Porvoo is one of Finland's six mediaeval towns, and in the Old Town, the district dating back to the time of Swedish rule, you can still sense the atmosphere of the mediaeval town.
The Old Town of Porvoo is unique. The mosaic-like town plan with its maze of streets and irregulary shaped plots dates back to the Middle Ages.
Since then the town suffered many fires, but always the stubborn citizens rebuilt their houses on the same foundations.
