The Bacon Academy, nicknamed Old Bacon Academy, was the original Bacon Academy. The Old Bacon Academy was built in 1803 and is located at 84 Main Street, Colchester, Connecticut. The main structure is a 70 feet (21 m) long by 34 feet (10 m) wide three-story Flemish bond brick structure with Federal style details. Noted for its plain, utilitarian floor plan consisting of two rooms off a central hall and stairway, the inside has seen some renovations throughout its history. The Day Hall, a contributing property purchased by the Bacon Academy trustees in 1929, is a church hall that was used for the high school until 1962.
