The coastal fortress Oscarsborg now runs its very own Escape Room based on the incredibly important events of 9 April 1940, when the fortress helped sink the German heavy cruiser Blücher in the Oslofjord, playing a significant role in Norway’s history. Recreating the events in one hour, the people in the Escape Room must solve a mystery relating to the events of that day. “It’s an incredible experience,”, explains Tony Eide, owner of the hotels. “It’s based entirely on that day, which makes it a thrilling task for those taking part in it.” Oscarsborg is located a mere 30 minutes from Oslo.
