Portland Head Light: Maine's oldest lighthouse, built during George Washington's presidency, is located on the shores of Cape Elizabeth. Originally, the 80-ft. tower was lit with 16 whale-oil lamps. Today there are a number of interpretive displays at the onsite museum (1000 Shore Road).

Portland Observatory: Climb the 103 steps to the top and enjoy the views of Portland and Casco Bay. This signal tower is the only remaining wooden maritime signal station in the U.S. It was built in 1807 and is currently listed on the National Landmark Registry (138 Congress Street).

Victoria Mansion: Originally built in 1858 for a wealthy New Orleans hotelier, the Italian villa-style mansion has graceful verandahs, a four-story tower and a lavish interior.

Visitors can tour the property, which still boasts 90 percent of its original contents such as gas light fixtures, elaborate wall paintings and exquisite woodwork (109 Danforth Street).

Visitors can explore the small district of art galleries, seafood restaurants and souvenir shops.
