Theatre of the Four Fountains

The Teatro delle Quattro Fontane, also known as the Teatro Barberini, was an opera theatre in Rome, Italy, designed by Gian Lorenzo Bernini and built in 1632 by the Barberini family. From 1632 to 1637 it was located in a large room inside the Palazzo Barberini at the Quattro Fontane. In 1639, it was moved to a new, free-standing building, northeast of the palace and adjacent to the garden. By 1830, the theatre had closed, and the building was used for other purposes. It was demolished in 1932.
