Indian Architecture III: Indo-Islamic and Colonial Architecture — Sultanate, Provincial, Mughal, Deccani, Rajput Forts and the Raj
Start Here — Where Two Building Traditions Met
🎯 Exam priority: Steady (T2) with heavy Mains overlap with the Mughal articles. UPSC has asked about the building materials at Fatehpur Sikri and Lucknow (2018) and, in Mains, various monuments — Mughal painting and architecture and the Qutub–Humayun–Taj line. The 2016 Mains asked the Indo-Islamic synthesis more than once in different forms.
From the 13th century a new vocabulary — arch, dome, minaret, glazed tile, calligraphy — met the Indian tradition of trabeate construction, carved ornament and the temple craftsmen. The result was Indo-Islamic architecture (the NCERT also uses 'Indo-Saracenic' for the mixture). This article follows the sequence the exam does: Delhi's imperial style; provincial styles; the Deccan; the Mughal phases; forts and gardens; and finally colonial architecture.
Features and Techniques
Trabeate versus arcuate. Indian builders had used brackets, pillars and lintels (trabeate) supporting flat roofs and small shallow domes; arches in wood and stone could not carry the weight above. The newcomers introduced the true arcuate form: arches built of voussoirs (interlocking blocks) with a keystone, domes resting on squinches and pendentives that could span large spaces without pillars. Muslim builders absorbed local elements — bracketed supports, lotus-bud fringes, chhatris and jalis.
Decoration. Since figures were avoided, surfaces carried calligraphy, arabesque, geometric patterns, floral motifs and, later, tessellation and pietra dura (inlaid semi-precious stones) and glazed tiles (blue, turquoise, green, yellow); jali work, trefoil or multi-foliated arches (from the 16th century), lotus-bud fringes in arch curves, a central dome capped by an inverted lotus and a finial.
Materials. Thick rubble-masonry walls clad with chunam plaster or dressed stone: quartzite, sandstone, buff stone and marble; bricks from the 17th century.
Typologies: mosques (including the jama masjid), tombs, dargahs, minars, hammams, formal gardens (charbagh), madrasas, sarais and kos minars (milestones), forts and palaces, and bazaars. Patrons in descending order: rulers and nobles, merchants and guilds, the rural elite, and devotees.
Classification (NCERT): the Imperial style (Delhi Sultanate), the Provincial style (Mandu, Gujarat, Bengal, Jaunpur), the Mughal style (Delhi, Agra, Lahore) and the Deccani style (Bijapur, Golconda).
The Imperial Style — Delhi Sultanate
Dynasty | Monuments | Features |
Slave (Mamluk) | Quwwat-ul-Islam mosque; Qutb Minar (begun by Aibak, extended by Iltutmish and later Firoz Shah); Adhai Din Ka Jhonpra; Sultan Ghari; tomb of Iltutmish | Reuse of temple materials (spoliation); corbelled arches; the Qutb Minar's balconies and inscription bands, ~234 ft and five storeys (per NCERT) |
Khalji | Alai Darwaza (1311); Siri fort; Jamaat Khana mosque; Hauz Khas tank | First true arch and dome of fully Islamic construction in the complex; red sandstone with white marble inlay; the 'lal-gumbad' glazed tile |
Tughlaq | Tughlaqabad fort; Ghiyas-ud-din's tomb; Firozabad (Kotla Firoz Shah) with an Ashokan pillar; Hauz Khas madrasa; Khirki and Kalan mosques | Austere, sloping walls ('batter'), grey stone, strength over ornament |
Sayyid and Lodi | Tombs in Lodi Gardens (Bara Gumbad, Sheesh Gumbad), Sikandar Lodi's tomb, Moth ki Masjid | Octagonal tombs; double dome; garden-tombs, which prepared the ground for Humayun's tomb |
The Qutb Minar is also associated with the Sufi saint Khwaja Qutbuddin Bakhtiyar Kaki. For the Delhi Sultanate's political story, see the two Sultanate articles.
Provincial and Deccani Styles
Province | Examples | Features |
Jaunpur (Sharqi) | Atala Masjid (1408), Jami Masjid | No minarets; massive sloping propylon (gateway) screens; Hindu motifs such as lotus medallions |
Malwa — Mandu | Hoshang Shah's tomb (white marble, jali), Jahaz Mahal, Hindola Mahal, Jama Masjid, Baz Bahadur's palace, Rani Rupmati pavilion | Light, airy buildings suited to the climate; batter walls (Hindola); stepped baolis and reservoirs; colourful stones and marble |
Bengal | Adina Masjid (Pandua), Eklakhi tomb, Gaur monuments | Brick and terracotta; the sloping bangla (do-chala) roof from bamboo huts; stone scarce |
Gujarat | Ahmedabad Jami Masjid, Sarkhej Roza (the white marble dargah of Shaikh Ahmad Khattu), Sidi Saiyyid mosque (jali), Rani ki Vav | Local temple elements — toranas, bell-and-chain motifs, carved trees; the Sarkhej form influenced Mughal tombs |
Kashmir | Shah Hamdan mosque, Jama Masjid, Zain-ul-Abidin's tomb | Wooden structures with pitched roofs |
Mandu is, as the NCERT says, a model of architectural adaptation to the environment: arched pavilions designed to stay cool, built of local stone and marble around two artificial lakes. The Hindola Mahal looks like a viaduct with large buttresses and a sloping 'swinging' wall; the Jahaz Mahal is a two-storey 'ship-palace' between two reservoirs, possibly built by Ghiyas-ud-din Khalji of Malwa.
Sultanate | Monuments | Features |
Bahmani | Jama Masjid, Gulbarga; Madrasa of Mahmud Gawan and Solah Khamba mosque, Bidar; Chand Minar (Daulatabad, 15th c.) | Persian influence — tall arches, enclosed mosque; Chand Minar a 210-ft tapering tower in four storeys |
Bijapur (Adil Shahi) | Gol Gumbaz, Ibrahim Rauza, Jami Masjid | Massive dome and whispering gallery; bulbous domes; dark basalt and plaster |
Golconda (Qutb Shahi) | Golconda fort, Charminar (1591), Qutb Shahi tombs | Concentric walls; Hyderabad's founding |
The Mughal Phases — From Humayun's Tomb to the Taj
Phase | Monuments | Features |
Babur–Humayun–Sher Shah | Mosques at Panipat and Sambhal; Humayun's Tomb (Delhi, 1560s, designed by Mirak Mirza Ghiyas; patron Haji Begam); Purana Qila and Qila-i-Kuhna mosque; Sher Shah's tomb at Sasaram | Persian charbagh, red sandstone with white marble, a double dome — Humayun's tomb is the first garden tomb and the model for the Taj; Sher Shah's tomb is an octagonal, lake-set tomb in an Afghan–Indian style |
Akbar | Agra Fort; Fatehpur Sikri (Buland Darwaza, Jama Masjid, Panch Mahal, Jodha Bai's palace, Diwan-i-Khas, Salim Chishti's tomb); Allahabad and Lahore forts; Akbar's tomb at Sikandra | Red sandstone; fusion of Gujarati, Malwa and Rajput elements; trabeate brackets; chhatris and jalis |
Jahangir | Itimad-ud-Daula's tomb (Agra, by Nur Jahan); Shalimar Bagh (Kashmir); his own tomb at Shahdara (Lahore) | Shift to marble and pietra dura; the first Mughal building fully in marble with inlay |
Shah Jahan | Taj Mahal (1632–53); Red Fort and Jama Masjid, Delhi (Shahjahanabad); Moti Masjid, Agra; Shalimar Bagh, Lahore | White marble, pietra dura, double dome, pishtaq, minarets, symmetric charbagh; Diwan-i-Khas; the Peacock Throne |
Aurangzeb | Badshahi Masjid (Lahore, 1673); Moti Masjid in the Red Fort; Bibi ka Maqbara (Aurangabad) | Austerity, rubble masonry; the decline of royal patronage |
Humayun's Tomb (UNESCO 1993) introduced the monumental charbagh tomb in India, with a high double dome and an arched facade; it was the architectural forerunner of the Taj.
The Taj Mahal (UNESCO 1983) was built from 1632 for about twenty years with some 20,000 specialist workers. NCERT calls it the apogee of the evolutionary process: the plan is orderly and simple, the proportions perfectly symmetrical, the white marble ethereal, the monument placed at the northern end of the charbagh to use the river bank, and the entrance is a monumental red sandstone gateway. The tomb is a visualisation of paradise with Quranic verses, and a statement of imperial grandeur.
Fatehpur Sikri (UNESCO 1986): in 2018 UPSC tested whether the Buland Darwaza and Khankah at Fatehpur Sikri were made of white marble (no — red sandstone), and whether Lucknow's Bara Imambara and Rumi Darwaza used red sandstone and marble (no — brick and lime plaster of the Nawabs of Awadh).
Mughal gardens and sarais: the charbagh plan (four quarters divided by watercourses) in the Shalimar and Nishat gardens of Kashmir and Lahore; sarais ringing the cities, kos minars along the highways, bridges and step-wells.
Forts, palaces and astronomy
Forts symbolised sovereignty: Chittorgarh (the largest fort in Asia; towers of victory, water bodies), Gwalior (which overawed Babur), Daulatabad (staggered gates, twin forts, labyrinth), Golconda (concentric walls). Six Rajasthan hill forts — Chittorgarh, Kumbhalgarh, Ranthambore, Gagron, Amber and Jaisalmer — are UNESCO sites (2013). The Amer Fort's jali work, the Hawa Mahal (1799) and Jaipur's Jantar Mantar (Jai Singh II, UNESCO 2010) show late Rajput–Mughal synthesis; Jaipur (the planned city) became a UNESCO site in 2019.
Colonial Architecture
Group | Examples | Notes |
Portuguese, Dutch, French, Danish | Basilica of Bom Jesus and Se Cathedral (Goa; UNESCO 1986); Dutch Cemetery and fort at Cochin; French Quarter of Pondicherry; Tranquebar's Dansborg | Baroque and Manueline churches; fortified trading posts; Dutch gabled houses |
British — Gothic Revival and neo-classical | St Paul's Cathedral and Victoria Memorial (Kolkata, William Emerson, 1921); Government House; Chhatrapati Shivaji Terminus (Mumbai, F.W. Stevens, 1888; UNESCO 2004); Madras High Court; Writers' Building | Victorian Gothic and neo-classical styles; railway stations, courts, universities |
Indo-Saracenic (Raj-era synthesis of Gothic with Indian elements) | Laxmi Vilas Palace (Baroda, R.F. Chisholm), Mysore Palace (Henry Irwin), Gateway of India (George Wittet, 1924), Victoria Terminus's domes and arches | Domes, chhatris, jalis and arches grafted onto European forms; architects Chisholm, Irwin, Mant, Wittet |
New Delhi | Rashtrapati Bhavan, Secretariat Buildings, India Gate (Edwin Lutyens and Herbert Baker; inaugurated 1931) | A classical plan with Mughal-style gardens and Buddhist chhajja/stupa features |
Modernist India | Chandigarh's Capitol Complex (Le Corbusier, UNESCO 2016), Ahmedabad's institutes (Louis Kahn, Le Corbusier), Laurie Baker's low-cost houses | Post-1947 modernism; planned city |
Phases: early trading-post and church architecture (Portuguese Goa); Palladian and neo-classical government buildings (Calcutta, Madras); the Gothic Revival of Victorian Bombay (UNESCO listing of the 'Victorian Gothic and Art Deco Ensembles of Mumbai' in 2018, with Chhatrapati Shivaji Terminus inscribed in 2004); the Indo-Saracenic experiment of the 1870s–1910s; imperial New Delhi (the capital was moved from Calcutta, announced in 1911 and inaugurated in 1931); and the modernism of the independence years (Chandigarh).
Why Indo-Saracenic? Colonial rulers sought to appear as legitimate successors of the Mughals and to engage Indian princes' tastes while using engineering techniques and European plans. Critics see it as a 'cultural appropriation' with an imperial motive.

Answer skeleton — the Indo-Islamic synthesis
Introduction: Islamic arcuate forms met Indian trabeate techniques from the 12th–13th centuries; a creative synthesis — not mere imposition.
Body: (1) technical — arch, dome, minaret, squinch, mortar; (2) decorative — calligraphy and arabesque beside lotus, bell, kalash, chhatri and jali; (3) stylistic stages — imperial, provincial, Mughal, Deccani; (4) function — mosque, tomb, sarai, madrasa, garden; (5) regional adaptation — Mandu's lightness, Bengal's bangla roof, Gujarat's toranas; (6) craftsmen — Hindu masons and carvers worked on mosques and tombs.
Conclusion: a composite cultural heritage; sets the base for later Indo-Saracenic revival.
Gardens, water and city planning
The charbagh is a paradise-garden: four quadrants with water channels, found at Humayun's Tomb, Taj Mahal, Shalimar and Nishat Bagh, Mehtab Bagh and Pinjore. Step-wells and tanks supplied water to cities. Shahjahanabad's grid, the Chandni Chowk bazaar and the Fatehpur Sikri palace-city show Mughal planning. Jaipur (1727, Jai Singh II with Vidyadhar Bhattacharya) is a rare planned medieval city in a grid, a UNESCO site since 2019.
Preservation and heritage: current hooks
UNESCO sites of this chapter: Qutb complex and Humayun's Tomb (1993), Red Fort complex (2007), Agra Fort and Taj Mahal (1983), Fatehpur Sikri (1986), Jantar Mantar (2010), Rajasthan hill forts (2013), Rani ki Vav (2014), Chandigarh (2016), Ahmedabad (2017), Mumbai ensembles (2018), Jaipur (2019). Several of these are also tests of 'Misc / Important Places' questions in the Culture Grab-bag article.
How UPSC Has Asked It — And What Could Come Next
Seen: materials at Fatehpur Sikri and Lucknow (2018); medieval structures within wider medieval questions (2021, 2023).
Likely next: monument–dynasty or monument–city pairs (Alai Darwaza, Hindola Mahal, Atala Masjid, Adina Masjid, Gol Gumbaz); features (pietra dura, charbagh, pishtaq, squinch, jali, chhatri, batter); UNESCO sites (Humayun's Tomb, Qutb complex, Red Fort 2007, Agra Fort, Fatehpur Sikri, Taj, Rajasthan hill forts, Jaipur 2019, Ahmedabad 2017, Mumbai ensembles 2018, Chandigarh 2016); Mughal emperors and their buildings; colonial buildings and their architects.
Traps: Qutb Minar is not entirely Aibak's; the Alai Darwaza is Khalji, not Tughlaq; the Taj is Shah Jahan's but the first garden tomb is Humayun's; Bibi ka Maqbara is Aurangzeb's period; the Gateway of India is colonial (1924), not Mughal; Rashtrapati Bhavan was designed by Lutyens, not Baker alone.
