The Winterthur Story

Welcome to Winterthur! Founded by Henry Francis du Pont, Winterthur (pronounced “winter-tour”) is an American Treasure. Regarded as one of America’s most beautiful historic homes and mansions, on par with Biltmore Estate, Monticello, and Hearst Castle, visitors marvel at du Pont’s elegantly-furnished 175-room former home. Winterthur’s 60-acre garden is considered one of this nation’s great gardens, and its research library serves scholars from around the world. We invite you to explore Winterthur’s beauty and history.
