Revelin Fort was built outside the city walls and is partially included into the defence complex of the Ploče Gate. The lower part of the fort was built in 1463, in the shape the City model held by St. Blaise on the triptych painted by Nikola Božidarević around 1500. The fort protected both the eastern part of the City from mainland and the entrance to the City Harbour.
In 1538 the fort was strengthened and enlarged in the form of an irregular square according to the instructions of Italian engineer Antonio Ferramolino of Bergamo. Revelin has three entrances, and was encompassed by the moat and sea on three sides. The well-known Renaissance craftsman Ivan Rabljanin kept the foundries for casting cannons and bells in the large Fort interior.
Today, the spacious fort terraces serve as venues for various performances of the Dubrovnik Summer Festival.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
