Mughal Architecture and Building Methods

From the sixteenth-century tombs of Akbar’s reign to Shah Jahan’s monumental marble projects and provincial buildings of the eighteenth century, Mughal architecture joined established South Asian building skills to court forms circulating across the Persianate world. A palace audience hall, a mosque and a tomb asked builders to solve different problems of access, shelter, prayer and commemoration. Their work depended on foundations, masonry, timber, plaster and skilled labor as much as on the finished façade.

Materials and foundations

Builders used brick and dressed stone, blocks cut to regular faces, for structural walls, then applied stone facing, plaster or tile where a patron wanted a finished surface. At the Taj Mahal, brick is laid in lime mortar, a lime-based binder that holds masonry together, beneath sandstone and marble facing. At Humayun’s Tomb in Delhi, India, built in the 1560s under Akbar’s patronage, dressed stone is faced with red sandstone and outlined with white and black marble. At the Agra Fort, Shah Jahan’s palace also used brick and red sandstone beneath a plaster finish, while other royal rooms used marble. Humayun’s Tomb has a high platform with vaulted cells on four sides; large recessed arches and smaller arches articulate each face. This is an early imperial dynastic tomb, raised on a broad terrace rather than set directly at ground level.

Foundations were another part of the design. A 2018 engineering study describes the Taj Mahal’s foundation system as wells, arches and piers made from stone blocks, bricks, watertight mortar and local materials. The account shows how foundation design combined masonry with water-resistant materials on the Yamuna riverbank.

Columns, arches and domes

Mughal projects used both column-and-beam construction and vaulted masonry. At Fatehpur Sikri, Akbar’s capital near Agra in northern India from 1571 to 1585, carved sandstone columns and brackets carry horizontal beams around courts and pavilions. This post-and-lintel method had deep roots in South Asian building. An arch spans an opening with wedge-shaped masonry; its weight presses down and outward onto the supporting piers, so walls or buttresses must resist that outward push. A vault extends the arch across a room. Builders could therefore roof larger spaces without carrying a stone beam across the whole opening. These methods coexisted: an arched entrance might open into a court lined with columns and beams.

Domes crowned tomb chambers and mosques, while smaller chhatris, or roof pavilions, punctuated terraces and rooflines. To set a round dome over a square room, builders could use squinches: small arches built across the upper corners to turn the square into an octagon or another polygon that supports the dome. Humayun’s Tomb has a double dome, with a marble-clad outer profile above its central chamber; the two shells let its exterior rise above the inner ceiling of the tomb room. Its octagonal interior opens into vaulted compartments and connecting galleries, so the tomb combines a central commemorative room with circulation and burial spaces around it. At the Taj Mahal, the raised octagonal tomb chamber, four corner minarets and separate mosque and guesthouse make the complex’s arrangement legible from its broad platform.

Labor, organization and craft

Large works brought together masons, stonecutters, inlayers, carvers, painters, calligraphers and dome builders. UNESCO’s Taj Mahal account describes artisans recruited from across the empire and from Central Asia and Iran. The official chronology gives 1632–1648 for the mausoleum and 1653 for the completed mosque, guesthouse and outer works. These dates show that a celebrated monument was a sequence of coordinated projects, not a single finished building campaign.

Building images and work records offer glimpses of the labor behind the stone. In a construction scene painted around 1595 for the Akbarnama, women pound limestone, sieve lime and carry bricks and lime to bricklayers. Historian Shireen Moosvi also notes that Abu’l-Fazl’s A’in-i Akbari lists piece rates for some imperial construction tasks. The image represents work through a court painter, while the rate lists are administrative evidence; together they show different kinds of labor and ways that patrons organized it.

Surface work required its own specialists. A late-sixteenth-century red-sandstone jali, or pierced screen, now in the Metropolitan Museum of Art was carved from a single slab into interlocking stars and hexagons. Its openings admitted light while laying the same geometry across the floor. At the Taj Mahal, floral designs were made by fitting semiprecious stones into the marble. In this inlay process, craftsmen cut shallow recesses into the marble and shaped small stone pieces to sit flush with its surface. The mosque and guesthouse use red sandstone with white-marble borders and stone inlay around their arches. Carved, pierced, painted and inlaid surfaces were distinct crafts, each tied to a particular material.

Imperial buildings and regional work

Palaces organized movement through courts and audience spaces. Fatehpur Sikri’s sandstone courts, pavilions and carved brackets differ from the river-facing apartments of Delhi’s Red Fort, where a linked row of royal pavilions was served by the Nahr-i Bihisht channel. Both show how an imperial residence could combine structural supports with passages, screens and decorated rooms, but their plans served different settings.

In Bengal, where good building stone was less readily available locally, Mughal builders adapted imperial forms to brick construction and older regional traditions. UNESCO’s account of Mughal mosques in present-day Bangladesh describes one-aisled prayer halls divided by lateral arches, often with one or three bays, and domes set on octagonal drums, the short polygonal bases between a roof and a dome. The projecting cornice marks the roof edge and shelters the wall below. The nomination also records continued use of curved cornices and terracotta ornament inherited from Sultanate-period Bengal. The UNESCO list dates the three-domed Khan Mohammad Mridha Mosque in Dhaka to 1704–1705, a named example of this regional building tradition. Dhaka’s Bara Katra, built in 1644–1646, was a brick courtyard complex with arched rooms and endowed shops that helped support traveller lodging and upkeep. Provincial work adapted materials and forms to local patrons and building practices rather than simply copying an imperial marble monument.
