The following in part is from the lighthouse’s website:
_"The first Point Arena Lighthouse was constructed in 1870. Its brick and mortar tower featured ornate iron balcony supports and a large Keeper residence with enough space to house several families. In April of 1906, a devastating earthquake struck the tower. Damage from the trembler occurred all along the San Andreas Fault, which runs very close to Point Arena. In the town itself, many buildings were reduced to rubble, and at the Light Station, the Keeper’s residence and Lighthouse were damaged so severely that they were rendered condemned, and ultimately torn down.
The United States Lighthouse Service contracted with a San Francisco based company to build a new lighthouse here to withstand any future earthquakes. The company built factory smokestacks, which accounts for the final design for the new 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 in 1908, nearly 18 months after the quake. It stands 115 feet tall, and features a 1st Order Fresnel Lens, over six feet in diameter and weighing more than six tons. The lens is made up of 666 hand-ground glass prisms all focused toward three sets of double bulls eyes. It is these bulls eyes that gave the Point Arena Lighthouse its unique “light signature” of two flashes every six seconds. This incredible optic, that holds an appraised value of over $3.5 million, is set in solid brass framework, built in France."_
