Beneath the M. Steinert and Sons piano store on Boylston Street in Boston lies a once-famous underground theater that has been abandoned and nearly forgotten for decades.

Steinert Hall was one of Boston's most famous concert venues in the early 20th century, and had the reputation as “headquarters for the musical and artistic world of cultured Boston” before it closed its doors due to safety regulations 70 years ago. In a recent feature on BuzzFeed, photographer Greig Lamont said the site has been abandoned for so long that most employees of the store are unaware of the 650-seat auditorium beneath their feet.

Although its structure is mostly intact, the hall has suffered massive water damage, making it unlikely this landmark will ever be restored to its former glory. Paul Murphy, president of Steinert and Sons, told the Boston Globe that repairs to the theater would cost around $6 million.
