Ravenscry is a riverfront estate and hunting preserve on the Hudson River in Dutchess County, New York. It was the former residence of Cornelia Delamere Pendergast, great-aunt of Special Agent Pendergast, until her confinement to the Mount Mercy Hospital for the Criminally Insane. As part of reacclimating Constance Greene to the outside world, Pendergast began taking her on excursions to Ravenscry, which had sat abandoned since Cornelia Pendergast's commitment and had fallen into great disrepair.
