This year’s list includes Threatt Filling Station and Family Farm, a Black-owned and -operated gas station along Route 66 in Oklahoma from the Jim Crow era, which was used as a safe haven for Black travelers, and its farm reportedly provided refuge to Black Oklahomans displaced by the Tulsa Race Massacre a century ago.

Also spotlighted is a Virginia school created by Julius Rosenwald to serve African Americans in the early 1900s, Pine Grove Elementary School. However, proposed construction of a landfill nearby threatens the school, which currently operates as a community center. In Maryland, Morningstar Tabernacle No.88 Order of Moses Cemetery and Hall join the list, which were established around 1885 near post-Emancipation Black settlement Gibson Grove. 

Other places in America’s Deep South are the Riverside Hotel in Clarksdale, Mississippi, which was one of the state’s only Black hotels and boarding homes in the Jim Crow era, and the former Georgia residence of Black midwife Beatrice Borders, who managed the building as a health facility for thousands of black women during the Jim Crow era. Also on the list this year are Alabama farms owned by African Americans who offered their properties as overnight campsites to civil rights marchers, including Dr. Martin Luther King Jr., Coretta Scott King, and Congressman John Lewis. They are located along the Selma to Montgomery National Historic Trail.

California sites honored on the list are the Trujillo Adobe, built in 1862 by Lorenzo Trujillo, a Native American who led expeditions across the Old Spanish Trail, enabling immigrants to settle inland California, as well as Summit Camp Site and tunnels, where thousands of Chinese railroad workers constructed the Transcontinental Railroad in the 1860s through the Sierra Nevada mountains.

Rounding out the National Trust’s 2021 endangered list are several places in the north: the Detroit home of civil rights activist Sarah E. Ray, and the Boston Harbor Islands—home to significant Native American archaeological finds and Fort Standish, used during World War II.

The annual list spotlights important places in the U.S.’s heritage from an architectural perspective that  could be damaged or lost indefinitely, without advocacy and action. Less than five percent of the more than 300 places highlighted by the National Trust have been lost. Placement on the list is “often the saving grace for important cultural landmarks,” according to a statement, and the first step in protecting such places. 

Last year’s list comprised places like SOM’s first hotel The Terrace Plaza Hotel in Cincinnati, Puerto Rico’s Ponce Historic Zone, and the historical Rassawek capital of the Monacan Indian Nation in Columbia, Virginia.
