In 1799, a prosperous New York merchant named Archibald Gracie built a country house overlooking a bend in the East River, five miles north of the City. Financial failure forced Gracie to sell his house to Joseph Foulke in 1823, and in 1857, the house came into the possession of Noah Wheaton. The City of New York appropriated the estate in 1896, incorporating its 11 acres of grounds into the newly-formed Carl Schurz Park. After decades of use as a concession stand and restrooms for the park, Gracie Mansion was restored and became the first home of the Museum of the City of New York. When it moved to a larger building, Gracie Mansion became a historic house museum run by the Parks Department. Parks Commissioner Robert Moses convinced City authorities to designate it as the official residence of the Mayor, and in 1942, Fiorello H. La Guardia moved in. The house was enlarged in 1966 with the addition of the Susan E. Wagner Wing, which includes a grand ballroom and two intimate reception rooms. The Gracie Mansion Conservancy was established in 1981, and under its guidance, the first major restoration was undertaken between 1981 and 1984.
