Marcus Hook Range Rear Light

The Marcus Hook Range Rear Light is a concrete navigation tower in New Castle County standing 32 meters tall and equipped with a fixed red light. The structure continues to guide vessel traffic on the Delaware River as an active beacon.

Construction started in 1915 with a temporary structure, followed by completion of the reinforced concrete tower in 1918. The new tower was built to support the growing river traffic on the Delaware.

The tower reflects the river's role as a major shipping route, a waterway that has shaped trade and commerce in the region for centuries. The red light visible from a distance marks this connection to maritime life in the area.

The tower operates continuously throughout the day and night, continuously emitting its red light to guide vessels. Visitors should view the structure from the water or at a safe distance from the riverbank.

The beacon holds the highest focal height of any lighthouse on the Atlantic coast of the United States when measured above mean high water. This distinction makes it a remarkable reference point for maritime navigation.
