Kotor is fortified medieval city situated at the deep and of the Boka bay (Boka kotorska). Kotor is largest of the old architectural entities in Montenegro. The city grew within a triangular area bordered by the hill, the sea, the river Skurda and Gurdic well. Inside the massive ramparts, the medieval plan has for the most part remained unchanged: narrow winding streets, and a great many squares faced by major architectural accents- church buildings and palaces.
The earliest archeologically registered building inside the old town is 6th century early- christian basilica, uncovered beneath the present day Church of Saint Mary Collegiate. This probably use to be cathedral church which supports the hypothesis that as early as in that century Kotor was large settlement and the sea of the bishopric.
In early 9th century the town got its patron saint- St Triphon, the whom memorial church was dedicated in 809 AD.
Evidence on intense urbanization has been kept since the 12th century. At that time 1166 new large cathedral was erected. Subsequently, number of Romanesque churches where built: St Luke's, St Mary Collegiate, St Anne's, St Paul's and other unpreserved ones. Gothic stile edifice include Drago palace and remains of the reconstructed Buca and Bizanti palaces; from that period there are also numerous remainders of architectural sculpture: doorways, three and two light windows, other relief decorations. Apart from the local architects, masons and sculptors, masters from other Adriatic cities, or now and then, from some foreign countries where commissioned to work in Kotor. The most notable among the others was Fra Vito, Franciscan friar from Kotor who build monastery of Decani in Serbia, major achievement of the day.
The baroque period left several churches( St Joseph's, Our Lady of the Angels, the Holy Spirit), palaces( Pima, Grubonja, Grgurina) and middle class mansions. Great many artifacts of both sacral and secular nature bore touch of that style too. It was mostly with imports from Venice that the local demand for works of painting and sculpture was met. The last large scale construction works inside the old center where undertaken during the Austro- Hungarian administration: towards the end 19th and 20th century, several public and private buildings were erected in the spirit of Secession, but they do not fit successfully in to the overall architectural milieu of the medieval Kotor.
Due to the authentic cultural and historical value of the city and its '' bridging '' role between Mediterranean and Balkan hinterland, Kotor has been entered on the Unesco list of natural and cultural heritage.
