Napa Valley Opera House

The Napa Valley Opera House is a theatre in Napa, California, USA. It opened on February 13, 1880 with a production of Gilbert and Sullivan's HMS Pinafore. At the time, the town had a population of 5,000 people. The original owner was George Crowey and Charles Levansaler managed the facility.

The building was designed in the Italianate style by Newsom and Newsom, renowned architects of the 19th century, who also built the Carson Mansion in Eureka, California, in addition to many public and private buildings throughout the State. Construction of the theater featuring a stained glass skylight, brass chandeliers and a curved staircase leading to the balcony started in 1879. The building had stores and restaurants on the first floor while the stage occupied the second and third floor. The floor of the auditorium was uniquely constructed with a flat floor in order to accommodate local dances and pageants. The theater had an advertising curtain where local businesses were promoted.
