Portland is essentially a craggy island joined to the mainland by the long sweep of Chesil Beach. Its unique white limestone has been here for centuries and has found its way into many of the world’s finest buildings, including the British Museum, St. Paul’s Cathedral, and the UN Headquarters in New York. The views from the rugged cliff tops area amazing, especially around the lighthouse. You can climb the 41 meter high tower for more great views of the area. Portland Castle is one of the finest examples of defensive castles built during Henry VIII’s castle building spree. You can try on period armor here and get more fantastic views over Portland’s harbor. The Portland Museum is housed in two thatched cottages overlooking Church Ope Cove, and has a variety of displays exploring the town’s history, especially its history for smuggling and shipwrecks. There are also some huge fossils collected from the nearby Jurassic Coast. The museum’s first curator was Dr. Marie Stopes, who invented the birth control pill.
