The Diet of Porvoo refers to the historic 1809 assembly at Porvoo Cathedral, where Tsar Alexander I granted Finland autonomy as a Grand Duchy. This event is considered the birth of Finnish statehood. Visitors can stand in the cathedral nave where the oath was sworn and view commemorative plaques. The adjacent museum displays artifacts from the diet, including the throne used by the Tsar. The site is a pilgrimage for history enthusiasts seeking to understand Finland's national identity.
