1. A Bright Beacon Marker
Pigeon Point Lighthouse's tall, double-walled tower supports a huge four-ton lens. The first-order, or largest, Fresnel lens has 1,008 glass elements mounted in a brass framework. This lens system was perfected by Augustin Fresnel, pronounced fra-NELL, in 1822.
Manufactured in France, the lens focuses light from a flame or bulb into 24 separate beams that radiate outward, up to 24 miles on a clear night. As the powerful clockwork mechanism slowly rotates the lens, mariners see a white flash every 10 seconds.
"Steadfast, serene, immovable, the same,
Year after year, through all the silent night
Burns on forevermore, that quenchless flame,
Shines on that inextinguishable light!"
From The Lighthouse, a poem by Henry Wadsworth Longfellow

The 24 bulls-eye lenses and 984 prisms create 24 beams of light.
The spiral staircase includes 136 steps forged in San Francisco.
The keepers, or "wickies," maintained the flame and wound the clockwork mechanism of the lens.

When a new tower was built at Cape Hatteras in 1870, the lens was removed and stored briefly at the Staten Island, New York Lighthouse Depot before being shipped in 72 crates around Cape Horn to Pigeon Point.
Weathering storms, witnessing disastrous shipwrecks, and even surviving the earthquakes of 1906 and 1989, this beacon has aided many a ship to safe harbor.

This lens first served in the original Cape Hatteras Lighthouse from 1863-1870.
The 1,008 prisms and lenses light the way for mariners.

5. It Came Down How?

From the top of the tower, 115 feet in the air, the lens was dismantled into 48 panels of glass. One at a time, the panels were removed, wrapped, placed into a cradle and gently lowered to the ground by cable.
The 10 foot-tall beacon was reassembled inside the Fog Signal Building. Looking like pieces of a jigsaw puzzle scattered on the floor, each panel was inspected and cleaned. Then, matching the numbered sections, one to the other, the pieces were fitted back together.
While the tower is being restored, the lens will be on display here in the Fog Signal Building.
