In the fruitful Kostel valley, the old Croatian nobles Keglević owned estates and castles: Bežanec, Dubrava and Gorica, as well as the old medieval Kostelgrad above Pregrada. Gorica Castle is a late Renaissance castle built in the late 16th century when uncomfortable and old medieval towns on the tops of hills are abandoned and castles are built in the lowlands. The park area next to the Gorica Castle consists of a landscape park formed of a wild forest of sessile oak and hornbeam, which was created during the 19th century. A special feature of the park is the lake with an islet, known as the “Island of Love”. The entrance to the castle is along the lake and the southern part of the park, but the whole park is separated from the castle, which is a rare example of such park location. Today, Lake Gorica is managed by the Gorica Sport Fishing Association.
