The beauty, mystery and romance of lighthouses that have fascinated and enchanted people for centuries. The four stamp designs stamps celebrate five historic lighthouses: Montauk Point, NY; Navesink, NJ; Erie Harbor, PA; Harbor of Refuge, DE; and Thomas Point Shoal, MD.

A temporary light was established on the south end of the recently completed National Harbor of Refuge Breakwater on January 1, 1902. It was replaced in 1908 by a three-story frame lighthouse. A series of storms damaged the structure, resulting in its removal and replacement in 1926. The present Harbor of Refuge Lighthouse became operational on November 15, 1926. This white and black structure consists of a three-story cylindrical tower with a watch room above. The foundation is a cast iron caisson of curved plates bolted together. It is lined with three feet of concrete. The lighthouse stands seventy-six feet above the breakwater. It shows a flashing white light seventy-two feet above mean high water which is visible fourteen miles to sea. Coast Guard light keepers manned the light until it was automated in December 1973. In 2004, the Harbor of Refuge Lighthouse was transferred by the United States Department of the Interior to the Delaware River and Bay Lighthouse Foundation.
