Arena romana – Arena di Verona, built in the 1st century AD, the fourth largest Roman theatre in Italy, capable of holding about 30,000 spectators (Bolla 24). It was originally used for shows of gladiators and fighting animals, then later for plays, opera, bullfights, and political events. The theatre originally had three tiers of galleries, but the third tier, the highest, was demolished to provide stone for the city wall in the time of Theodoric (r. Italy 493-526). (Bolla 13.)
