Cape Arago's tower is 44 feet high, and was illuminated in 1934. However, there were two other lighthouses built earlier on Cape Arago. The first tower was lit on November 1, 1866, and was Oregon's second lighthouse in operation. This lighthouse was a 25 foot octagonal tower supported by iron stilts. Then, on July 1, 1909, a second lighthouse was completed and began to operate. This house was 25 feet higher and included a siren fog-signal.
