Porvoo is a city and a municipality situated on the southern coast of Finland approximately 50 kilometres (30 mi) east of Helsinki. Porvoo is one of the six medieval towns in Finland, first mentioned as a city in texts from 14th century. Porvoo is the seat of the Swedish speaking Diocese of BorgÄ of the Evangelical Lutheran Church of Finland.
At this time, Porvoo was the second largest city in Finland. After the conquest of Finland by Russian armies in 1808 Sweden had to cede Finland to Russia in 1809 (the Treaty of Fredrikshamn). The Diet of Porvoo in 1809 was a landmark in the History of Finland. The Tsar Alexander I confirmed the new Finnish constitution (which was essentially the Swedish constitution from 1772), and made Finland an autonomous Grand Duchy.
The Porvoo Common Statement is a report issued at the conclusion of theological conversations by official representatives of four Anglican Churches and eight Nordic and Baltic Lutheran Churches in 1989–1992. It established the Porvoo Communion, so named after the Porvoo Cathedral where the Eucharist was celebrated on the final Sunday of the conversations leading to the Statement.
