Uspenski Cathedral
Uspenskin katedraali
A classical and prominent onion-domed Russian church, the largest Orthodox church in Western Europe, Uspenski Cathedral serves Finland's small Orthodox minority. The name comes from the Russian uspenie, from the Dormition (death) of the Virgin Mary. The five domes are topped with 22-carat gold, and some of the icons within are held to be miraculous.

Market Square
Kauppatori
At the end of Esplanadi facing the sea, this open-air market sells fresh fish and produce from all over Finland. Open year round. It's busiest in summer, although the Christmas Market in December is also worth a look. One section of the market is devoted to souvenirs, but best buys here are the fresh berries and other produce. In summer, try the sweet green peas (herne). Pop open the pod and eat as is.
