Built in 1795, the Alna School is one of the oldest extant purpose-built school buildings in New England. The small frame structure sits a short distance from the Old Alna Meetinghouse and is one of the finest 18th century buildings in town. The Federal period one-room school building features a square footprint with graceful cupola housing a bell projecting from the roof, which was added a few years after the building was completed. The school was one of two early school buildings for the newly incorporated town of Alna, soon after its separation from Pownalborough and incorporation in 1794 (originally as New Milford, and later at Alna in 1811). The school remained in operation through the 20th century and is no longer used.
