Olofsborg
Medieval Olavinlinna is the city's symbol and main attraction. Built in 1475 by Danish knight Erik Axelsson to protect the eastern border of the Swedish-Danish Kalmar Union, it was named after the patron saint of knights, St. Olaf. The Russians were soon on the offensive, but the castle withstood several sieges before capitulating in 1714. The Swedes recaptured it in 1721, but lost it again in 1743, and it stayed in Russian hands until Finnish independence. This explains why it has stayed in such good shape: for the Russians, it was far inland and militarily useless, and hence not a target for the enemy either. Today, Olavinlinna is the world's northernmost medieval stone castle and easily Finland's best-preserved and most attractive castle, and it's quite a sight perched on the shores of the lake. The interior, though, is surprisingly small and sparse (virtually all furniture and decorations were lost in fires around 1870), and free guided tours take one hour. There are small exhibits inside the castle. Guided tours in English run every hour in summer (enquire in advance at olavinlinna@nba.fi in other seasons), but you can also visit the museums and courtyards on your own (entrance to some areas only on a tours.
Provincial museum Riihisaari
On Riihisaari island you can learn more about the cultural history and the nature of the region around Lake Saimaa and also visit the natural exhibition of the governmental forest service.
Savonlinna Cathedral
The cathedral is Savonlinna's main church, opened in 1879. The church had a bishop in the years 1896–1924 and hence gained the right to bear the name cathedral.
Little Church of Savonlinna (Pikkukirkko)
Built as an Orthodox church in 1846, transformed into a Lutheran church in 1938. The church was returned to the orthodox parish in 2022.
The Casino islands
Islands close to the city centre, a popular place among the locals for getting out in the nature. Hiking paths and places for swimming and barbecuing.
A nice way to see the city and its surroundings is from a small cruise ship. There are cruises of an hour or an hour and a half around the city or the surrounding archipelago, leaving every half an hour or so all day, some with old steamships, some with modern ships. Most have a café of sorts or even restaurant, some are accessible with wheelchair (not necessarily including the toilet). Some have multi-language commentary on the route. There are also longer cruises, even to Kuopio and Lappeenranta.
