Point Arena Light

Point Arena Light is a maritime lighthouse in Mendocino County on the Northern California Pacific coast, built from reinforced concrete and reaching a height of 35 meters (115 feet). The tower stands on rocky cliffs above the open ocean and houses a lens that makes the light visible over long distances.

The site was established in 1870 to protect merchant vessels from dangerous waters along this coast, where strong currents meet rocky headlands. An earthquake destroyed the original brick tower in 1906, prompting engineers to design the current concrete structure as its replacement.

Lighthouse keepers who lived here from 1870 maintained foghorns by hand and polished lenses daily with special cloths. Visitors can see original furniture and handwritten logbooks in restored keeper houses that still preserve their 19th-century floor plans.

Guided walks take visitors up a spiral staircase to the observation platform, where the ocean and coastline spread out in all directions. The climb requires moderate fitness and good weather, as wind gusts can be strong at the top.

The original 1908 Fresnel lens still rotates mechanically through a weight system that must be wound by hand every few hours. This technique allows the tower to rotate its beam without electricity, just as generations of keepers did before.
