It's one of the best church in Catania, with fantastic decoration. It's the church of a monastery of cloistered nuns (Monache Benedettine dell'adorazione perpetua del Santissimo Sacramento di Catania). The first church was build mid XIV sec. The actual monumental treasure was build after the 1693 earthquake, and completed in late 1700s.
The church is in via Crociferi, a rich street full of baroque architecture churches, a treasure protected by Unesco (World Heritage List).
The morning on Feb 6, there is the nuns choir in honor of Saint'Agata.
