WASHINGTON (AP) -- A major slave-trading center from the 19th century and two architectural gems in Cincinnati are joining a list of the nation's most endangered historic places.
The National Trust for Historic Preservation released its listing of America's 11 Most Endangered Historic Places on Monday. It includes sites from Virginia to Hawaii.
Preservationists say a major slave-trading center in the one-time Confederate capital of Richmond, Virginia, is threatened by potential development of a minor league ballpark. The Shockoe Bottom area was home to Solomon Northup's jail, featured in the film "12 Years a Slave," and still contains underground artifacts.
For the first time, the list includes two sites from the same city: Cincinnati's symbolic Art Deco Union Terminal and its Music Hall. Both sites need extensive repairs.
Here's a look at the list, through photos.
