Lighthouse
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anguilla
Anguilla ( ) is a British Overseas Territory in the Caribbean. It is one of the most northerly of the Leeward Islands in the Lesser Antilles, lying east of Puerto Rico and the Virgin Islands and directly north of Saint Martin. The territory consists of the main island of Anguilla, approximately long by wide at its widest point, together with a number of much smaller islands and cays with no permanent population. The territory's capital is The Valley. The total land area of the territory is , with a population of approximately (). Etymology The native Arawak name for the island was ''Malliouhana''.

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

Sombrero Lighthouse
Sombrero Lighthouse is a lighthouse that marks the Anegada Passage, which is the route from Europe into the Caribbean. The lighthouse is located near the centre of Sombrero island, and reaches a height of almost above sea level. History The first lighthouse, built by the American company that extracted the phosphate on the island, came into operation 1 January 1868. It consisted of a circular pyramidal skeletal tower, on concrete base, with balcony and lantern; by 1893 it was managed by the British Board of Trade. In 1931, the old light system was changed and improved to 200,000 candle power and the tower received its first major repair when the basement was encased in concrete. In 1960 Hurricane Donna damaged the lighthouse; a new one replaced it 20 July 1962. The second light was a square pyramidal skeletal tower high with central cylinder mounted on a concrete base. The lighthouses were staffed from 1868 to 2001. In 2001 Trinity House donated and installed the current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sombrero Light1
A sombrero (Spanish , ) is a type of wide-brimmed Mexican men's hat used to shield the face and eyes from the sun. It usually has a high pointed crown, an extra-wide brim (broad enough to cast a shadow over the head, neck and shoulders of the wearer) that is slightly upturned at the edge, and a chin strap to hold it in place. In Mexico, this hat type is known as a (" charro hat", referring to the traditional Mexican horsemen). In Spanish, any wide-brimmed hat may be considered a sombrero. Design Sombreros, like cowboy hats, were designed in response to the demands of the physical environment. The concept of a broad-brimmed hat worn by a rider on horseback can be seen as far back as the Mongolian horsemen of the 13th century. In hot, sunny climates hats often have evolved wide brims. The exact origin of the Mexican sombrero is unknown, but it is usually accepted that the hat originated with Mestizo cowboys in Central Mexico. Although ''sombrero'' is usually taken to refe ...

Sombrero, Anguilla
Sombrero, also known as Hat Island, is part of the British Overseas Territory of Anguilla and is the northernmost island of the Lesser Antilles. It lies north-west of Anguilla across the Dog and Prickly Pear Passage. The distance to Dog Island, the next nearest island of Anguilla, is . Sombrero is long north–south, and wide. The land area is . Originally, when viewed from the sea, the island had the shape of a sombrero hat, but guano-mining operations have left the island with precipitous sides and a relatively flat top that is above sea level. The surface of the island is rough, and vegetation is sparse. The guano-mining operation yielded some 3000 tons of phosphate a year by 1870. By 1890, the phosphate reserves had been exhausted. History As a result of the Treaty of Utrecht in 1714, Sombrero passed into the hands of the British. Captain Warwick Lake of ''Recruit'' marooned an impressed seaman, Robert Jeffrey, there on 13 December 1807. As it turned out, Jeffrey ...
