Teatro Tezzano

Teatro Tezzano is a fascinating slice of layered history right in the heart of Catania — a Roman theatre built in the first century CE directly on top of an earlier Greek structure, traces of which have only recently been uncovered. You're essentially looking at two civilizations stacked on top of each other, which makes it way more interesting than your average ancient ruin. It's an open-air semicircular space that still gives you a real sense of the scale and ambition of Roman public entertainment.
