Originally built as part of the city’s fortifications in the second half of the 14th century, the complex was rebuilt by Antoni Van Obberghen between 1593 and 1604 with the smaller of the two buildings becoming a torture chamber and courthouse while the larger tower became the prison. It was here that executions were carried out until the middle of the 19th century. Damaged during WWII, it has been extensively renovated and how houses the Amber and Torture Museums.
