Inside the castle there are three small patio (lower, upper and Blacksmith) and narrow, arched, paved with cobblestones, street rises to the top. The lower part of the castle, all built of dark stones, and above all the high rise buildings grand white tower bishop Olaf, a true symbol of Vyborg - the tower can be seen from anywhere in the city.
