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.
