Tillamook Rock Lighthouse

Tillamook Rock Light is a deactivated lighthouse on the northern Oregon Coast of the United States. It is located approximately 1.2 miles offshore from Tillamook Head, and 20 miles south of the mouth of the Columbia River near Astoria, situated on less than an acre of basalt rock in the Pacific Ocean. The construction of the lighthouse was commissioned in 1878 by the United States Congress and took more than 500 days to complete. Shortly before the completion of the lighthouse in January 1881, the barque Lupatia was wrecked near the rock during foggy weather and sank, with the loss of all 16 crew members.

Tillamook Rock Light was officially lit on January 21, 1881. At the time, it was the most expensive lighthouse to be built on the West Coast. Due to the local erratic weather conditions, and the dangerous commute for both keepers and suppliers, the lighthouse earned the nicknamed "Terrible Tilly".
