Negril Lighthouse
Negril Lighthouse was built in 1894 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 deep, which is kept filled with water to keep the ( 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.Negril Point Lighthouse , Jamaica National Heritage Trust, 2005. Frans Eijgenraam, 2000.

Westmoreland Parish, Jamaica
Westmoreland is the westernmost parish in Jamaica, located on the south side of the island. It is situated south of Hanover, southwest of Saint James, and northwest of Saint Elizabeth, in the county of Cornwall. The chief town and capital is Savanna-la-Mar. Negril, a famous tourist destination, is also situated in the parish. History The earliest inhabitants of Westmoreland were the Arawak and Ciboney Indians. The Ciboney were first to arrive, from the coast of South America, around 500 BC. Known as "cave dwellers", they lived along the cliffs of Negril. The labyrinth of caves and passageways beneath what is now the Xtabi Hotel in Negril are one of the first known settlements of Ciboney Indians in Jamaica. Christopher Columbus stopped at what became Westmoreland on his second voyage when he landed in Jamaica. One of the first Spanish settlements was also built at present-day Bluefields in this parish. The English took over the island from Spanish rule in 1655. Colonists name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

Directorate Of Overseas Surveys
The Ordnance Survey International or Ordnance Survey Overseas Directorate its predecessors built an archive of air photography, map and survey records for the United Kingdom from 1946 to 1999. The Ordnance Survey International Collection (formerly the Ordnance Survey International Library) held mapping records that were acquired outside the UK. Although the international division opened in 1946, the OS had been involved in overseas work for almost a century (notably the 1864-65 Ordnance Survey of Jerusalem). The agency was closed in 2001. History The agency In 1946 the ''Directorate of Colonial Surveys'' (DCS) was established by the Colonial Office to provide a central survey and mapping organisation for British colonies and protectorates. In 1957, with the imminent decolonisation of many British territories, it was renamed the ''Directorate of Overseas Surveys'' (DOS). Government reviews during the 1970s led to it being merging into the Ordnance Survey (OS) in 1984 whence it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses Completed In 1894
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
