Windsor Hotel, ca. 1885.

The Windsor Hotel, which occupied the entire blockfront on the east side of Fifth Avenue between 46th and 47th Streets, was hotel for a new kind of neighborhood. Construction on the seven-story hotel began in 1871, the same year the Grand Central Depot opened a few blocks away. The lots on Fifth Avenue between 42nd Street and 50th Street (where St. Patrick's Cathedral would rise in 1878) were being transformed from simple wood-frame structures, open spaces, and natural features like ponds, into a neighborhood of wealthy residents. When the hotel opened in 1873, it catered to this affluent sect. It was referred to in a late 19th century book as “at that time, the most luxurious and aristocratic hostelry in New York.”
