Of the hundreds of ships that made the transatlantic crossing in the 1600s, the Mayflower is the ship we remember. Three hundred years later, on June 13, 1957, a full-scale reproduction arrived in Plymouth Harbor, Mayflower II. Since then, Mayflower II has become the majestic centerpiece of historic Plymouth Harbor, and the Commonwealth of Massachusetts. More than twenty-five million people have stepped aboard her decks to imagine the perils and contemplate the modern impacts of the historic crossing. Today, Mayflower II is a floating classroom and working vessel. Following her restoration and return to Plymouth in 2020, she was added to the National Register of Historic Places, illuminating that she is a historic ship in her own right.
