The town received its name from a Swedish medieval fortress near the river Porvoonjoki, which flows through the town.
Porvoo is a city and a municipality situated on the southern coast of Finland.
The Porvoo Old Town is a popular tourist destination, known for its well-preserved 18th and 19th-century buildings and 15th-century cathedral, the Porvoo Cathedral.
The name Porvoo is the Fennicised version of the Swedish name (Borgå) and its parts of borg, meaning “castle”, and å, “river”.
Porvoo is twinned with the following cities: Dinkelsbühl, Germany; Dalvíkurbyggð, Iceland; Hamar, Norway; Hancock, Michigan, United States; Lund, Sweden; Kamień Pomorski, Poland; Viimsi, Estonia; Viljandi, Estonia & Viborg, Denmark.
In the 1967 British-American espionage film Billion Dollar Brain, a small part of the plot takes place in Riga, the capital of Latvia, which is actually filmed in Porvoo. Also the 1997 American film The Jackal features scenes depicting Russia, which are partly shot in Porvoo.
The area where Porvoo today lies is first inhabited with the arrival of Swedish settlers.
Six cities were established in Finland in the Middle Ages. Porvoo, on the coast of the Uusimaa region, was one of them; it was granted the Town Charter around 1380.
The city of Porvoo and the surrounding municipality of Porvoon maalaiskunta are merged on 1 January 1997. The merge had been discussed for a long time, both officially and unofficially. The new municipality is named City of Porvoo.
