Portland Breakwater Light 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 light sits in Bug Light Park in South Portland, where free parking is available. To reach the park, take Route 77 south into South Portland. Drive east on Broadway, turn left on Pickett St., which becomes Madison St. and leads to the park. Bug Light can also be seen from several Casco Bay cruises.
