The Peirce - du Pont House
Longwood Heritage Exhibit
The Peirce-du Pont House takes its name from the two families who lived here for a combined total of over 200 years. When Pierre S. du Pont acquired Longwood from the Peirce family in 1906, his purchase included their early 18th-century farmhouse (the porch section of the house to your right). He built an L-shaped addition onto the original Peirce farmhouse in 1914, doubling the size of this home. Connecting the old and new wings was Longwood's first conservatory, which was luxuriously planted with exotic folliage and designed as an enclosed garden living room.
We invite you to enter Mr. du Pont's house and explore Longwood's beauty and history.
Mr. du Pont's successful experience with this unique greenhouse inspired him to construct the much grander Conservatory complex.
