Though decades ago it was a concert space for some of the world's most notable classical musicians, a hidden theater once called Steinert Hall on Boston's Boylston Street has long been forgotten.
Steinert Hall is located deep below M. Steinert & Sons, a piano store on "piano row" across the street from Boston Common.
Photographer Greig Lamont told BuzzFeed that after a visit in 2011, he learned the theater was so infrequently visited that employees who had worked for the shop for ten years had rarely seen it.
Steinert Hall recently came back into the public attention when a reporter for Emerson College's radio station stumbled upon it while working on a different story.
