The William duPont Gallery in the Montpelier Visitor Center pays tribute to the legacy of members of another significant Montpelier family—William and Annie duPont, who owned the property for much of the 20th century. Their daughter, Marion duPont Scott, inherited the estate, which her heirs transferred to the National Trust for Historic Preservation in accordance with her will after her death in 1983. The Gallery displays objects and images related to the duPont’s tenure, during which the site’s equestrian heritage was established. The “Red Room,” a fully reinstalled exhibit of art deco furnishings and decor, showcases the only significant modification Mrs. Scott made to her parents’ home, which was substantially enlarged in the first decade of the 20th century.
