Humayun's Tomb is a mausoleum located in Delhi, India. It was commissioned by Humayun's wife, Empress Bega Begum, in the mid-16th century and was the first significant example of Mughal architecture in India. The tomb was built using red sandstone and white marble, and its design served as the prototype for many other Mughal monuments, including the Taj Mahal.

The tomb complex covers over 27 acres and features well-manicured gardens, which are said to have been influenced by Persian and Charbagh designs. The main tomb structure is a double-domed building that rises over 50 meters into the air, and its walls are adorned with intricate carvings and inlay work. The interior of the tomb is particularly noteworthy, with its central chamber containing a raised platform that holds Humayun's cenotaph, or false tomb.

Humayun's Tomb was declared a UNESCO World Heritage Site in 1993 and has been undergoing restoration and preservation work ever since. Today, it is one of Delhi's most popular tourist attractions and draws thousands of visitors each year who come to admire its beautiful architecture and peaceful setting.
