Bara Lao Ka Gumbad is a historical monument located in the Vasant Vihar area of Delhi, believed to have been constructed during the late Lodhi period in the 15th or early 16th century. The monument’s name, "Bara Lao Ka Gumbad," translates to "the domed structure of the twelve slabs," though there is no definitive record explaining the exact significance of the name. The Gumbad (dome) is a typical example of Lodhi-era architecture, characterized by simplicity and symmetry. The structure is square in plan, with thick walls and arched openings on all four sides, topped by a large hemispherical dome. This style is consistent with other tombs and mosques built during the Lodhi dynasty, which emphasized modesty in design with restrained ornamentation. While it’s uncertain who was buried here or if it served as a tomb at all, the structure is believed to have been a tomb due to its architectural style, similar to other Lodhi tombs. The monument is located in a relatively secluded and residential part of Delhi, lea
