We will explore the monastery’s water supply in the Middle Ages: From the Mühlbach ditch to the Ulrichsberg tunnel, into the Kehrer ditch to the ponds, and out to the old mill. The tunnel dates back to the 12th century and runs 110 m through the Ulrichsberg. Good footwear is required.
Tickets are available in the monastery shop. No registration required.
Meeting point: 2 PM in front of the monastery shop
