The Nassau County Museum of Art (NCMA) is located 20 mi (32 km) east of New York City on the former Frick "Clayton" Estate, a 145-acre (59 ha) property in Roslyn Harbor in the heart of Long Island’s Gold Coast. 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. In addition to the mansion, NCMA, which receives nearly 200,000 visitors each year, includes The Manes Family Art & Education Center, opened in 2017, as well as a Sculpture Park, a Formal Garden, rare specimen trees and marked walking trails.
