OVERVIEW
An hour outside Washington, this 500-acre estate was founded in 1725. The space now holds a large equestrian center and provides lessons for private events in an indoor arena (which also has seating for 300) or on outside trails. Other banquet facilities include the 3,000-square-foot Ripley Hall and a tented outdoor lawn for 100. The estate also offers swimming, hiking, canoeing, and golfing facilities.
