10 minutes walk from the Cathedral square you find the Monastery of San Nicolò l’Arena, a late baroque monument and one of the biggest Benedictine monastery in Europe. The construction of the building started in 1500 and has continued until today. It is an example of architectonical integration of different styles through different epochs: you can find a roman house, the cloisters and a roof garden. The monastery is a UNESCO World Heritage Site. It hosts the Department of Humanities of the University of Catania.
