Tillamook Rock Light is a deactivated lighthouse on the Oregon Coast of the United States.
It is located approximately 1.2 miles offshore from Tillamook Head, and 20 miles south
of the Columbia River, 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 began in 1880. The construction took more than 500 days to finish,
with its completion in January 1881. In early January 1881, when the lighthouse was
near completion, the barque Lupatia was wrecked near the rock during inclement weather
and sank, killing all 16 crew members.
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"
(or Tillie). Over the years, storms have damaged the lighthouse, shattered the lens,
and eroded the rock. It was decommissioned in 1957.
