The Church of St. Nikola, or Crkva Sv. Nikole, as it is called in Serbo-Croatian, is located in the center of town. Inside the chapel are surprisingly well preserved sculptures of angels.
There is no charge to enter the church, but you will have to pay a small fee to climb the bell tower next to the church.
For all its defensive battles, Perast had only one small fortress on the side of the hill above the town. The fortress, Sveti Kritz, was built during the 16th century. This little fortress was used to defend the town against the Turks.
