Washington University in St. Louis seems ready to ignore pleas from the National Trust for Historic Preservation and follow-through with plans to tear down 105-year-old Prince Hall to make way for an underground parking garage. The university plans to begin demolition after commencement exercises in late May. Prince Hall is part of the Hilltop Campus Historic District, listed in the National Register of Historic Places in 1979 and designated a National Historic Landmark in 1987. School officials say it would be very difficult to renovated Prince Hall.
