A wedding at the Audubon Society's Woodend Sanctuary combines elements of both city and country. Woodend is located inside the Beltway and features an elegant 1920s Georgian mansion designed by John Russell Pope, architect of the Jefferson Memorial. But Woodend also offers 40 acres of outdoor space, including a wildflower meadow, towering trees and sweeping lawns. Outdoor ceremonies often feature deer as surprise guests. Thanks to its association with the Audubon Society, Woodend is one of the most eco-friendly venues in the DC area, with a commitment to recycling, energy efficiency and even green cleaning. (And of course rental fees support the work of the Audubon Society itself.) Site fees, which range from $2,600 in winter to more than $10,000 for a day-long rental in summer and fall, include both indoor and outdoor spaces and a tented terrace. There's a list of approved caterers, but BYOB is allowed.
