Beautifully designed church with elaborately decorated floor. We stopped in because there was a service going on at the adjacent cathedral and glad that we did; otherwise, given all the other churches in Catania that we were planning on seeing, we might have missed it. That really has been our experience in our trip to this part of Sicily - to choose what we want to see and to plan the time to do so. We haven't taken any city tours - our planning is basically TripAdvisor reviews and guidebooks - but we have also been surprised on several occasions to just drop in to a place not in our plan and find it quite interesting. Fortunately, many of the cities we have been in - Scicli, Noto, and Syracuse - have been pedestrian friendly, so there have been opportunities to simply walk by something unplanned.
