Alexandria

Alexandria, city, adjoining Arlington and Fairfax counties, northern Virginia, U.S. It lies on the Potomac River (there bridged at the Maryland state line), 6 miles (10 km) south of the District of Columbia. A fort was built on the site in 1676 to defend the area from attacks by Susquehannock (Susquehanna) Indians. The site was settled in the late 1600s, and a community known as Belhaven was founded there in 1731. English and Scottish merchants then established a tobacco warehouse in Belhaven, and the settlement soon became an important shipping centre. It was organized in 1749 and renamed for John Alexander, who had originally been granted the land, and in 1779 it was incorporated as a town. Alexandria has the unique distinction of being designated an independent city (without county affiliation) by an act of Congress (1852). George Washington helped to lay out its streets and drilled troops there during the French and Indian War.

From 1789 to 1846 Alexandria was part of the District of Columbia, after which it was ceded back to Virginia. Throughout the American Civil War (1861–65), Alexandria was occupied by Union troops. Its postwar development as a river port for shipping flour and tobacco was overshadowed by the growth of Baltimore, Maryland. Local trade and commerce were flourishing by World War I, when the Naval Torpedo Station was constructed there and the shipyards were reopened.

Although now mainly residential, Alexandria has large commercial and freight-rail operations and some manufactures (agricultural equipment, fertilizer, chemicals, lumber products). Many colonial-era buildings survive, some of which are associated with George Washington and with Henry (“Light-Horse Harry”) Lee, father of Robert E. Lee. Carlyle House (1752) was headquarters to British General Edward Braddock during the French and Indian War. Gadsby’s Tavern (c. 1785) and the adjacent City Hotel (1792), two buildings that were frequented by Washington, have been restored as a historic site and museum. The Alexandria Academy was established in 1785 and still exists. Washington, who maintained a house (now reconstructed) at Alexandria, served on the town council. Washington’s estate, Mount Vernon (9 miles [15 km] south), is a national historic landmark and contains his grave and that of his wife, Martha. The 330-foot (100-metre) George Washington Masonic National Monument (1923–32), modeled on an ancient Egyptian lighthouse, holds objects and relics owned by Washington. Pop.
