Fort Vredeburg is a fortress built by the Dutch in Yogyakarta during Colonial times. It is located in front of Gedung Agung, one of seven presidential palaces in Indonesia and the Sultan Palace called Kraton. It was built in 1765 to protect the Dutch governor. It is surrounded by a trench that is still visible.
This square-shaped fortress has a watchtower at each of its four corners. In the past, the Dutch troops patrolled frequently on its wall.
Nowadays, the fortress has become a museum. In some buildings in the fortress there are dioramas on Indonesian history.
