The Nassau County Museum of Art (NCMA) is located on the former Frick "Clayton" Estate, a 145-acre (59 ha) property in Roslyn Harbor on the Gold Coast of Long Island, New York. The main museum building, named in honor of art collectors and philanthropists Arnold A. Saltzman and his wife Joan, is a three-story Georgian-style mansion that exemplifies Gold Coast architecture of the late 19th century.
