The Taj Mahal has become one of the world’s best known monuments. This domed white
marble structure is situated on a high plinth at the southern end of a four-quartered garden,
evoking the gardens of paradise, enclosed within walls measuring 305 by 549 metres. Outside
the walls, in an area known as Mumtazabad, were living quarters for attendants, markets, serais
and other structures built by local merchants and nobles. The tomb complex and the other
imperial structures of Mumtazabad were maintained by the income of thirty villages given
specifically for the tomb’s support. The name Taj Mahal is unknown in Mughal chronicles, but
it is used by contemporary Europeans in India, suggesting that this was the tomb’s popular
name. In contemporary texts, it is generally called simply the Illuminated Tomb (Rauza-i-
Munavvara).
Mumtaz Mahal died shortly after delivering her fourteenth child in 1631. The Mughal
court was then residing in Burhanpur. Her remains were temporarily buried by the grief-
stricken emperor in a spacious garden known as Zainabad on the bank of the river Tapti. Six
months later her body was transported to Agra, where it was interred in land chosen for the
mausoleum. This land, situated south of the Mughal city on the bank of the Jamuna, had
belonged to the Kachhwaha rajas since the time of Raja Man Singh and was purchased from
the then current raja, Jai Singh. Although contemporary chronicles indicate Jai Singh’s willing
cooperation in this exchange, extant farmans (imperial commands) indicate that the final price
was not settled until almost two years after the mausoleum’s commencement. Jai Singh’s
further cooperation was insured by imperial orders issued between 1632 and 1637 demanding
that he provide stone masons and carts to transport marble from the mines at Makrana, within
his “ancestral domain”, to Agra where both the Taj Mahal and Shah Jahan’s additions to the
Agra fort were constructed concurrently.
Work on the mausoleum was commenced early in 1632. Inscriptional evidence indicates
much of the tomb was completed by 1636. By 1643, when Shah Jahan most lavishly celebrated
the ‘Urs ceremony for Mumtaz Mahal’, the entire complex was virtually complete.

marble structure is situated on a high plinth at the southern end of a four-quartered garden,
evoking the gardens of paradise, enclosed within walls measuring 305 by 549 metres. Outside
the walls, in an area known as Mumtazabad, were living quarters for attendants, markets, serais
and other structures built by local merchants and nobles. The tomb complex and the other
imperial structures of Mumtazabad were maintained by the income of thirty villages given
specifically for the tomb’s support. The name Taj Mahal is unknown in Mughal chronicles, but
it is used by contemporary Europeans in India, suggesting that this was the tomb’s popular
name. In contemporary texts, it is generally called simply the Illuminated Tomb (Rauza-i-
Munavvara).
Mumtaz Mahal died shortly after delivering her fourteenth child in 1631. The Mughal
court was then residing in Burhanpur. Her remains were temporarily buried by the grief-
stricken emperor in a spacious garden known as Zainabad on the bank of the river Tapti. Six
months later her body was transported to Agra, where it was interred in land chosen for the
mausoleum. This land, situated south of the Mughal city on the bank of the Jamuna, had
belonged to the Kachhwaha rajas since the time of Raja Man Singh and was purchased from
the then current raja, Jai Singh. Although contemporary chronicles indicate Jai Singh’s willing
cooperation in this exchange, extant farmans (imperial commands) indicate that the final price
was not settled until almost two years after the mausoleum’s commencement. Jai Singh’s
further cooperation was insured by imperial orders issued between 1632 and 1637 demanding
that he provide stone masons and carts to transport marble from the mines at Makrana, within
his “ancestral domain”, to Agra where both the Taj Mahal and Shah Jahan’s additions to the
Agra fort were constructed concurrently.
Work on the mausoleum was commenced early in 1632. Inscriptional evidence indicates
much of the tomb was completed by 1636. By 1643, when Shah Jahan most lavishly celebrated
the ‘Urs ceremony for Mumtaz Mahal’, the entire complex was virtually complete.
