The emblem of the historical sites managed by MetsähallitusIn the peaceful Iso Linnamäki park high above the bustle of central Porvoo, it is difficult to imagine that this was the scene of fierce battles during the Great Northern War in the 1700s. Half a millennium before then, a castle dominating the entire Porvoo river valley stood on this site. It was probably built by the Swedes during their conquest of the east. The steep-walled moats circling the top of Linnamäki hill bear witness to the past. When examining the landscape, you can understand very well why ancient chieftains chose this hill as their refuge.
