With a history dating back thousands of years, the city of Delhi has been destroyed and rebuilt numerous times by numerous leaders. Purana Qila serves as a reminder of the capital’s turbulent past as one of the oldest structures in Delhi and its oldest surviving fort.
Purana Qila was built during the rule of Afghan ruler Sher Shah between 1538 and 1545 in the midst of a power struggle between him and Humayun, the son of Babur, the first Mughal emperor. Humayun had built his own fort in the same spot in the 1530s but was forced out by Sher Shah, who proceeded to destroy what Humayun had built and establish his own capital.
Today, all that remains of Purana Qila are the massive red sandstone
ramparts with three gateways providing entrance. Within the old fort,
only two buildings remain, Sher Shah’s personal mosque -- a pre-Mughal
domed structure dating back to 1941, and a two-floor sandstone and
marble tower used by Humayun as a library after he retook the city in
