In 1792, a group of Lisbon businessmen decided to finance the construction of a new Opera House in the city. The theatre was built in only six months following a design by Portuguese architect José da Costa e Silva, with neoclassical and rococo elements. The general project is clearly inspired by great Italian theatres like the San Carlo of Naples (interior) and La Scala in Milan (interior and façade). In the early 19th century, when the Portuguese Royal Court had to flee to the Portuguese colony of Brazil to escape the invading Napoleonic troops, a theatre modelled on the São Carlos was built in Rio de Janeiro.
