Holyhead Mountain
Holyhead Mountain (''Mynydd Twr'' in Welsh: from ''(pen)twr'', meaning "tower") is the highest mountain on Holy Island, Anglesey, and the highest in the county of Anglesey, north Wales. It lies about two miles west of the town of Holyhead, and slopes steeply down to the Irish Sea on two sides. Ireland can be seen from here on a clear day and the mountain is an important site for seabirds. The mountain Holyhead Mountain is located on Holy Island, Anglesey, jutting out into the Irish Sea. At , it is the highest mountain in the county of Anglesey, being higher than Bodafon Mountain () on the main island. On the east side of the mountain is the site of a late Roman watchtower called '' Caer y Tŵr'' (Tower Fortress), from which Holyhead Mountain's Welsh name is derived. Holyhead Mountain also has the remains of a group of Iron Age huts near its foot. This shows evidence of being occupied in the middle part of the Stone Age, the Neolithic Age, the Bronze Age and the Iron Age. There ...

Holy Island, Anglesey
Holy Island ( cy, Ynys Gybi, 'the island of (Saint) Cybi') is an island () on the western side of the larger Isle of Anglesey, Wales, from which it is separated by the Cymyran Strait. It is called "Holy" because of the high concentration of standing stones, burial chambers, and other religious sites on the small island. The alternative English name of the island is Holyhead Island. According to the 2011 UK Census, the population was 13,659, of which 11,431 (84%) lived in the largest town, Holyhead. History Irish pirates invaded Anglesey following the end of Roman rule in Britannia. Cunedda first began warfare against the Irish but ultimately Cadwallon Lawhir defeated the Irish on Holy Island. Natural features There are a variety of natural habitats on the island including mudflats, dunes, marshes, and beaches. Practically nothing is left of the oak forest that covered almost all of the island before the arrival of Neolithic farmers. The western side of the island is t ...

Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangulation Station
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The nomenclature varies regionally: they are generally known as trigonometrical stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa. Use The station is usually set up by a government with known coordinates and elevation published. Many stations are located on hilltops for the purposes of visibility. A graven metal plate on the top of a pillar may provide a mounting point for a theodolite or reflector, often using some form of kinematic coupling to ensure reproducible positioning. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and other ...

Grey Seal
The grey seal (''Halichoerus grypus'') is found on both shores of the North Atlantic Ocean. In Latin Halichoerus grypus means "hook-nosed sea pig". It is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". It is the only species classified in the genus ''Halichoerus''. Its name is spelled gray seal in the US; it is also known as Atlantic seal and the horsehead seal. Taxonomy There are two recognized subspecies of this seal: The type specimen of ''H. g. grypus'' (Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught off the island of Amager, Danish part of the Baltic Sea) was believed lost for many years but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it was first described in Otto Fabricius' book on the animals in Greenland: ''Fauna Groenlandica''). The name ''H. g. grypus'' was therefore transferred to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or palaearctic oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher (''Haematopus meadewaldoi''), formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher. This oystercatcher is the national bird of the Faroe Islands. Taxonomy The Eurasian oystercatcher was listed by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἳμα meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Stonechat
The European stonechat (''Saxicola rubicola'') is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae. Taxonomy and systematics The European stonechat was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Motacilla rubicola''. This species is now placed in the genus ''Saxicola'' that was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The English name derives from its call, sounding like two stones knocked together. The scientific name ''Saxicola'' means "rock-dweller", from Latin ''saxum'' meaning "a rock" and ''incola'' meaning "dwelling in". The specific epithet combines the Latin ''rubus'' meaning "brambles" with ''incola''. The subspecies name ''hibernans'' refers to ...

Atlantic Puffin
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin is found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on small fish and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, bold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. 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 on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

Wicklow Mountains
The Wicklow Mountains (, archaic: ''Cualu'') form the largest continuous upland area in the Republic of Ireland. They occupy the whole centre of County Wicklow and stretch outside its borders into the counties of Dublin, Wexford and Carlow. Where the mountains extend into County Dublin, they are known locally as the Dublin Mountains (''Sléibhte Bhaile Átha Cliath''). The highest peak is Lugnaquilla at . The mountains are primarily composed of granite surrounded by an envelope of mica-schist and much older rocks such as quartzite. They were pushed up during the Caledonian orogeny at the start of the Devonian period and form part of the Leinster Chain, the largest continuous area of granite in Ireland and Britain. The mountains owe much of their present topography to the effects of the last ice age, which deepened the valleys and created corrie and ribbon lakes. Copper and lead have been the main metals mined in the mountains and a brief gold rush occurred in the 18th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Stack
South Stack ( cy, Ynys Lawd) is an island situated just off Holy Island on the northwest coast of Anglesey, Wales. Geology South Stack is an island known as a sea stack. It was formed by the wave erosion of sedimentary rocks that once connected the island to the mainland. The area is known geologically as the South Stack Formation. Its strata includes sandstones and interbedded shales which have been contorted by large folds and crumples. The folds can be seen in the seacliffs (best viewed from the steps leading down to the lighthouse). Thick beds of pure Holyhead Quartzite, which forms the bulk of Holyhead Mountain, lie above these folded sedimentary rocks. Recent studies suggests the rocks appearance was caused by large scale earth movements which is not a part of the normal sedimentary process; however, this theory remains controversial. Similar evidence of upthrusts can be seen in the cliffs to the south of South Stack. The fascinating geology of South Stack has been ...

Brickwork
Brickwork is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks called '' courses'' are laid on top of one another to build up a structure such as a brick wall. Bricks may be differentiated from blocks by size. For example, in the UK a brick is defined as a unit having dimensions less than and a block is defined as a unit having one or more dimensions greater than the largest possible brick. Brick is a popular medium for constructing buildings, and examples of brickwork are found through history as far back as the Bronze Age. The fired-brick faces of the ziggurat of ancient Dur-Kurigalzu in Iraq date from around 1400 BC, and the brick buildings of ancient Mohenjo-daro in Pakistan were built around 2600 BC. Much older examples of brickwork made with dried (but not fired) bricks may be found in such ancient locations as Jericho in Palestine, Çatal Höyük in Anatolia, and Mehrgarh in Pakistan. These structures have survived from the Stone Ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Holyhead
300px, Just inside the 'New' harbour at Holyhead port., alt=Port of Holyhead From geograph.org.uk 8 October 2007 The Port of Holyhead ( cy, Porthladd Caergybi) is a commercial and ferry port in Anglesey, Wales, handling more than 2 million passengers each year. It covers an area of 240 hectares, and is operated by Stena Line Ports Ltd. The port is the principal link for crossings from north Wales and central and northern England to Ireland. The port is partly on Holy Island and partly on Salt Island ( cy, Ynys Halen). It is made up of the Inner Harbour, the Outer Harbour and the New Harbour (opened in 1880), all sheltered by the Holyhead Breakwater which, at 2.7 kilometres, is the longest in the UK. History Formerly subservient to Beaumaris as the region's main port, Holyhead came into its own in the early 19th century, when Thomas Telford built a new road to connect north Wales with London. The Admiralty Pier was constructed in 1821, and was used by the City of Dublin Steam P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
