Humayun, the son of Babur, was the second Mughal Emperor to have graced the throne of Delhi. He died in the year 1556. In 1562, six years after his death, his widow Hamida Banu Begam, also called as Haji Begam, commissioned the building of this tomb. It took eight years to create this architectural masterpiece. In 1570, Humayun’s Tomb, the first garden-tomb of the Indian subcontinent, came into being. It is probably the first major architecture of the Moghul rule and was an inspiration to the Taj Mahal. Located at Nizamuddin, this tomb stands as a great example of the amalgamation of Mughal and Persian styles of architecture. We can also say that this tomb is an apt example of Mughal architecture, inspired by the Persian style. Humayun was a great lover of Persian architecture. Some people also believe that Humayun himself had planned about this tomb, but there are no concrete records to back this romantic argument. The tomb was built in red sandstone and is octagonal in shape. As a large enclosure raised on a platform, with high arches and double domes, this magnificent monument appears as a striking structure. The tomb rests at the middle of the plinth, which is around 21 feet high. The height of the central dome of the tomb is about 140 feet. The double-layered dome enhances the aesthetic appeal of the architecture. Though by and large, the tomb has been made in red sandstone, but there is infusion of white marble at some places, which adds to the beauty of the tomb. No wonder, it happens to be a World Heritage Site.
