Point Arena Lighthouse 154th Anniversary

The Point Arena Lighthouse, was first lit on May 1st, 1870. Its brick-and-mortar tower featured ornate iron balcony supports and a large Keepers’ residence with enough space to house four Light Keeper families. In April of 1906, a devastating earthquake struck the tower. The tower was damaged beyond repair and had to be completely deconstructed

The United States Lighthouse Service contracted with a San Francisco-based company to build a new Lighthouse that could withstand any future earthquakes. The company built factory smokestacks, which accounts for the final design of the current Point Arena Lighthouse. The new design featured steel reinforcement rods encased in concrete, and was the first lighthouse to be built in this manner.

The new Lighthouse began operation on September 15, 1908, nearly 29 months after the quake. It stands 115 feet tall and features a 1st Order Fresnel Lens, seven feet in diameter and weighing 4,700 pounds. The lens is made up of 258 hand-ground glass prisms all focused toward three sets of double bulls eyes. It is these bull’s eyes that gave the Point Arena Lighthouse its unique “light signature” of two flashes every six seconds.

In 1984, a nonprofit organization called the Point Arena Lighthouse Keepers, Inc. acquired the Light Station as part of a 25-year land lease from the Coast Guard and the Department of Transportation. In November of 2000, the nonprofit group became the official owners of the property due to their diligent historic preservation and educational efforts.
