Bug Light Park is home to Portland Breakwater Lighthouse and the Liberty Ship Memorial. Bug Light Park, the eastern terminus of the Greenbelt Walkway, offers expansive views of Portland Harbor and the skyline of Maines largest city. The nearly 9 acre park was the site of major shipbuilding activity during WWII. An estimated 30,000 people were employed here from 1941-1945 building liberty ships for the New England Shipbuilding Corp. and the South Portland Shipbuilding Corp. Although far less bustling today, Bug Light Park is a popular destination for picnicking, boating and kite flying. A busy boat launching area (seasonal fees required) and a liberty ship memorial are at opposite ends of the park. In between is a paved walkway along the shore and out to Bug Light itself. Portland Breakwater Lighthouse was built in 1875 and is one of Maine's most elegant lighthouses. Though modeled on an ancient Greek monument, it was built with plates of cast iron. It was dubbed "Bug Light" due to its small size. The South Portland Historical Society and Museum can be found near the entrance to Bug Light Park.
