1) The Salem Witch Museum brings you back to Salem of 1692 for a dramatic overview of the Witch Trials, including stage sets with life-size figures, lighting and a narration. There is also a possibility to go on a candlelight tour to four selected homes. The museum is open all year round and closed on Thanksgiving, Christmas and New Year’s Day. Salem is also famous for its Haunted Happenings, a 24-day Halloween festival.
2) The Discover Sea Shipwreck Museum opened its doors in 1995, and has one of the largest collections of shipwreck and recovered artifacts in the Mid-Atlantic.

3) The Seashore Trolley Museum is the oldest and largest electric railway museum in the world. It was founded in 1939 with one open trolley car, No. 31 from the Biddeford & Saco Railroad Company.

Visitors can even take a trip along the Maine countryside aboard a restored early-1900s electric streetcar.
