National Historical Park and National Historic Landmark Establishment and Boundary Adjustments Act of 2025

This bill establishes the Fort Ontario Holocaust Refugee Shelter National Historical Park in New York to preserve the site where 982 WWII refugees were housed (1944-1946), requiring the Secretary of the Interior to first acquire sufficient land and publish a Federal Register notice. It also designates the America’s National Churchill Museum in Fulton, Missouri, as a National Historic Landmark, while mandating a 3-year federal study to evaluate its potential inclusion in the National Park System. The park will be managed under standard National Park System rules, with a requirement for a management plan within 3 years. The landmark designation does not alter local ownership or administration of the museum property.
