Utö is a small island in the Finland Archipelago Sea. It is the southernmost year-round inhabited island in Finland. The written history of island dates back to the 16th century. Since the 17th century, it has been a base for pilots, lighthouse keepers, custom officials and soldiers.
The first lighthouse in Finland was built on Utö in 1753. The round lighthouse building was blown up during the Swedish-Russian war of 1808-1809. The present lighthouse was built in 1814 under the supervision of Chief Pilot Gustav Brodd. The lantern and the lights have been modernized several times. The present lens was installed in 1906.
Today Utö is popular place for a day trip. You can visit on lighthouse, a small museum and village with old wooden cottages.
The small Grisslehamn village is today a well-preserved sample of 19th century architecture and popular attraction for daily trips. The name Grisslehamn was first mentioned in a document from 1376 about the mail route between Sweden and Finland. This Grisslehamn was located some 20 km south of today's location. In the mid-18th century, most of the old village was destroyed in a fire, and it was decided to move Grisslehamn to its current location to make the mail route shorter. Conveying mail by row boat from Sweden to Åland, from whence it was transported to the Finnish mainland, was, together with fishing, one of the most important sources of income for the inhabitants of Grisslehamn and other parts of Roslagen for a long time, until steam ships took over the mail routes in the early 20th century.
During the Finnish War in 1809 a small unit of Russian cossacks attacked to Grisslehamn over the frozen Gulf of Bothnia. In the battle 80 Swedish soldiers surrended and several were killed.
Today there are several buildings dating from the 19th century, like the toll station and old barracks. The post office was built in 1755 and the chapel in 1909.
