Hill-Stead, now a museum, was created on 250 acres (1.0 km²) of Farmington Mountain as a country estate for wealthy industrialist Alfred Atmore Pope, to the designs of his daughter Theodate Pope Riddle in 1901.
Theodate inherited the house after her parents deaths, and prior to her own passing in 1946 willed Hill-Stead Museum as a memorial to her parents.
She directed that both house and its contents remain intact, not to be moved, lent, or sold.

Hill-Stead comprises 152 acres (0.62 km²).
 Buildings include the 33,000-square-foot (3,100 m²) Colonial-Revival style Pope-Riddle House; an 18th-century farm house; a carriage garage with an Arts and Crafts theater; and a barn and additional farm buildings.
The house is extensively furnished with paintings, prints, and art.
Highlights include works by Édouard Manet, Claude Monet,  James McNeill Whistler, Albrecht Dürer and postcards including correspondence from Mary Cassatt, Henry James, and James McNeill Whistler.
