Catania Cathedral is dedicated to Saint Agatha and it is a Roman Catholic cathedral in the city center of Catania.

The current appearance of the cathedral dates from the work in 1734-1761 of Gian Battista Vaccarini, who designed the Baroque façade. The cathedral has been destroyed and rebuilt several times because of earthquakes and eruptions of the nearby Mount Etna.

It was originally constructed in 1078-1093, on the ruins of the ancient Roman Achillean Baths, by order of Roger I of Sicily and it was destroyed for the last time 1693 by the earthquake of Val Di Noto.

The holy ceremonies dedicated to Saint Agatha take place every 3d, 4th, 5th of February and 17th August.
