The castle where the villains were hiding
Bassie & Adriaan: De verdwenen kroon
The crooks hid in Slot Teylingen after they stole the crown and wanted to take revenge on Bassie and Adriaan.
This is perhaps Bassie & Adriaan's most famous location.
This ruin is maintained by volunteers and is therefore not always open.
The bushes in front of the secret entrance (which is actually a small toilet room in the ruins) have been removed because they damaged the wall. The ferry to the other side is also no longer there and another entrance has now been made.
