Nila Gumbad () is a tomb located within the Humayun's Tomb complex at Delhi, India. Historians are unsure about the identity of the person who has been buried. Some claim that it houses the tomb of an attendant of a Mughal noble and was buried during the reign of Jahangir. According to others, the tomb existed much before the Humayun's Tomb was constructed. At the time of construction, it was covered with glazed tiles most of which have been destroyed. This building along with other buildings form the UNESCO World Heritage Site of Humayun's Tomb complex. Read more on Wikipedia
