The Taj Mahal is a mausoleum complex built by Shah Jahan (reg. 1628 - 1658) in memory of his favorite wife, Arjumand Banu Begam (d.1631), better known by her title "Mumtaz Mahal," or "the exalted one of the palace." The construction of the complex began shortly after Mumtaz's death and the tomb's fame increased over time.

The Taj Mahal complex is organized in a rectangle, measuring approximately 310 x 550 meters. It comprises a number of buildings and structures, all functioning together as the funerary monument for Mumtaz Mahal. From the south, the first part of the complex consists of a (former) bazaar, the forecourt and entry gates; the second part consists of a large garden and garden pavilions, axially arranged along a riverfront terrace with the three main structures: the mosque, the mausoleum and the mihmankhana (literally, "guest house," probably used as an assembly hall).

The complex was planned on the basis of a unit called a gaz, approximately 32 inches (81.28 cm). Multiples of this "gaz" unit were used throughout the Taj Mahal complex. …These gaz modules lend themselves to an axial arrangement, with a cascading hierarchy: each building in the complex is further organized on a smaller grid based on the gaz module. For example, the mosque, mausoleum and mihmankhana are based on a 7-gaz grid, while the great gate (darwaza-i rauza) is based on a 3-gaz grid. This grid functions not only in plan, but also in elevation.

Taj Ganj and Entrance Gates

The Taj Ganj market aligned on axis with the southern entrance gate of the Taj complex once served as a vital part of the entire complex. From present images it is difficult to see that this market, irregular in appearance, was once a busy marketplace and caravanserai. A small-scale bazaar, it was incorrectly referred to as 'Tage Gunge' or 'Tadgundy' by foreign travelers. This bazaar was a shopping district in the 1640s, but due to a decline in trade, it lost its prominence by the 1650s.

The great gate (darwaza-i rauza) that leads from the north of the jilaukhana to the garden, and ultimately to the mausoleum of Mumtaz Mahal, is a large structure with triadic openings.

Garden (Bagh-i Firdaus-a'in) and Naubat Khanas

The garden (bagh-i firdaus-a'in) of the Taj complex is laid out as a cross-axial chahar bagh: a large square divided into four equal quadrants by two large primary intersecting walkways (khiyaban). Each of these quadrants is further divided into four sections by smaller secondary intersecting walkways.

Riverfront Terrace

In historic accounts of the Taj Mahal complex, the riverfront terrace supporting the mausoleum has been referred to as the kursi, or throne. This terrace, and the marble plinth upon it, supports the mosque, mausoleum and the mihmankhana.

Mausoleum

At the north end of the garden is the mausoleum of Mumtaz Mahal (rauza-i munauwara, rauza-i muqqadas, rauza-i mutahhara), the central element of the Taj Mahal complex. The plan of the mausoleum is based on the nine-fold hasht-bihisht (eight paradises) plan often employed by the Mughals for tomb and pavilion design in the 16th and early 17th centuries. In this system, a square plan is divided into nine spaces: a central chamber with four additional spaces in the center of each elevation and four rooms at each corner.

In the mausoleum of the Taj Mahal complex, the central chamber is double-height and octagonal in plan. At its center rest the cenotaphs of Mumtaz Mahal and Shah Jahan. The chamber is capped by a shallow dome and decorated with niches on each two-story wall.

Ambulatory rooms (shish mahal) are placed on the cardinal axes of the octagonal tomb chamber on both stories. Cruciform in plan, the walls and ceilings of the shish mahal rooms are composed of of glass-filled decorative patterns. These rooms are not accessible to visitors.

The floor of the tomb chamber is tiled with octagonal marble stars in alternating cruciform modules, each outlined with inlaid black stone. The delicate marble screen that currently surrounds the cenotaphs of Shah Jahan and Mumtaz was set up in 1643 in place of the original gold-enameled one that was made in 1633 on the second anniversary (urs) of Mumtaz's death.

The cenotaph of Mumtaz Mahal is a rectangular block placed on a platform decorated with Quranic verses on the upper block and naturalistic motifs on the lower base. A symbolic pen case sits atop Shah Jahan's cenotaph, which, although similar, is slightly larger in size and has more vegetal motifs than Mumtaz's cenotaph. Shah Jahan's cenotaph is placed parallel and slightly offset (sheared) in relation to Mumtaz's cenotaph.

The interiors of the four central pishtaqs are adorned with floral mouldings conjecturally inspired by European paintings of the 16th and 17th century (Shah Jahan's artisans were notably familiar with the works of their European contemporaries). The frame of the mausoleum's central pishtaqs, as with other similar forms within the complex, is decorated with an inlaid thuluth inscription of a Quranic verse. At the pishtaq's highest point is a linear pattern of floral motifs running between two extended engaged columns capped with guldastas. The spandrels of the pishtaq are also filled with an inlaid mirror-symmetrical arabesque pattern in red, green and dark yellow stones, and the pointed arch of the frame is outlined with rope-form moldings.

Minarets

Four marble-clad minarets flank the mausoleum, one at each corner of the mausoleum plinth. Minaret additions were not prevalent in Mughal building until the 17th century, and can also be seen in the gateway of Akbar's tomb in Sikandra, as an addition, and at the tomb of Itmad-ud Daula in Agra. In both cases, the minarets were still not detached from the main structures.

Mosque and Mihmankhana

The mosque and mihmankhana are located to the west and east (respectively) of the mausoleum building. Symmetrical and identical in design, it is conjectured from records that the mosque was built first, followed by the mihmankhana. The mihmankhana's function was, speculatively, to accommodate visitors during Mumtaz's urs, and to balance the architectural composition.

The mosque has a mihrab in its qibla wall, highlighted by a marble frame with an inscription of the Sun (al-Shams) sura.

Riverfront Towers

Four identical tower pavilions are found at each corner of the riverfront terrace, forming anchor points towards the riverfront. The towers are clad in red sandstone and have floral motifs carved in relief with marble inlays on panels.

Materials and Construction

The materials most frequently used in the Taj Mahal complex are bricks, sandstone and white marble. Brick sizes varied between 18-19 x 11-12.5 x 2.3 cm, (roughly) a standard size since Akbar's rule. These bricks were baked in kilns on the outskirts of Agra. The sandstone was brought from Fatehpur Sikri, about 40 km west of Agra and Rupbas, 45 km southwest of Agra. The sandstone used in the complex has a color varying from soft red to red with a yellow tint. White marble came from the quarries of Makrana in Rajasthan, approx. 400 kms southeast of Agra (Shah Jahan had initially acquired the site for the Taj Mahal complex from Raja Jai Singh of Makrana). The marble used in the complex was a white one with black and grey streaks. Although difficult to work, it was hard enough for detailed carving, with a translucent appearance. This translucence is most visible during changes in daylight, when the monument appears to glow.

The buildings in the Taj Mahal complex are built of brick and faced with sandstone or marble, using a technique called the "Mughal bond." These walls, filled with brick and/or rubble and mortar, have a course of sandstone (such that the edge of the sandstone slab becomes part of the façade and its width spans the wall) as well as sandstone tie-backs, where the sandstone is set perpendicular to its bedding plane and one of its edges is visible on the façade (while its length also runs through the thickness of the wall). A final piece of sandstone acts as simple cladding, placed on the façade perpendicular to its bedding plane, held in place by mortar backing and iron dowels or clamps. Vaults, such as the inner dome of the mausoleum, were constructed with concentric rings of brick plastered with thick layers of mortar.

Precious and semi-precious stones are used more extensively in the decoration of the mausoleum than elsewhere in the complex. These stones include lapis lazuli, sapphire, cornelian, jasper, chrysolite and heliotrope. A strict discipline in colors and patterns is visible in the detailed ornamentation of the Taj.
