Program accomplishments

  • Education Programs The Portsmouth Historical Society offers a wide range of educational programs designed to connect learners of all ages with local history through hands-on, inquiry-based experiences. In 2024, the Society expanded its offerings to include a monthly homeschool program in response to strong community demand. These programs emphasize critical thinking, curiosity, and engagement with primary sources, helping students explore how history shapes our present and future. Alongside school and group visits, walking tours, and special programs for families, this educational expansion has resulted in significant growth in participation and deepened connections to the organization's mission of inspiring lifelong learning through history.

These initiatives also include lectures, public forums, and collaborations with local and state partners to advance preservation awareness and policy. As part of the Society's new strategic plan, these efforts continue to strengthen community stewardship of Portsmouth's built environment and its shared history.
