Poolbeg Lighthouse
Poolbeg Lighthouse is an active aid to navigation at the mouth of the River Liffey, near Poolbeg in Dublin, Ireland. First established in 1767, it initially operated on candlepower but this was changed to oil in 1786. It was re-designed and re-built into its present form in 1820. Location The lighthouse, one of a formation of three, is located on the Great South Wall (South Bull Wall), at the Port of Dublin, which extends from Ringsend's Poolbeg peninsula nearly four miles out into Dublin Bay. The wall was the world's longest at the time of its building, and remains one of the longest sea-walls in Europe. One of the other two lighthouses is located on the Bull Wall opposite, and the other on a wooden platform mid-channel. The Poolbeg Lighthouse is a handsome and conspicuous feature in the bay, in which it occupies an almost central position. It is nearly equidistant from Dublin, Dún Laoghaire, and Howth, and commands extensive views of the shores of the bay, with an unbr ...

Dublin
Dublin (; , or ) is the capital and largest city of Ireland. On a bay at the mouth of the River Liffey, it is in the province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixth largest in Western Europe after the Acts of Union in 1800. Following independence in 1922, Dubli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Completed In 1820
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] |
Towers Completed In 1768
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 langua ...

Lighthouses In Ireland
This is a list of lighthouses in Ireland. The Commissioners of Irish Lights are responsible for the majority of marine navigation aids around the island though a small number are maintained by local harbour authorities. The main list identifies those lighthouses in a clockwise direction starting with Crookhaven, Crookhaven lighthouse, County Cork. Maintained by Commissioners of Irish Lights Maintained by other Irish marine authorities A smaller number of active lighthouses are operated by other authorities, primarily the port and harbour companies located around the Geography of Ireland, Irish coast. Inactive Improvements and changes to the aids to navigation around the Irish coast, has meant that there are a number of lighthouses that have been decommissioned. This list includes those where the tower or structure is still in existence. Some of these have been reused, such as Ferris Point which is now a vessel control tower.

Poolbeg Lighthouse, Great South Wall, Dublin
Poolbeg () is an artificial peninsula extending from Ringsend, Dublin, into Dublin Bay. History The Poolbeg peninsula was built between the mid 18th century and the present day, starting with the Ballast Office Wall, the first section of the Great South Wall to be built on what was then a sand bar known as the South Bull. As the various sections of the Great South Wall were built, further sand bars formed where the river Liffey left its silt, and these were gradually filled with rubble and built upon. The name “Poole Begge” referred originally to a tidal pool located out into Dublin harbour and surrounded by sand bars. This was where the Poolbeg lighthouse was built in 1767. The lighthouse was connected to land by the Great South Wall completed in 1795. Overview The Poolbeg “peninsula” is home to a number of landmarks including the Great South Wall, the Poolbeg Lighthouse, the Irishtown Nature Park, the southern part of Dublin Port, an energy-from-waste facility, an ...

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 crossing, 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 u ...
