Hampi is the site of the ruins of Vijayanagara, the capital of the Vijayanagara Empire. The Mahanavami Dibba is a massive stone platform located in the Royal Centre area of Hampi. It is believed to have been used by the Vijayanagara rulers for public ceremonies, especially during the Mahanavami festival (now celebrated as Navaratri or Dasara). Ujjain, Gaur, and Mandu were important historical cities but were not the capital of the Vijayanagara Empire.
