Sweet-Briar-College-215x300RICHMOND, Va. (AP) _ Sweet Briar College is among Virginia’s most endangered historic places, according to a preservation group. The designation was announced Monday by Preservation Virginia in the 11th edition of its annual list of the state’s most-endangered historic places. Sweet Briar College announced in March it would close in August because of crushing financial challenges. The 114-year-old women’s college held what could be its final commencement over the weekend on its historic, 3,250-acre campus in the foothills of the Blue Ridge Mountains. The former plantation has 21 buildings on the National Register of Historic Places. The campus also includes a slave cemetery. Besides Sweet Briar, other endangered places include the Gibson Cottage at the Warm Springs Hotel and the town of Port Royal on the Rappahannock River.
