About Schuylkill River Entrance Range Rear Lighthouse
This steel skeletal tower stands 18 meters tall on the east side of the Schuylkill River, approximately 600 meters from its mouth. Established in 1875, the rear range light helps guide vessels by aligning with a front light, defining the safe channel. Its green light flashes once every 4 seconds, becoming visible only when a vessel is on the correct bearing. The structure has a focal height of 19.5 meters and a geographic range of 13 nautical miles. It is situated near the Philadelphia Navy Yard.
Why it matters: This range light is indispensable for safe navigation into the Schuylkill River, particularly for vessels accessing port facilities upstream. Its precise green light, visible only on the range line, prevents groundings and collisions in a busy river entrance.
