Fort Vrmac is a former fortification of the Austro-Hungarian Empire located on the southern end of the Vrmac ridge near Tivat. Established in 1860, the present structure was built between 1894 and 1897, and saw action during the First World War, when it was heavily bombarded by the Montenegrins. It was repaired and disarmed before the end of the war and was abandoned after a period of occupation by Yugoslav troops. Today it is one of the best preserved Austro-Hungarian fortifications in the Bay of Kotor area.
The fort comprises a heavily reinforced stone and concrete structure situated within a ditch, defended by three caponiers. There is a single entrance on the north side, accessed from the ditch and protected by a caponier. The design is similar to that of the 'Vogl period' fortresses in South Tyrol, with an irregular pentagonal shape constructed on two levels. The main guns were housed in armoured casemates, with howitzers and observation turrets in steel cupolas made by Škoda in Pilsen.
The roof of the fort is a 1.5 m thick slab of concrete that was installed in 1906–1907 following improvements to Montenegrin artillery capabilities. The barracks rooms are located on the ground and first floors on the north side while the casemates are situated on the other sides of the fort, facing towards what was then potentially hostile territory. A separate structure a short distance to the north of the fort was used as an ammunition magazine.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
