Founded as a not-for-profit in 1968 by philanthropist Doris Duke, the Newport Restoration Foundation (NRF) preserves, maintains, and interprets the early architectural heritage of Aquidneck Island and the fine and decorative arts collections of Doris Duke in Newport. Since its founding, NRF has restored and preserved more than 80 eighteenth- and early nineteenth-century buildings, 73 of which are currently rented as private residences to tenant stewards and maintained by a full-time crew of carpenters and painters. The NRF also owns and operates three museum properties: • Rough Point; Doris Duke’s Newport mansion; home to a large collection of European paintings, textiles, decorative arts and Asian ceramics with notable works by Van Dyck, Gainsborough, Reynolds, and Tiffany. Each year, a different themed exhibition is presented in its two formal galleries. • Whitehorne House; a Federal period brick mansion in the historic commercial district of Lower Thames, featuring one of the largest and most important collections of 18th-century Newport furniture in Rhode Island. • Prescott Farm; a 40-acre greenspace open to the public for free in Middletown, RI, with ties to the Revolutionary War and period gardens maintained by the University of Rhode Island's Master Gardeners.
