The Boston Opera House, also known as the Citizens Bank Opera House, is a performing arts and esports venue located at 539 Washington St. in Boston, Massachusetts. It was originally built as the B.F. Keith Memorial Theatre, a movie palace in the Keith-Albee chain. The chain became part of RKO when it was established just before the theater opened on October 29, 1928, and it was also known as the RKO Keith's Theater. After operating for more than 50 years as a movie theater, it was rededicated in 1980 as a home for the Opera Company of Boston, which performed there until the opera company closed down in 1990 due to financial problems. The theater was reopened in 2004 after a major restoration, and it currently serves as the home of the Boston Ballet and also hosts touring Broadway shows.
