Preservationists have added some U.S. post offices and Texas courthouses to the list of the country's most endangered historic places.
Wednesday's announcement means post offices will join the list of America's 11 Most Endangered Historic Places as a group for the first time.
The National Trust for Historic Preservation is citing the bureaucratic process for disposing of thousands of aging post offices.
Another large group of sites being added to the endangered list includes the courthouses of Texas, with support from former first lady Laura Bush of Dallas.
The state's courthouses were first listed in 1998, but at least 70 of them still need critical repairs. According to the National Trust for Historic Preservation, 234 of the state's 244 county-owned historic courthouses are still in active government use.
Some 139 Texas courthouses are listed in the National Register of Historic Places and are built in a variety of styles from Art Deco to Romanesque.
