Under the guidance of a guide, you can participate in an excursion to the Batterie position on Schiermonnikoog for the day. This position was the major artillery position on the island during World War II.
The excursion starts with a minimum of 8 participants at the Bunkermuseum Schlei. Participants will need their own or rented bikes. Considering the time it takes to reach the Batterie, this excursion will likely be done twice.
