Humayun’s Tomb in New Delhi, India, was recognised as a UNESCO World Heritage Site in 1993. And that’s not surprising, considering the splendid architecture of this royal Tomb. Some say that the Taj Mahal in Agra was modelled after Humayun’s Tomb, and this is not that difficult to believe. The two share several common design elements, including an elevated base and a large central dome. Whether or not that is true, though, Humayun’s Tomb is a stunning monument and deserves its place on the World Heritage List.
