The Currituck Beach Light is a lighthouse in Corolla, North Carolina, on the Outer Banks.
[edit] History
On December 1, 1875 the Currituck Beach Light was completed, located between Cape Henry Light and Bodie Island. Unlike its fellows, Currituck Beach Light wasn't painted, leaving its brick facade visible. In 1939, the lighthouse was automated following a merger of the United States Coast Guard with the Bureau of Lighthouses. [1]
The Outer Banks Conservationists (OBC) performed much of the reconstruction and refurbishing work since 1980 through private funding and volunteer work. Since 1991 visitors have been allowed to climb the original 214 steps to the outdoor gallery. Access to the lens room is not permitted as the first order lens is not only the original lens, but it is still a functioning one. The light comes on every night and shines from 158 feet at 20-second intervals to warn ships hugging the chain of barrier islands along the coast.
In 2003 the Federal Government granted OBC title to the lighthouse itself. The Coast Guard approved OBC’s ownership proposal over that of an application submitted by Currituck County (the county in which the lighthouse is located). Through state and federal legislative maneuvering, the county sued OBC in order to acquire the property. The case was finally settled in 2006. OBC remains the owner of the Currituck Beach Lighthouse.

As it had reported in previous years, the U.S. Light-House Board in 1872 stated that ships, cargoes, and lives continued to be lost along the 40 miles of dark coastline that lay beyond the reaches of existing lighthouses. Southbound ships sailing closer to shore to avoid the Gulf Stream were especially in danger. In response, construction began on the Currituck Beach Lighthouse in 1873 with completion two years later.
The Currituck Beach Lighthouse is a first order lighthouse, meaning it has the largest of seven Fresnel lens sizes. The original source of light was a U.S. mineral oil lamp consisting of five concentric wicks; the largest was 4 inches in diameter.
Before the advent of electricity, a mechanical means was required to rotate the huge lenses that made the light appear to flash. A system of weights suspended from a line powered a clockwork mechanism beneath the lantern--much like the workings of a grandfather clock. The keeper cranked the weights up by hand every two and a half hours.
Like the other lighthouses on North Carolina's Outer Banks, this one still serves as an aid to navigation. The beacon comes on automatically every evening at dusk and ceases at dawn.
With a 20-second flash cycle (on for 3 seconds, off for 17 seconds), the light can be seen for 18 nautical miles. The distinctive sequence enables the lighthouse not only to warn mariners but also to help identify their locations.
The Currituck Beach Lighthouse was the last major brick lighthouse built on the Outer Banks.
Sand Island Light in Alabama was built in 1873 using the same plans as Currituck Beach Light, but with a second order Fresnel lens.
