The public is invited to visit and tour the towers and keepers house Saturday of 25 Maine lighthouses from Biddeford to Lubec during the third annual Maine Open Lighthouse Day.
This event is the largest of its kind in the country and is coordinated by the Coast Guard in partnership with the Maine Office of Tourism and the American Lighthouse Foundation.
Most of the 25 ocean, river and island lighthouses will be open to visitors from 9 a.m. to 3 p.m. for guided or self-guided tours. The list of participating lights can be seen at the Light House Day website.
Some lights that are not normally open to the public include Owls Head, Curtis Island in Camden Harbor, Dyce Head in Castine, Monhegan Island, Portland Breakwater and the tower at West Quoddy Head in Lubec. Some light stations might have limited accessibility or special restrictions.
"Open Lighthouse Day is a wonderful opportunity for the public to experience some of these important nautical landmarks in a way they may never have seen before," said Lt. Terence Leahy, of the Waterways Management Division in Sector Northern New England. "Even to this day, many lighthouses serve as navigational aids to keep mariners safe at sea."
