I went to Sirucusa where one of my Italian friends live there. He drove to Catania everyday to work. In my opinion, I feel Sirucusa is more beautiful. There is a big old Roma theatre nearby.Catania seems too old and dark (bacause of the volcanic rocks that are used for building) to me.
By the way, how far is Agrigento away from Catania? I may go next time when I visit Catania again. Thanks for your posting.
