Isa Khan's Tomb:

The Tomb of Isa Khan, located outside the main grounds of Humayun's tomb, was built in 1547. It commemorates an important notable who served Sher Shah, the Afghan ruler of Delhi who had ousted Humayun.

The octagonal form of the tomb has a long history in Islamic art and became popular in India in the second half of the fourteenth century for members of ruling families. Its particular evocation of the form is noteworthy for the elegant clustering of kiosks (chatris) and pinnacles around the dome.
