The Kramat is situated to the west of the Maximum Security Prison (MSP). It is a shrine built for the Prince of Madura, Pangerau Chakra Deningrat who died on the Island in 1754.
The graves of Hadjie Matarim who died in 1755, and two other Muslim exiles are located behind the Kramat, on its west side. It is believed that this graveyard could be bigger, with more Muslim graves outside the fenced area of the Kramat. The Kramat as it exists today was rebuilt by prisoners in 1967.
