The Natural and Culturo-Historical Region of Kotor is a World Heritage Site located in Montenegro that was inscribed in 1979.

The old town of Kotor is contained within the city walls and a well preserved and restored medieval cityscape with notable buildings including the Cathedral of Saint Tryphon (built in 1166).

The fortifications consist of a system of defensive military buildings to protect the medieval town of Kotor.

While some of the structures date back to Roman and Byzantine times, most of the fortifications were erected during the Venetian rule; later some modifications were made by the Austrians.

Further the islets of St. George (Sveti Đorđe) and Our Lady of the Rocks (Gospa od Škrpijela) are part of the heritage site.
