In 1855, Congress appropriated $15,000 for the construction of a lighthouse on an islet near Crescent City. Connected to Battery Point by an isthmus visible and crossed on foot, at low tide, it became one of the first lighthouses on the California coast. They lit the fourth-order Fresnel lens in 1856. When automated in 1953, a modern 375mm lens replaced the Fresnel lens. In 1964 the Alaska earthquake hit with a magnitude of 9.2. It caused a tsunami that created damage far into Crescent City but the lighthouse survived. In the following year, a beacon replaced the Fresnel lens in the tower. A flashing light at the end of the breakwater served as the harbor's navigational aid. In 1982, they turned on light in the lighthouse tower and the Battery Point Lighthouse became listed as a private aid to navigation.
