National Trust Picks Most Endangered Places for 2011
The NTHP's site includes a map showing the location of each endangered place, and explains why those sites are at risk.
One of the most interesting sites on the list is Belmead-on-the-James in Powhatan County, Virginia:
"A little-known landmark of African American heritage, the 2,000-acre site along Virginia's James River was transformed by Saint Katherine Drexel from a slave-holding plantation into a pair of innovative schools for African American and Native American students. Closed in the 1970s, the historic buildings set in rolling hills and wooded glades of the riverfront campus, including a striking Gothic Revival manor house designed by Alexander Jackson Davis, are deteriorating and need emergency repairs."
