USS Philadelphia is a gunboat (referred to in contemporary documents as a gundalow or gondola) of the Continental Navy. She was constructed from July-August 1776 for service during the American Revolutionary War. Manned by Continental Army soldiers, she was part of a fleet under the command of General Benedict Arnold that fought against the British Royal Navy in the Battle of Valcour Island on Lake Champlain. Philadelphia was sunk during the battle on 11 October 1776. In 1935, amateur military marine archaeologist Lorenzo Hagglund located her remains standing upright at the bottom of Lake Champlain. The wreck was raised to the surface and salvaged. In 1961 she was bequeathed to the Smithsonian Institution. Philadelphia and associated artifacts are now part of the permanent collection of the National Museum of American History, in Washington, D.C., where curator Philip K. Lundeberg was responsible for arranging her initial display. The vessel is listed on the National Register of Historic Places and is a National Historic Landmark.

Since 1964 it has been in the National Museum of American History. Horatio Greenough based Enthroned Washington on Phidias' great statue of Zeus Olympios, one of the Seven Wonders of the Ancient World and destroyed in Late Antiquity.

14th Street NW/SW is a street in Northwest and Southwest quadrants of Washington, D.C., located 1.25 miles (2.01 km) west of the U.S. Capitol. It runs from the 14th Street Bridge north to Eastern Avenue. Northbound U.S. Route 1 runs along 14th Street from the bridge to Constitution Avenue, where it turns east with US 50. US 1 southbound previously used 15th Street NW due to the ban on left turns from westbound Constitution Avenue to 14th Street, but it now uses the Ninth Street Tunnel, five blocks to the east. 14th Street crosses the National Mall and runs near the White House and through the western side of Washington's Logan Circle neighborhood. Because it connects to one of the main bridges crossing the Potomac River into Virginia, 14th Street has always been a major transportation corridor. It was the location of one of the first streetcar lines, and today it is the location of several afternoon carpooling "slug lines", which allow commuters to meet the high-occupancy vehicle requirements of I-395, the Henry G. Shirley Memorial Highway.
