Postcard Kruttornet Visby
Kruttornet is the oldest tower in the city wall of Visby and was built as a defensive tower to protect the medieval harbour, which was located in the part of Visby now known as Almedalen
park. It was built in 1160–61, in connection with the conclusion of a trade agreement with the Duke of Saxony
as a free-standing defensive tower. Originally an identical tower, which has since disappeared, existed on the opposite side of the harbour entrance. UNESCO World Heritage Site
