Takht-i-Bhai is another well-known and preserved monument, a Buddhist monastery located on a rocky ridge about 10 miles northeast of Mardan. This structure dates back to two to five century AD and stands 600 feet above the plane. The feature, which distinguishes this site from others, is its architectural diversity and its romantic mountain setting. The uphill approach has helped in the preservation of the monument.
The exposed buildings here include the main stupa and two courtyards in different terraces surrounded by votive stupa and shrines, the monastic quadrangles surrounded by cells for the monks, and a large hall of assembly. In one of the stupa courtyard is a line of colossal Buddhas, which were originally 16 to 20 feet high.
