Humayun’s Tomb is a tomb in Delhi, the capital of India, which was built in the 16th century. It is the burial place of the second Mughal Emperor, Humayun. Following the emperor’s death, his widow order the construction of the tomb, which took place over nine years. The mausoleum features beautifully contrasting white marble and red sandstone, and is built in the center of a huge square Charbagh (four-square garden), which covers over 10 hectares. It became the basis for the architecture style known as Mughal architecture, which incorporates aspects of traditional Indian and Persian architecture in many areas. Mughal architecture was also very influential on the Taj Mahal. Humayun’s Tomb was listed as a World Heritage Site in 1993.
