Vyborg Castle

Vyborg Castle is a Swedish-built medieval fortress around which the town of Vyborg evolved. The first record of the castle dates back to 1293. Currently it serves as a museum.

Vyborg Castle was one of the three major castles of Finland. It was built as the easternmost outpost of the medieval Kingdom of Sweden: it is located on the Karelian Isthmus, on a little islet in the innermost corner of the Gulf of Finland, in a tight strait which connects Suomenvedenpohja to the Bay of Viipuri. It was originally constructed in the 1290s on the site of Karelian fortress after the Third Swedish Crusade to Finland. The town was originally located inside the outer fortifications of the castle, at the fortress island, but it had to be moved to its present location off of the island because of lack of space.
