Mount Vernon — The Forgotten Heir

🎭Your Mission

You are Lawrence Lewis, George Washington's nephew, tasked in the early 19th century with uncovering a long-held family secret at Mount Vernon.

Your quest begins at the panoramic Overlook of

Uncover the past of Mount Vernon, Virginia, tracing a forgotten legacy from wartime fortifications to colonial estates.

The story that haunts this land

Your adventure in Mount Vernon begins on the George Washington Memorial Parkway, a 7,142-acre scenic parkway established in 1930 to connect Mount Vernon to Washington, D.C. This National Scenic Byway, designated in 2007, offers overlooks with views of the Potomac River. Near the Fort Hunt Overlook, you access trails that are integral to the Mount Vernon Trail system. It is here, facing the expanse of Virginia, that the first enigma sets you on the trail of secrets buried by your uncle, George Washington, the first President of the United States and owner of the famous Mount Vernon Estate.

The route then takes you to Fort Hunt Park, built in 1897 as Battery Rodgers during the Spanish-American War. Its two 12-inch guns could fire 1,000-pound shells over 12 miles. From 1942-1945, the site was used during World War II for secret coastal defenses and POW interrogations at Camp Hoffmann. Added to the National Register of Historic Places in 1974, Fort Hunt Park still features gun emplacements and underground magazines visible today. These military remnants, located near Alexandria, conceal clues that only a keen eye can decipher.

Walking alongside the Dyke Marsh Wildlife Preserve, a 1,235-acre tidal marsh preserve established in 1966, you discover the largest freshwater tidal marsh remaining in the urban Washington region, supporting over 350 bird species. Boardwalk trails accessible from the Mount Vernon Trail, part of the Potomac Heritage National Scenic Trail, offer an immersive break. This Mount Vernon Trail, an 18.4-mile multi-use trail opened in sections starting 1972, parallels the George Washington Parkway from Arlington to George Washington's Mount Vernon with an elevation change of only 400 feet. Over 2 million visitors use it annually, but few know the hidden messages along its banks.

Your quest leads you to Pohick Church, an Episcopal church constructed 1769-1774, attended by George Washington, who was a vestryman from 1762-1783, and George Mason. The only colonial-era church remaining in Fairfax County, its steeple was rebuilt in 1891 after hurricane damage. Washington's pew, with a family Bible from 1773, is preserved. Designated a Virginia Historic Landmark in 1968, Pohick Church is a key location where your uncle's legacy secrets might be inscribed in stone. Nearby, Woodlawn & Pope-Leighey House, properties managed by the National Park Service, reveal other chapters of Mount Vernon's history. Woodlawn, a plantation house built 1800-1802 by Lawrence Lewis himself on 2,000 acres gifted from the Mount Vernon estate, and the Pope-Leighey House, designed by Frank Lloyd Wright in 1940 and relocated to the site in 1964, illustrate architectural evolution and the life of Virginia's elite.

At the end of the journey, after exploring the Alexandria National Cemetery and the George Washington Masonic National Memorial, you will have assembled the puzzle pieces. This thematic circuit in Mount Vernon, Virginia, will have allowed you to visit major monuments and historic sites such as Fort Hunt Park, Pohick Church, and Woodlawn, all designated National Historic Landmarks or listed on the National Register of Historic Places. More than a simple visit to Mount Vernon, this exploration offers a deep understanding of the region's heritage, from key dates in the founding of the United States to personal narratives of the figures who shaped Virginia's history. You carry with you the feeling of having uncovered the mysteries of a forgotten legacy, revealing unexpected facets of American history.
