The mughals brought with them a love for gardens, fountains and water. The first mature example of Mughal architecture in India, Humayun's Tomb was built by the emperor's grieving widow, Haji Begum, in 1565 AD. Constructed with red sandstone and ornamented marks the beginning of a new tradition of ornate style which culminated in the Taj Mahal of Agra. Designed by the Persian architect, Mirza Ghyas, Humayun's Tomb shows a marked shift from the Persian tradition of using coloured tiles for ornamentation. Located in the midst of a large square garden, screened by high walls, with gateways to the south and west, the tomb is a square tower surmounted by a magnificent marble dome. The dome stands 140 feet from the base of the terrace and is topped with a copper pinnacle. In addition to the remains of Humayun, the complex also houses the grave of many other distinguished members of the Mughal dynasty. The first Mughal Emperor, Babur, was succeeded by his son, Humayun, who ruled in India for a decade but was expelled. Eventually he took refuge with the Safavid shah of Persia, who helped him regain Delhi in 1555, the year before his death. Humayun's Persian wife, Hamida Begum, supervised the construction from 1562-1572 of her husband's tomb in Delhi.
The architect, Mirak Mirza Ghiyuath, was Persian and had previously designed buildings in Herat (now northwest Afghanistan), Bukhara (now Uzbekistan), and elsewhere in India. The location chosen for the building on the bank of the Yamuna river adjoins the shrine of an important Sufi Chistiyya order saint, Nizam al-Din Awliya. The Chistiyya was particularly venerated by the Mughals; Humayun's son, Akbar, would build his new palace at Fatehpur Sikri next to the shrine of another saint of the Chistiyya order. The tomb established some of the important norms for later Mughal mausolea. It is set in a geometrically arranged garden criscrossed by numerous water channels and probably representing symbolically a paradise setting.
