The Isa Khan tomb complex is a walled area adjacent to Humayun’s Tomb and is the resting place of Isa Khan Niyazi, a noble of influence at the court of Sher Shan Suri. A mosque and an octagonal tomb built in the Sur style are enclosed in Isa Khan’s walled complex. An inscription on a sandstone slab over the mihrab inside the tomb dates the construction to the Hijra year 954 (A.D. 1547-1548).
