The Stone Bridge is a bridge over the Bull Run in Manassas, Virginia, originally built in 1825. The Stone Bridge was an early focal point of the first major engagement of the Civil War: the First Battle of Manassas. The "historic first shot" was fired over this bridge in the early morning of July 21, 1861. Later in the war, the bridge was heavily damaged, but it was rebuilt after the war according to its original design. Today the Stone Bridge is a popular site for visitors to the Manassas National Battlefield Park in Manassas, Virginia.
