query: What is the oldest surviving opera house?
passage: Opera house
The first public opera house was the Teatro San Cassiano in Venice, opened in 1637. Italy is a country where opera has been popular through the centuries among ordinary people as well as wealthy patrons and it continues to have a large number of working opera houses[1] such as Teatro Massimo in Palermo (the biggest in Italy), Teatro di San Carlo in Naples (the world's oldest working opera house) and Teatro La Scala in Milan. In contrast, there was no opera house in London when Henry Purcell was composing and the first opera house in Germany was built in Hamburg in 1678.
passage: Bristol Old Vic
The Theatre Royal, the oldest continually-operating theatre in the English-speaking world, was built between 1764 and 1766 on King Street in Bristol. The Coopers' Hall, built 1743–44, was incorporated as the theatre's foyer during 1970–72. Together, they are designated a Grade I listed building by Historic England. Daniel Day-Lewis called it "the most beautiful theatre in England."
