Negril Lighthouse was built in 1894 1.5 miles (2.4 km) south south east of the westernmost tip of the island by the French company Bubbler & Bernard.[3] It is one of the earliest concrete lighthouses.[1]
Its foundation is a tank 14 feet (4.3 m) deep, which is kept filled with water to keep the 20-metre (66 ft)[3] (27 metres (89 ft) according to Rowlett)[1] reinforced concrete tower balanced and secured in the event of an earthquake.[3] The tower is topped with a lantern and gallery.[1]
An automatic white light 30 m (100 feet) above sea level flashes every two seconds.[1] The light was operated by gas initially, switching to acetylene in 1956 and solar energy in 1985.[3][4]
Several adjacent one-story frame keeper's houses are staffed.[1]
The site is a well-known attraction of the Negril area.[1]
It is maintained by the Port Authority of Jamaica, an agency of the Ministry of Transport and Works.[1]
