Own a piece of Burlington’s History. 495 Colchester Avenue is located in an historic district and was built around 1840 using brick and post and beam construction for use as a Blacksmith and Wheelwright shop. It is currently thought to be the oldest industrial building in Burlington. At the turn of the 20th century, it was used as a grocery store and second hand store. In the years before World War I, the cellar housed a pool hall that was frequented by cavalry soldiers from nearby Fort Ethan Allen. In the aftermath of the historic flood of 1927, the road and bridge on Colchester Ave were raised, essentially encasing the ground floor in dirt and sand for nearly a 100 years.
