Considered one of the nation's largest, most significant suburban art museums, Nassau County Museum of Art is located on the former Frick Estate, a 145-acre property. The main museum building, named in honor of art collectors and philanthropists Arnold and Joan Saltzman, is a three-story Georgian mansion that exemplifies Gold Coast architecture of the late 19th century. The museum's Sculpture Park is one of the largest publically-accessible sculpture gardens in the Northeast with approximately 40 outdoor works of art.
