Tillamook Rock Light (known locally as Terrible Tilly or just Tilly) is a deactivated lighthouse on the northern Oregon Coast of the United States. 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" (or "Tillie").
