century and is known for Jahanpanah and the shifting of the capital to Daulatabad. Option D, Ibrahim Lodi, was the last Sultan of Delhi, defeated at Panipat in 1526. Only Aibak matches the date and the mosque.
Frequently Asked Questions
What is the difference between trabeate and arcuate construction?
Trabeate building carries weight on pillars and horizontal beams, and its domes are corbelled by laying flat stones one over another until they meet. Arcuate building uses a true arch of wedge shaped stones that pushes the load sideways into its supports, and a true dome standing on such arches. Indian temples are trabeate; Indo-Islamic buildings from the Alai Darwaza onwards are arcuate.
Which is the first building in India with a true arch and a true dome?
The Alai Darwaza in the Qutub complex at Delhi, added by Alauddin Khalji in 1311 as the southern gateway of the Quwwat-ul-Islam mosque.
What is a charbagh?
A charbagh is a garden laid out as a square divided into four equal quarters by walkways or water channels, a Persian idea of paradise brought to India by the Mughals. Humayun tomb is the first Indian tomb set in one, and the Taj Mahal follows the same plan.
What is pietra dura and where was it first used in India?
Pietra dura is the craft of cutting coloured stones such as jasper, carnelian and lapis lazuli and setting them into white marble to make flowers and patterns. In India it was first used on a large scale at the tomb of Itmad-ud-Daulah in Agra, built by Nur Jahan between 1622 and 1628, and it reached its height in the Taj Mahal.
Why is the Gol Gumbaz famous?
The Gol Gumbaz at Bijapur in Karnataka is the tomb of Muhammad Adil Shah. Its dome is among the largest masonry domes in the world and rests on interlocking arches with no inner pillars, and the gallery at its base repeats even a whisper, which is why it is called the whispering gallery.
