Roman Amphitheatre
Some modest remains amidst the square.
It's a centre of an ecclesiastical architecture in Catania: in no more than 200 m there are 4 churches, 3 monasteries and a college.
Walk the main shopping avenue, running north from the Piazza del Duomo has most of the city's imposing building and is busy throughout the day and evening. Lots of churches. This road is the equivalent of Las Ramblas in Barcelona, so in the evenings the local people put on their Sunday clothes and walk at a relaxed pace along this avenue.
Four Corners
Today the church used for various cultural events. Next to the church is a former Jesuit college.
