The Hagley Museum and Library is a nonprofit educational institution in unincorporated New Castle County, Delaware, near Wilmington. Covering more than 235 acres (95 ha) along the banks of the Brandywine Creek, the museum and grounds include the first du Pont family home and garden in the United States, the powder yards, and a 19th-century machine shop. On the hillside below the mansion lies a Renaissance Revival garden, with terraces and statuary, created in the 1920s by Louise Evelina du Pont Crowninshield (1877–1958).
