Dedicated to S. Agata, Catania’s patron saint, the Duomo was erected in the late 11th century at Roger I’s behest, rebuilt after the 1693’s earthquake. Its façade stands among Vaccarini’s masterpieces. Along via Vittorio Emanuele II, by the courtyard of the Bishop’s Palace, one can admire the tall lava apses, of Norman age. The cathedral’s solid-looking structure suggests that it was conceived as a fortified church. On the North side is a fine portal ornamented with an entablature with cherubs.
