Once the imposing entrance to the Seaman-Drake estate, the arch, which is said to be a scale model of the Arc de Triomphe in Paris, is 35 feet tall and 20 feet deep and made of locally quarried Inwood marble. John Ferris Seaman bought 25 acres in Inwood in 1851 and created the estate and a mansion, also constructed of marble. The mansion was replaced in 1938 by the Park Terrace Gardens apartments.
