Verona's epicentre is Piazza Bra with its Roman coliseum known simply as the Arena. The world's largest opera house, the 22,000 seat amphitheatre is still in use today during Verona's world famous Opera Festival. Elsewhere in the ancient city the Piazza dell Erbe is a feast of medieval architecture, containing several of Verona's distinctive "fish-tail" topped buildings, as well as baroque and classical styles. Just off the square you can see the house of the Capulets, where tourists gather under the balcony where Romeo professed his love to his Juliet. The Loggia del Consiglio in the Piazza dei Signori is a fabulous example of Renaissance architecture, while the city cathedral combines Gothic motifs with Romanesque and Renaissance features. The 14th-century castle and its fortified bridge on the edge of the old city meanwhile, towers over the city.
