Opened: 1856. The three story Maguire's Opera House was the first San Francisco theatre built with the intention of housing grand opera with its big stage, a large pit, and good rigging. Although the house was supposedly dedicated to opera they also ran minstrel shows, burlesque, farce, and melodrama.
Closing: The theatre was demolished in 1873 for street construction -- the pushing through of Columbus Ave., then called Montgomery Ave.  The nearby Metropolitan Theatre on Montgomery St. was also lost to the street project.   Source: San Francisco Theaters
