In Hudson Valley Ruins: Forgotten Landmarks of an American Landscape, preservationists Thomas E. Rinaldi and Robert J. Yasinsac share their fascination with the dozens of once grand-but now abandoned-buildings and sites that dot the Hudson River landscape. Enhanced with hundreds of telling black and white photographs, the book describes the historical and architectural significance of the ruins, which range from majestic river estates to the former factories, while capturing the flavor of a bygone era.
