Founded by the Pilgrims on December 21, 1620, this town situated on the banks of Plymouth Bay is ripe with historical significance to U.S. history. Any American grade-schooler can tell you about Plymouth Rock and the Mayflower and here one can see both. The town has a replica of the famous ship, the Mayflower II at the state pier. From museums to the Plimouth Plantation, where history repeats itself daily, Plymouth is a fantastic place to explore.
