The structure itself consists of the original, castle-like building, plus four wings that have been added during the intervening years, in styles ranging from Tudor Revival and Renaissance Revival to International. The museum is home to approximately 50,000 objects, including ancient Roman, Greek, and Egyptian bronzes; paintings from the Renaissance, Baroque, and French and American Impressionist eras, among others; 18th-century German and French porcelains (including Meissen and Sèvres); Hudson River School landscapes; early American clothing and decorations; early African-American art and historical artifacts; and more. The collections span more than 5,000 years of world history.
