Vyborg castle was founded in 1293 Swedish Crusader Torgerson Knutson, after it was rebuilt several times, but in General almost did not change its appearance. The castle is situated on an island which can be reached on foot from the bridge across the Bay there is a descent straight to the castle gates. By area, the castle is small, and has no walls — instead of them around the perimeter of the castle built powerful residential and commercial buildings with corner towers, built of boulders.

Inside the castle there are three small patio (Lower, Upper and Forging), and narrow, curved, cobblestone, rising upward street. The lower part of the castle all built of dark stones, and over all the buildings high rises Grand white tower of the Bishop Olaf, a true symbol of Vyborg — tower can be seen from any point of the city.

The Olaf tower, with a huge cuboid hexagonal base and top, was built in the XIII century, several times overbuild and had a height of 80 meters, but after the fire in the eighteenth century was heavily rebuilt, and now her height is only 45 meters. The tower you can climb and admire the panorama of old Vyborg Bay and endless wooded skerries.

At the foot of the tower is tiny Forge courtyard, from which you can get into the Museum, and historical reenactment center, where you can put on armor, take up the spear or sword and shield, and take a picture for little money.
