Howth Head
Howth Head ( ; ''Ceann Bhinn Éadair'' in Irish) is a peninsula northeast of the city of Dublin in Ireland, within the governance of Fingal County Council. Entry to the headland is at Sutton while the village of Howth and the harbour are on the north-eastern face. Most of Howth Head is occupied by the Hill of Howth, though there are other regions, such as the tombolo at Sutton, extensive beaches on the northern shores, and small ones in other parts. The Baily Lighthouse is on the southeastern part of Howth Head. Nearby are the districts of Baldoyle and Portmarnock, and adjacent is the nature reserve of North Bull Island. History The earliest mention of the peninsula may be on a map attributed to Claudius Ptolemy, where it was called ''Edri Deserta'' or in Greek (''Edrou Heremos'', Edar's isolated place). Here it was portrayed as an island, but it is not clear if this was due to actual separation from the headland or inaccurate information available to the cartographer. Oth ...

Ireland
Ireland (, ; ; Ulster Scots dialect, Ulster-Scots: ) is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland (officially Names of the Irish state, named Irelanda sovereign state covering five-sixths of the island) and Northern Ireland (part of the United Kingdomcovering the remaining sixth). It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest in the world. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islands by population, ...

Ptolemy
Claudius Ptolemy (; , ; ; – 160s/170s AD) was a Greco-Roman mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine science, Byzantine, Islamic science, Islamic, and Science in the Renaissance, Western European science. The first was his astronomical treatise now known as the ''Almagest'', originally entitled ' (, ', ). The second is the ''Geography (Ptolemy), Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian physics, Aristotelian natural philosophy of his day. This is sometimes known as the ' (, 'On the Effects') but more commonly known as the ' (from the Koine Greek meaning 'four books'; ). The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Fulmar
The northern fulmar (''Fulmarus glacialis''), fulmar, or Arctic fulmar is an abundant seabird found primarily in subarctic regions of the North Atlantic and North Pacific oceans. There has been one confirmed sighting in the Southern Hemisphere, with a single bird seen south of New Zealand. Fulmars come in one of two colour morphs; a light one in temperate populations, with white head and body and grey wings and tail, and a dark one in arctic populations, which is uniformly grey; intermediate birds are common. Svensson, L., Mullarney, K., & Zetterström, D. (2009) '' Collins Bird Guide'', ed. 2. Though similar in appearance to gulls, fulmars are in fact members of the family Procellariidae, which includes petrels and shearwaters. The northern fulmar and its sister species, the southern fulmar (), are the only extant members of the genus . The fulmars are in turn a member of the order Procellariiformes, and they all share certain identifying features. First, they have nasal pa ...

Common Guillemot
The common murre or common guillemot (''Uria aalge'') is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands. Common murres are fast in direct flight but are not very agile. They are highly mobile underwater using their wings to 'fly' through the water column, where they typically dive to depths of . Depths of up to have been recorded. Common murres breed in colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated between the adult's feet on a bare rock ledge on a cliff face. Eggs hatch after ~30 days incubation. The chick is born downy and can regulate its body temperature after 10 days. Some 20 days after hatching, the chick leaves its nesting ledge and heads for the sea, unable to fly, but gliding for some distance with ...

Razorbill
The razorbill (''Alca torda'') is a North Atlantic colonial seabird and the only extant member of the genus ''Alca (bird), Alca'' of the family Alcidae, the auks. It is the closest living relative of the extinct great auk (''Pinguinus impennis''). Historically, it has also been known as "auk", "razor-billed auk" and "lesser auk". Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females. This agile bird, which is capable of both flight and diving, has a predominantly aquatic lifestyle and only comes to land in order to breed. It is Monogamy in animals, monogamous, choosing one partner for life. Females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating, and once the chick has hatched, they take turns foraging for their young. Presently, this species faces major threats, including the dest ...

Killiney Hill
Killiney Hill () is the southernmost of the two hills which form the southern boundary of Dublin Bay, the other being Dalkey Hill. These two hills form part of Killiney Hill Park. Crowned by a monument, Killiney Hill is 153 metres high and has views over the surrounding areas: Dublin to the northwest; the Irish Sea and the mountains of Wales (on a clear day) to the east and southeast; and Bray Head and the Wicklow Mountains to the south. The hill was higher in the past but material was removed from the summit for the construction of the pier at Dún Laoghaire. The obelisk was completed in 1742 and commemorates the victims of the Irish Famine (1740–41), Irish Famine of 1740-41. History Killiney Hill stands in the former townland of Mount Mapas, or Scalpwilliam, first mentioned under that name in the beginning of the 17th century. Former residents included Captain Edward Maunsell, who served as the High Sheriff of County Dublin in 1755, followed by Colonel the Hon. Henry Loftus, ...

Dalkey Hill
Dalkey Hill ( ; ) is the northernmost of the two hills which form the southern boundary of Dublin Bay (the other being Killiney Hill). Dalkey Hill is 140 metres high and has views over the surrounding areas : Dublin to the northwest; the Irish Sea and the mountains of Wales (on a clear day) to the east and southeast; and Bray Head and the Wicklow Mountains to the south. Dalkey Hill and Killiney Hill are both part of Killiney Hill Park, a small public park overlooking the villages of Dalkey to the north and Killiney to the west. The park is crossed by a number of walking tracks, and with views from all directions, is a used by walkers and hikers from the surrounding areas. Extensive quarrying of Dalkey Hill in the 19th century has resulted in the existence of Dalkey Quarry, which is now a rock-climbing location. Dalkey Hill and areas to the east and south of Dalkey Village were formerly the lands of Dalkey Common. References {{Mountains and hills of Leinster Hill ...

Dublin Bay
Dublin Bay () is a C-shaped inlet of the Irish Sea on the east coast of Ireland. The bay is about 10 kilometres wide along its north–south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. Bull Island, North Bull Island is situated in the northwest part of the bay, where one of two major inshore sand banks lay, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams. The metropolitan area of the city of Dublin surrounds three sides of the bay (the north, west, and south), while the Irish Sea lies to the east. Dublin was founded by the Vikings at the point where they were able to ford the River Liffey with the first wattle b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tombolo
A tombolo is a sandy or shingle isthmus. It is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island. The word ''tombolo'' is from the Italian ', meaning 'pillow' or 'cushion', and sometimes translated incorrectly as '' ayre'' (an ayre is a shingle beach of any kind). Several islands tied together by bars which rise above the water level are called a tombolo cluster. Two or more tombolos may form an enclosure (called a lagoon) that can eventually fill with sediment. Formation The shoreline moves toward the island (or detached breakwater) owing to the accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs. Wave diffraction and refraction True tombolos are formed by wave refraction and diffraction. As waves near an island, they are slowed by the shallow water surroundi ...

Dolmen
A dolmen, () or portal tomb, is a type of single-chamber Megalith#Tombs, megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the Late Neolithic period (40003000 BCE) and were sometimes covered with earth or smaller stones to form a tumulus (burial mound). Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance. In many instances, the covering has eroded away, leaving only the stone "skeleton". In Sumba (Indonesia), dolmens are still commonly built (about 100 dolmens each year) for collective graves according to lineage. The traditional village of Wainyapu, Sumba, Wainyapu has some 1,400 dolmens. Etymology Celtic or French The word ''dolmen'' entered archaeology when Théophile Corret de la Tour d'Auvergne used it to describe megalithic tombs in his (1796) using the spelling ''dolmin'' (the current spelling was introduced about a decade later and h ...
