Mosque at Isa Khan's Tomb

This is the mosque at the west end of Isa Khan's garden tomb, and while not one of the largest examples of a tomb mosque, it is one of the oldest and most colorful.
Isa Khan's tomb is a part of the Humayun's Tomb complex in Delhi, India, and was built around 1547-1548. The tomb and its surrounding sunken garden is one of the earliest known examples and was said to have been part of the design inspiration for more famous sunken garden tombs in the future like the Taj Mahal.
