Jones Point Lighthouse

The Jones Point Lighthouse is one of the last riverine lighthouses in the country and the only one still standing in the Chesapeake Bay area. Today it is the focal point of Jones Point Park and a clue to area's history as a busy commercial center and naval base.

Creation and Construction

The lighthouse operated from 1856-1926. It was designed as a navigational aid to help ships avoid shifting underwater shoals on the Potomac River and to support the growing maritime economies of Alexandria, Virginia and Washington, D.C. It had a fifth order Fresnel lens, the most advanced lens technology available in the 1800s, and produced a light beam which could be seen nine miles away. It was very useful to the hundreds of merchant, passenger, fishing, and naval vessels that traveled the Potomac each day.


Lighthouse Life

The lighthouse usually had a keeper and an attendant appointed by the president to ensure year round operation. The lighthouse employees had many duties besides keeping the beacon lit 24 hours a day. They maintained the building itself and kept records of shipping traffic, weather, and tides. They worked long hours for low pay and rarely traveled far from their station.

However, keepers did get to live in the lighthouse for free. For unmarried keepers, the four-room lighthouse provided plenty of space, but for men with families the house could become very cramped. Benjamin Greenwood, the longest serving keeper, lived with his second wife and 11 of his 14 children in the building at one point.

While the lighthouse was physically separated from Alexandria in the 1800s, the keeper and his family were never short of visitors. As the city grew, its factories, rail yards, docks, and storehouses created a very prosperous, but also very noisy, smelly, and congested industrial center. The lighthouse's scenic shoreline made it a favorite recreation spot for Alexandrians. People would visit Jones Point each weekend to picnic, fish, swim, and relax along the banks of the Potomac.

Decommission and Salvation

In 1918 a massive shipyard was constructed at Jones Point to build ships for WWI. The shipyard obscured the lighthouse's beacon light, making it less useful as a navigational aid. In 1926 an automated light tower replaced the manned lighthouse to cut costs. The lighthouse was deeded to the Mount Vernon Chapter of the Daughters of the American Revolution (DAR) who maintained the structure as a museum until 1936 when the Army Signal Corps built a classified communication facility on the former shipyard and closed it to the public. In 1953 the Army reopened Jones Point to public entry, but significant damage to the lighthouse from weather, tides, and vandalism had occurred, soldiers even using the building for target practice during WWII.

After the Army allowed the public to enter Jones Point again in 1953 the damage to the lighthouse only accelerated.  Vandals repeatedly defaced the building, looted it for artifacts and materials, and even set fire to it.  The DAR chose to transfer the property back to the federal government to ensure that the historic structure was not completely destroyed.

Lacking money to repair the lighthouse, the DAR worked with the National Park Service to establish a park on the site and restore the lighthouse. In 1964 Jones Point Park opened and for the past sixty years, Jones Point Park has been an area of recreational usage for thousands of people in the DMV.
