Verona Arena

An enormous, spectacular Roman amphitheatre, crumbling on the outside but still in use today. It was erected in the 1st century AD in an elliptical shape, and is the world's third-largest amphitheatre to survive from antiquity. The outer wall fell down during the earthquake of 1117, except for a small section locally called the "Ala" or wing, and enterprising citizens used the rubble to build houses on the back of the structure. What you see today is the masonry supporting the tiered interior. Catch an opera here if you possibly can, but you'll need to book months ahead. There's another smaller amphitheatre across the river, see below.
