Thank you for partnering with us at The Leyden Preservation Group. Our goal is to preserve landmarks of historic significance that foster awareness of America’s national heritage. We seek to educate future generations on the legacy of America’s civil and religious liberty including a greater understanding of covenant, determination, and thanksgiving. To learn more about our upcoming events, and to access our latest resources, visit us at as we celebrate the 400th anniversary of the very first Thanksgiving (1621-2021).

Thanksgiving 400: A Grateful Nation

The American tradition of a special day of thanksgiving has as its foundation the Pilgrim harvest festivities of 1621. This year, 2021, marks the 400th anniversary of that celebration. Over the centuries millions of Americans have followed the example of the Pilgrims, with the result that Thanksgiving Day has become the great American tradition of American families stopping from work to celebrate and give thanks for the mercy and goodness of God.

The Enduring Legacy of the Mayflower Compact

The signing of the Mayflower Compact 400 years ago had far-reaching implications for all of society. What began in 1620 in Provincetown harbor would establish the American precedent of free men covenanting to maintain a “civil body politic” of self-government under God. It would culminate in the halls of Philadelphia in the 1780s with the formulation of the United States Constitution. To celebrate the 400th anniversary of America’s great covenant to liberty, the Leyden Preservation Group has created a beautiful, illustrated booklet that tells the story of The Mayflower Compact from its early history, to its legacy in law and government. This is the perfect read-aloud document for you and your family.

The Leyden Preservation Campaign

Project to Acquire Strategic Landmarks

33 Leyden Street

33 Leyden Street is designated on the National Register of Historic Places by the United States Department of the Interior. The property features a tablet erected by the Commonwealth of Massachusetts to mark the site of the first house built by the Pilgrims. In that house on February 27th, 1621, the right of popular suffrage was excersized and Myles Standish was chosen Captain by a majority vote. On or near this site, April 21, 1621, the memorable treaty with Massasoit was made.

Leyden Preservation Group intends to develop this site as a headquarters dedicated to:


To preserve historical sites that foster a greater understanding of the unique American identity which began in the experience of the Pilgrim Fathers and the settlement of Plymouth in 1620.


To promote the celebration of the 400th anniversary of the landing of the Pilgrims in 2020, by developing a national awareness of religious liberty of America.


To promote the legacy of Pilgrim principles of freedom and liberty worldwide. We are developing resources through media, guided tours and seminars to educate on religious and civil liberties for students and adults.

Site for future museum dedicated to Civil and Religious Liberty

We seek to acquire a strategically located site and convert it to a museum housing a multimedia exhibit and featuring state-of-the-art technology to present the story of the Pilgrims through narration, music, video, and printed material.
