The legendary address on Central Park is now part of Historic Hotels of America, a program of the National Trust for Historic Preservation that recognizes hotels for preserving and maintaining their historic integrity, architecture and ambiance. The Plaza Hotel-- the fictional setting for Kay Thompson's Eloise character-- isn't just a NYC landmark; the storied hotel looms large in the imaginations of folks across the United States. It's the only hotel in New York City listed as a National Historic Landmark on the National Register of Historic Places. After a $450 million, three-year renovation completed in 2008, The Plaza Hotel continues its tradition of luxury with a Caudalie Vinotherapie Spa, one-of-a-kind suites, and high-profile restaurants.
