Frankopan Castle, also known as Nova Kraljevica or Castle Zrinski, is a 17th-century fortification located on the Adriatic coast in Kraljevica, Croatia. It was constructed by Petar Zrinski and Fran Krsto Frankopan between 1650 and 1651 as part of a strategic defensive complex. The structure features a distinctive triangular floor plan with three towers connected by curtain walls and an inner courtyard. It sits overlooking the Bay of Bakar and the entrance to the Velebit Channel. Today, the castle serves as a cultural hub hosting local events, exhibitions, and municipal functions. The architecture reflects the transition from medieval defensive fortification to the Renaissance palatial style.
