The First Troop Philadelphia City Cavalry, also known as the First City Troop, is a unit of the Pennsylvania Army National Guard. It is one of the oldest military units in the United States still in active service and is among the most decorated units in the U.S. Army. Accordingly, the Troop operates under a number of principles of self-governance unique in the U.S. military, including the election of unit members and officers, voluntarily forgoing pay for military service to the country, continuing to practice horse cavalry skills and tactics, and recruiting a high percentage of its members from veterans of prior active duty service across all branches (many of whom resign past officer commissions to join), as well as older civilian mid-career professionals. It is the only U.S. military unit that owns its own armory building, built with private funds in Philadelphia's Rittenhouse Square neighborhood. As of November 2017, the troop had 46 active members (33 drilling with the A-1/104th CAV), up from 35 in 2014.

It serves as eastbound Pennsylvania Route 3 between 63rd and 33rd Streets. Stratton's Tavern was located on Chestnut Street near Sixth Street. When the citizens of Philadelphia were afraid that the British might attack the essentially unmanned Fort Mifflin, the secretary of the Young Men's Democratic Society called a meeting, to be held at Stratton's Tavern on March 20, 1813.

22nd Street station is an underground trolley station in Center City Philadelphia that serves the SEPTA Subway–Surface Trolley Lines. Similar to 19th Street station, three blocks east of it, the station has two side platforms and a total of four tracks. The station serves only subway–surface trolleys on the two outer tracks; the Market-Frankford Line subway uses the two inner tracks and bypasses the station as it travels between 15th Street and 30th Street station. The station was constructed by the Philadelphia Transportation Company in 1955, a replacement for the nearby 24th Street station just north of Market Street at the east end of the now-removed shared train and trolley bridge over the Schuylkill River. The former station site is now the Crown Lights Building (a tall rectangular black skyscraper topped with 4 large LED message boards atop its upper sides), the headquarters of PECO Energy.
