The oldest extant Roman monument in Verona dates from the time of Augustus, when the Arena was built and Verona was a strong Roman outpost at the crossroads of the Empire's ancient north-south, east-west highways. There is something almost surreal about attending an open-air performance of Shakespeare's Two Gentlemen of Verona or Romeo and Juliet here -- even if you can't understand a word. Classical music, ballet, and jazz performances are also given here, with evocative views of the city beyond. A small archaeological museum (same hours as the site itself) housed in a lovely old monastery is included in the ticket price. On Sunday (only), the promenade is open to the public.
