Forever Young

The first Point Arena Lighthouse was constructed in 1870.

 

In 1906 it was damaged in an earthquake.

 

It was reconstructed and resumed operation in 1908 and featured 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 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
