The Renwick Ruin: New York's Only Landmarked Ruin
The Smallpox Hospital on Roosevelt Island was the first major U.S. hospital dedicated to smallpox care, treating roughly 7,000 patients from 1856 to 1875. Designed by James Renwick Jr. in Gothic Revival style, the roofless granite shell is now New York City's only landmarked ruin — viewable from Southpoint Park and FDR Four Freedoms Park.
