Whitlocks Mill Lighthouse in Calais is on private property but can be viewed from the rest area on US Route 1 south of the Calais city center. The port of Calais used to be surrounded by heavy forests making navigation up the Saint Croix river difficult. Lighthouses were erected on the Canadian side of the river in 1857 but this light on the American side was only established in 1909. Prior to this a series of lanterns were hung in nearby trees. The St. Croix Historical Society applied for and was awarded ownership of Whitlocks Mill Lighthouse in 1997, as part of the Maine Lights Program. The Coast Guard still maintains the tower’s flashing green light. The three-bedroom, 2,428-square-foot keeper’s house and other outbuildings are privately owned and closed to the public. The dwelling sold in 2004, with an asking price of $350,000.
