In the western part of modern Kaštel Lukšić Mihovil Rosani built his castle in 1482. This is an obvious example that castles were built on the sea reefs. There was a small village around Rušinac, which was abandoned due to security reasons. The church of St. Ivan is there.
Nikola i Jerolim Vitturi, noblemen from Trogir, get the doge's permission to build a castle by the sea in order to protect their families and peasants of the Ostrog village on the Balovan reef. The castle was completed as a lavish palace in 1564.
Beneath Kozjak, on the Balavan ridge (259 m) there is the church of St. Lovre od Ostroga. Ostrog was a village where didići (free peasants working on their own land) had their centre. This village was first mentioned in 1171. The settlement was built on remains of Roman and Illyrian settlements. The church of St. Ivan Biranj (637 m) was built at the highest part of the western Kozjak where an Illyrian fort once was.
