The remains of the Church of St. John the Baptist are situated in Svač near the city of Ulcinj. Some researchers have suggested that this edifice could have been built by the Serbian King Stefan Uroš II Milutin (reigned 1282-1321) around 1300, although there is insufficient evidence to support this assumption. The preserved Latin inscription on the Western façade, South of the door, testifies that the Church was built in 1300 (MCCC), for the catholics.
It is a single nave edifice with a semicircular apse. Later, above the apse a tower was built marking this edifice as a Cathedral Church. To this type of building belongs also a Church of St. John in Raša in Albania.
The concept and dimensions of the basic space of the Church include the possibility of the influence of the architecture of the first buildings of the Franciscans and Dominicans in medieval Serbia, which would correspond to the end of the 13th century (1300 AD).
