The former seat of the Counts of Egmont, set in a small park at the edge of the centre. The current building is largely an 18th- and 19th-century reconstruction on much older foundations, but it remains the most evocative spot in Zottegem and houses some municipal functions.
The grounds are open to the public for free and are worth a walk for the moat, the trees, and the simple stone bridge across to the entrance. The interior is rarely accessible to visitors, but the museum in the old town hall covers the family's history.
