One of the most powerful cities during the early rule of the Roman Empire, the old city of Verona is one of the best-preserved sections in the country. The city is the well known setting of Romeo and Juliet. The Arena di Verona is the third largest arena in Italy, and should not be missed by anyone sightseeing in Verona, Italy. Despite being constructed in 30 AD, much of the original architecture remains, and the amphitheater still houses opera productions throughout the summer.
