Indo-Islamic architecture
A style developed through the interaction of Islamic architectural traditions with the building practices, materials and spatial traditions of the Indian subcontinent. Beginning with the establishment of Islamic rule in parts of India and evolving through the Delhi Sultanate, Mughal and regional periods, this architecture produced a distinctive vocabulary of domes, arches, courtyards, prayer halls, gateways and minarets. Rather than being a simple replacement of Indian traditions with Islamic forms, Indo-Islamic architecture often involved adaptation and synthesis. Local craftsmanship and established Indian construction techniques were combined with architectural ideas associated with the wider Islamic world.
Mosques such as the Jama Masjid in Delhi and monumental complexes such as Fatehpur Sikri, including the Buland Darwaza, demonstrate this architectural exchange particularly well. Understanding the terminology behind these buildings makes it easier to read their plans, sections and façades and understand how individual elements contribute to religious function, circulation and architectural expression.
Indo-Islamic architecture terminology
Aisles
Aisles are longitudinal passageways running parallel to the main prayer space, typically separated by rows of columns or piers. In large Indo-Islamic mosques, multiple parallel bays could accommodate worshippers while maintaining an organised circulation pattern. Their arrangement helped divide expansive prayer halls into manageable structural units while allowing large congregations to pray within a continuous architectural space.
Chhatri
A chhatri is a small elevated pavilion, generally covered by a dome or similar roof and supported by columns. The word comes from the Hindi term for “umbrella,” reflecting its canopy-like form. Chhatris originated within Indian architectural traditions and were incorporated extensively into Indo-Islamic and later Mughal and Rajput architecture.
They commonly appear on rooflines, gateways, palace structures, tombs and building corners, where they provide visual emphasis and vertical rhythm. Their use demonstrates how indigenous Indian architectural elements were incorporated into buildings influenced by Islamic architectural traditions.
Darwaza / Main Entrance
A darwaza is a monumental gateway providing access to an important building, courtyard or architectural complex. In Indo-Islamic architecture, gateways could become major architectural features in their own right, using large arched openings, domes, decorative stonework and monumental proportions to mark transitions between spaces.
The Buland Darwaza at Fatehpur Sikri is one of the most prominent examples. Built during the reign of Akbar, its enormous scale and elevated position create a dramatic approach to the complex while establishing a strong visual entrance.
Haud / Tank
A haud is a water tank or reservoir associated with a mosque or religious complex. In mosque architecture, water is traditionally provided for wudu, the ritual washing performed before prayer.
The tank is generally positioned within or near the mosque courtyard, making water readily accessible to worshippers. Besides its religious function, the presence of water can also contribute to the environmental character of the courtyard by introducing a cooling and reflective surface.
Liwan
A liwan is a covered architectural space opening onto a courtyard, usually along one or more sides of the open space. It can function as a prayer or gathering area and is typically defined by a roof supported by columns, piers or arches.
The arrangement creates a gradual transition between the completely open courtyard and more enclosed interior spaces. In Indo-Islamic architecture, covered courtyard edges often provide shaded areas for circulation, gathering and additional prayer space.
Mihrab
A mihrab is a recessed feature in the qibla wall of a mosque that indicates the direction of prayer. It provides a clear visual focus within the prayer hall and identifies the wall facing the Kaaba in Mecca.
Mihrabs in Indo-Islamic mosques range from relatively simple recessed niches to highly ornamented architectural compositions incorporating arches, calligraphy, geometric patterns and stone carving. Importantly, the mihrab indicates the direction of prayer; it is not itself the qibla.
Minaret
A minaret is a tall, vertically proportioned tower associated with a mosque. Historically, minarets were used as elevated locations from which the adhan, or call to prayer, could be proclaimed. Over time, they also became prominent visual markers of Islamic religious architecture.
Indo-Islamic minarets vary considerably in form, from slender cylindrical towers to more elaborate structures with balconies, carved surfaces and multiple levels. Their height and vertical emphasis create a strong contrast with the horizontal mass of the mosque and help establish its presence within the surrounding cityscape.
Nave
A nave is the principal central longitudinal space within a large prayer hall, positioned between or alongside rows of supporting columns or piers. In a mosque, the central prayer space can be more prominent than adjacent bays because of its relationship to the principal entrance, qibla wall or major architectural axis.
Onion-Shaped Dome
An onion-shaped dome is a bulbous dome that swells outward before curving inward towards a pointed or rounded crown. The form became particularly prominent in later Indo-Islamic and Mughal architecture, where domes evolved into increasingly expressive silhouettes.
The bulbous profile can create a strong vertical emphasis while allowing the dome to dominate the skyline of a building. Its use became especially associated with Mughal architectural expression, although similar bulbous dome forms occur across several architectural traditions and periods.
Qibla
The qibla is the direction towards the Kaaba in Mecca that Muslims face during prayer. In mosque architecture, this direction determines the orientation of the principal prayer space and the wall containing the mihrab.
Unlike a physical architectural object, the qibla is a directional and spatial principle that influences the planning of the mosque. The orientation of the prayer hall, position of the mihrab and arrangement of worshippers are all organised in relation to it.
Riwaq / Colonnade
A riwaq is a covered gallery or passage, generally formed by a series of columns, piers or arches and often positioned along the edge of a courtyard. It provides shade and creates a transitional zone between the open courtyard and enclosed architectural spaces.
In large Indo-Islamic mosque complexes, riwaqs can extend along multiple sides of a sahn, creating continuous shaded circulation and additional areas for gathering or prayer.
Sahn / Courtyard
A sahn is the open courtyard of a mosque, generally positioned between the principal prayer space and surrounding architectural elements. It provides an open area for circulation, gathering and, where required, additional space for congregational prayer.
The courtyard frequently acts as the organisational centre of a mosque, connecting the prayer hall with surrounding galleries, entrances and ablution facilities. In large Indo-Islamic mosques, its scale can also provide a strong sense of monumentality by creating a large open void within the built complex.
Conclusion
Indo-Islamic architecture represents a long process of architectural exchange rather than a single uniform style. Its buildings combine Islamic religious requirements with Indian materials, craftsmanship, construction traditions and architectural forms. Terms such as qibla, mihrab, sahn, riwaq, minaret and haud describe functional and spatial components of mosque architecture, while elements such as chhatris and monumental darwazas demonstrate the incorporation and reinterpretation of regional Indian traditions.
Learning this vocabulary provides a useful foundation for analysing Indo-Islamic buildings. Once the relationship between each element and the larger architectural composition is understood, monuments such as the Jama Masjid and Fatehpur Sikri become much easier to read as organised systems of space, movement, structure and symbolism.
