Bada Gumbad, Lodhi Garden, India
Bada Gumbad (literally "big dome") is situated in Lodhi Gardens, Delhi. The monument is located near the tomb of Sikander Lodhi and Sisha Gumbad. Although the three structures, which share a common raised platform, were all built during the Lodhi reign, they were not constructed simultaneously. The intended purpose and significance of Bada Gumbad is unknown and, to date, remains a mystery. Some historians suggest that the Bada Gumbad was built by an unidentified noble in 1490, before being appropriated by Sikander Lodhi in 1494, to provide an entryway to his mosque.
