Negril Lighthouse was built in 1894 1.5 mi south south east of the westernmost tip of the island of Jamaica by the French company Barber & Bernard. It is one of the earliest concrete lighthouses. Its foundation is a tank 14 ft deep, which is kept filled with water to keep the 20 m (27 m according to Rowlett) reinforced concrete tower balanced and secured in the event of an earthquake. The tower is topped with a lantern and gallery. An automatic white light 30 m (100 feet) above sea level flashes every two seconds. The light was operated by gas initially, switching to acetylene in 1956 and solar energy in 1985. Several adjacent one-story frame keeper's houses are staffed. The site is a well-known attraction of the Negril area. It is maintained by the Port Authority of Jamaica, an agency of the Ministry of Transport and Works.
