Fodor's Expert Review Fortress of St. Nicholas

Standing at the entrance of Šibenik's St. Anthony's Channel, the Fortress of St. Nicholas sits on the islet of Ljuljevac and is an imposing Renaissance-era Venetian-style building. Constructed in 1540, the fortress was added to the UNESCO World Heritage list in 2017. It is definitely worth a visit from land—or better yet, from the sea via kayak.
