The Raseborg castle ruins, situated on a rock by the river
Raseborg, are the remainders of a castle that was probably built in
the 14th century, when the rock was still surrounded by water.
Raseborg is officially mentioned for the first time in a letter
dated 1378. It is a typical medieval castle of a simpler kind that
has been constructed during a long time period. There is no other
similar castle in Finland.
