The Castle is the oldest building in South Africa. It was built between 1666 and 1667 and made with timber from Houtbay and stone from Robben Island.

Today it hosts the Good Hope Gallery and the Military museum. There are guided tours every hour where one can visit the torture chamber and dark dungeons. It is still possible to see the messages carved out on the doors by hopeful prisoners.

It is said that there are a number of ghosts in the castle like an unloved 18th Century governor and a mysterious "grey lady".
