Inistrahull Lighthouse
Inishtrahull Lighthouse is the northerly most lighthouse in Ireland located on the Inishtrahull Island off the coast of County Donegal. Coupled with the lighthouse on Tory Island they form the two main landfall lights for shipping from the Atlantic rounding the north coast of Ireland, and navigation to local shipping. Work on the first lighthouse, situated at the east end of the island began in 1812, primarily due to Royal Navy ships using Lough Foyle. Designs for the lighthouse were drawn up by a George Halpin, a Senior Inspector of Lighthouses. Acting on behalf of the Corporation for Preserving and Improving the Port of Dublin. The first Light was established on 17 March 1813. The height of the tower was approx. 12.8 metres. Later a dioptric apparatus was installed in the tower and came into operation on 29 September 1864. At the start of the 20th century, it was decided that a fog signal was required in the area of Malin Head. It was decided that it would be constructed at ...

Lighthouse Inishtrahulllighthousesmall
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), 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 signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commissioners Of Irish Lights
The Commissioners of Irish Lights ( ga, Coimisinéirí Soilse na hÉireann), often shortened to Irish Lights or CIL, is the body that serves as the general lighthouse authority for Northern Ireland and the Republic of Ireland and their adjacent seas and islands. As the lighthouse authority for the island of Ireland it oversees the coastal lights and navigation marks provided by the local lighthouse authorities, the county councils and port authorities. It is funded by light dues paid by ships calling at ports in the Republic of Ireland, pooled with dues raised similarly in the United Kingdom. This recognizes that a large volume of shipping, typically transatlantic, relies on the lights provided by Irish Lights. History Signal fires to guide shipping have long existed. Hook Head has the oldest nearly continuous light in Ireland, originally a signal fire or beacon tended by the monk Dubhán in the fifth century. Monks continued to maintain the light until the Cromwellian co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In County Donegal
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Towers Completed In 1813
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

International Association Of Lighthouse Authorities
The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA), previously known as International Association of Lighthouse Authorities, is an intergovernmental organization founded in 1957 to collect and provide nautical expertise and advice. IALA is also known by its French name of ''Association Internationale de Signalisation Maritime'' (AISM). Background IALA brings together representatives of the aids to navigation services of about 80 countries for technical coordination, information sharing, and coordination of improvements to aids to navigation throughout the world. It was established in 1957 to provide a permanent organization to support the goals of the Technical Lighthouse Conferences, which had been convening since 1929. The General Assembly of IALA meets about every four years. The council of 24 members meets twice a year to oversee the ongoing programs. Four committees maintain work programs established for four year periods: * ENAV&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malin Head
Malin Head ( ga, Cionn Mhálanna) is the most northerly point of mainland Ireland, located in the townland of Ardmalin on the Inishowen peninsula in County Donegal. The head's northernmost point is called Dunalderagh at latitude 55.38ºN. It is about 16 km (10 mi) north of the village of Malin. The island of Inishtrahull is further north, about 10 km (6 mi) northeast of the headland. Malin Head gives its name to the Malin sea area. There is a weather station on the head, which is one of 22 such stations whose reports are broadcast as part of the BBC Shipping Forecast. A tower built in 1805 is on Altnadarrow, also known locally as the Tower Hill. Ptolemy's ''Geography'' (2nd century AD) described a point called Βορειον (''Boreion'', "the northern") which probably referred to Malin Head. Locality To the northeast Inistrahull Island can be seen. The first lighthouse on the island was put into operation in 1813, and the light flashes every 30 seco ...
