Senj is a kind of open-air gallery, with the centerpiece exhibit being the Nehaj, a sixteenth-century fortress of the Uskok warriors. Built to watch over the town, today it houses a collection of objects which attest the rich history of this region of heroes. Its battlements, where once the town guard had watch duty, are today an opportunity for you to enjoy the unforgettable views of islands and mountains which surround Senj.
The veiled secrets of Senj's past can be untangled in the former Vukasović family palace, now the Town museum, and also in the cathedral's treasury and library, where great troves of sacral heritage are held..
The front doors of many houses around Senj are decorated with sculptures of former family members. The central town square, known as the Cilnica, contains the old castle, rumored to be connected with the Nehaj fortress through an underground tunnel.
