Velvet Cave
Fluweelengrot
A marl cave beneath the castle ruins, connected to the castle's secret passages. It preserves murals and charcoal graffiti, and it hosts a winter Christmas market.
The Velvet Cave is located beneath the castle hill. It is a marl gallery left by centuries of quarrying. Some passages once connected to the castle, and the cave served as a shelter in wartime. Its walls preserve charcoal signatures, murals and carvings from several centuries, as well as a small underground chapel. Visits are usually one-hour guided tours, with English-language sessions available. Tickets cost about €10 and can be bought together with the castle ruins. From mid-November to late December, the cave turns into one of two cave Christmas markets, and tickets must be bought for specific time slots.
Opening hours
About 10:00–17:00, by guided tour session
