The Cape Henlopen Beacon — the light nobody remembers

Why one lighthouse was not enough

A lighthouse tells a mariner two different things, and they are hard to do with one light. A tall coastal tower set back from the water announces a landfall — it says this is Cape Henlopen, you have arrived — and it needs height and distance to be seen far out. A beacon at the point marks the immediate hazard: the shoal, the tip, the exact edge of the sand you must not run onto.

Cape Henlopen needed both, because the cape is not a fixed object. It is a spit of sand that grows and shifts; its point migrates. The great light of 1767–69 stood back behind the dune, and a supplementary light was placed nearer the water where the danger actually was.

The first of these smaller lights went into service in 1824, and a light of this kind guarded the tip until 1885 — the year the Delaware Breakwater East End Light took up its duty offshore, which is unlikely to be a coincidence. As the breakwaters and their lights reorganised the approach, the beacon on the point became redundant.

Living with a moving cape

The recurring theme in every Cape Henlopen light is impermanence. The main tower was abandoned in 1924 after storm damage in 1920 and went over the edge in 1926. The beacons were smaller, closer to the water, and correspondingly more vulnerable — a light at the tip of a sand spit is built on the least stable ground on the coast.

That is why there were two beacons in succession rather than one long-lived structure. The cape kept moving out from under whatever was placed on it, and the Lighthouse Establishment kept rebuilding, until the arrival of offshore lights on stone breakwaters solved the problem by putting the light on something that would stay put.

What is there now

Nothing of the beacons survives above ground, and the ground itself has moved. The tip of Cape Henlopen today is not where it was in 1824, and the visitor looking for the site is looking at water, sand, or a different piece of sand.

What remains is inside Cape Henlopen State Park, where the twentieth-century concrete of Fort Miles is undergoing the same slow argument with the shoreline that the beacons lost. The cape has never stopped doing this.

“Many people familiar with the old Cape Henlopen Lighthouse that fell into the Atlantic Ocean in April of 1926 are lacking in knowledge about a supplementary light deemed necessary…”
