Mosby's Landing is now a Piggy-Back Townhouse condominium, Vienna, VA 22181, about 250-275 units. Property is actually about 1500 feet outside of the Town of Vienna, VA in Fairfax County, VA. The farm and farmhouse called Contemplation was demolished when the condo was built circa 1975. There are still two gravestones at the rear of the property dating from the farm. According to local history books, Mosby may have staid (hid) overnight at the farm house. The property is located about 2 miles from a minor US Civil War battlesite along the Washington and Old Dominion Railroad Line (now a bicycle path and utility corridor). The property borders Chain Bridge Road (Route 123); Union troops came from Washington, DC over Chain Bridge and must have passed by the property on the way to and from Bull Run (1st Mananasas).
