The Benedictine Monastery of San Nicolò l'Arena in Catania, Sicily, is one of the largest monasteries in Europe and the second biggest Benedictine monastery in Europe. The monastery was founded in 1558 and today it hosts the Department of Humanities of the University of Catania.
The monastery complex is located in the historical centre of the city of Catania, with the church of San Nicolò l'Arena. It shows architectonical integration of many styles through different centuries. Although the monastery was founded in the 16th century, it was modified by two natural disasters in the 17th century. In 1669 the 1669 Etna eruption surrounded the city of Catania, widening the coast for more than 1 km, and the monastery too. So the monastery was not destroyed by the lava but the area around was completely modified by a lava bench 12 meters high.
In 1693 the earthquake of Val di Noto destroyed the entire east coast of Sicily and Catania. The monastery was terribly damaged and the only floor that survived was the basement.
In 1702 the rebuilding started and lasted until 1866 (when the new Reign of Italy confiscated the monastery). The original monastery was rebuilt on the top of the latter, and they added a new cloister (the eastern cloister) and a new area (the large part designed by Giovanni Battista Vaccarini) on the top of the lava bench.
In 1977 the monastery was donated to the University of Catania, which restored the entire structure; in 1984 Giancarlo De Carlo started to design the entire restoration work.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
