What to see: St Lucas’ Church, St Nicholas’ Church, Treasury of SOC in Kotor, Music School, Lombardic Palace
St Lucas’ Church: It was built in 1195 by Mauro Kacafrangi. It is an excellent example of Romanesque and Byzantine style. Next to the northern wall of St Lucas, a chapel of St Spiridon was built at the end of the 18th century. The importance of this church comes from being a house for both the Orthodox and the Catholic altar during the invasion of the Ottomans. Today it’s a Serbian Orthodox church.
St Nicholas’ Church: It took seven years to build the church, from 1902 to 1909. There used to be the Dominican monastery of St Nicholas in 1540 on the area where the church was built.
Treasury of SOC in Kotor: It is located just next to St Nicholas Church. Archived documents, handwritten and early printed books are exhibited in here.
