The Verona Arena is a Roman amphitheatre built in 1st century. It is still in use today and is internationally famous for the large-scale opera performances given there. It is one of the best preserved ancient structures of its kind. In ancient times, nearly 30,000 people was the housing capacity of the Arena.
The building itself was built in AD 30 on a site which was then beyond the city walls. The round façade of the building was originally composed of white and pink limestone from Valpolicella, but after a major earthquake in 1117, which almost completely destroyed the structure's outer ring, except for the so-called 'ala', the stone was quarried for re-use in other buildings. Nevertheless it impressed medieval visitors to the city, one of whom considered it to have been a labyrinth, without ingress or egress.
The first interventions to recover the arena's function as a theatre began during the Renaissance. Some operatic performances were later mounted in the building during the 1850s, owing to its outstanding acoustics. In 1913, operatic performances in the arena commenced in earnest due to the zeal and initiative of the Italian opera tenor Giovanni Zenatello and the impresario Ottone Rovato.
In recent times, the arena has also hosted several concerts of international rock and pop bands.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
