Welcome to Pilgrim Hall Museum! The Pilgrim Society was founded in 1820 to preserve Plymouth’s unique history, and in 1824, opened the doors of Pilgrim Hall Museum to the public. It is the oldest continuously operating public museum in the country and America’s museum of Pilgrim possessions. Pilgrim Hall’s extraordinary collection of 17th century artifacts, some of which actually came on the Mayflower, illuminates the story of early Plymouth Colony. It’s an intimate story of families, of differing cultures, and of courage in the face of great difficulties. In many ways, it’s the story of the founding of America.
