| 説明 | The Currituck Beach Light is a lighthouse located on the Outer Banks in Corolla, North Carolina. An example of Gothic Revival architecture, the Currituck Beach Light was added to the National Register of Historic Places on October 15, 1973.On December 1, 1875, the Currituck Beach Light was completed, located between Cape Henry Light and Bodie Island. Unlike its fellows, Currituck Beach Light was not 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.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 (48 m) at 20-second intervals to warn ships hugging the chain of barrier islands along the coast.The U.S. Light-House Board in 1872 stated that ships, cargoes, and lives continued to be lost along the 40 miles (64 km) 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 date at the top of the entrance to the lighthouse says "1873" because on every lighthouse, the date on the structure is the date that construction began.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 Funck's hydraulic float lamp, fueled with lard oil, and consisting of four concentric wicks. In approximately 1884, the lighthouse converted to a mineral oil (kerosene) lamp with five concentric wicks; the largest was 4 inches in diameter. By 1913, an incandescent oil vapor lamp was used, with kerosene vaporized and forced into the burner by use of a hand pump attached to the storage tank.The Currituck Beach Lighthouse was the last major brick lighthouse built on the Outer Banks.en.wikipedia.org/wiki/Currituck_Beach_Lighten.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
