The Mughals carried their love of water, gardens, and fountains with them. Haji Begum, the bereaved widow of the emperor, constructed Humayun's Tomb in 1565 AD, the first complete example of Mughal architecture in India. The Taj Mahal of Agra served as the pinnacle of a new tradition of extravagant design that began with the red sandstone structure that was embellished. The Persian architect Mirza Ghyas' design for Humayun's Tomb departs noticeably from the Persian custom of decoration with coloured tiles. The mausoleum is a square tower with a spectacular marble dome on top. It is situated in the middle of a sizable square garden that is surrounded by high walls and has doors to the south and west. The dome has a copper pinnacle on top and is 140 feet tall above the terrace's base. (Closed on Mondays). Book a Delhi tour package and visit Lotus Temple.
