The new London Town Visitor Center + Museum includes educational exhibit spaces, an archeology laboratory, and instruction facilities that provide a place where the history, archaeology, preservation, and horticulture programs can interact. The center was built in a former underground waste water treatment plant to environmentally and archaeologically limit site disturbance. The reception area in this building is the start and finish control point for all public visits to the site, including visits to the William Brown House, a National Historic Landmark.
