Glen Rock Auditorium was constructed in 1913 as the community's opera house. The front facing Manchester Street is about as wide as the tightly packed neighboring houses, but a walk around back shows that the brick building extends all the way back to Pleasant Street which makes sense if the plan was to organize a stage and a large amount of seating to serve the public. From that vantage point one sees that there are three floors, a stone walled basement and two brick upper stories. A marquee in front is decorated with a large letter G facing front and GLEN written on each side. While the building is currently closed, a large historic plaque attached to the front reviews the building's connection with the local musical association, community groups, and the local high school. Movies as well as musical events took place at the auditorium. Hopefully talk of potential new owners and renovation into a community events center will bear fruit.
