Tillamook Rock Lighthouse is a decommissioned lighthouse off the coast of Oregon. The Light was officially lit on January 21, 1881. At the time, it was the most expensive West Coast lighthouse ever built. Due to the erratic weather conditions, and the dangerous commute for both keepers and suppliers, the lighthouse was nicknamed “Terrible Tilly”. Over the years, storms have damaged the lighthouse, shattered the lens, and has eroded the rock. It was decommissioned in 1957, and has since been sold to a private party.
