History Of Dublin To 795
Dublin is Ireland's oldest known settlement. It is also the largest and most populous urban centre in the country, a position it has held continuously since first rising to prominence in the 10th century (with the exception of a brief period in the late 19th and early 20th centuries when it was temporarily eclipsed by Belfast). The historic town grew up on the southern bank of the River Liffey, a few kilometres upstream from the river's outfall into Dublin Bay. The original settlement was situated on a ridge overlooking a shallow ford in the river, which had probably been a regular crossing-point since earliest times. The bedrock underlying the city is calp limestone, a dark shaly sedimentary rock which was once quarried locally and whose mottled grey appearance can still be seen today in some of the city's oldest buildings. Overlying this is a layer of much looser boulder clay of varying thickness. It is no accident that Dublin became the principal city in Ireland. It is ...

Drimnagh
Drimnagh () is a suburb in Dublin, Ireland to the south of the city between Walkinstown, Crumlin and Inchicore, bordered by the Grand Canal to the north and east. Drimnagh is in postal district Dublin 12. History Early to mediaeval Drimnagh derives its name from the word ''druimneach'', or country with ridges. A neolithic settlement discovered and a funerary bowl found in a burial site. The site was demolished, but the bowl is on view in the National Museum. The lands of Drimnagh were taken from their Irish owners by Strongbow, who gave them to the Barnwell family, who had arrived in Ireland with Strongbow in 1167 and had settled in Berehaven in Munster. The people of Munster killed the family except for Hugh de Barnwell, and this youth was given Drimnagh as compensation. The lands and castle were considered safe, as they were relatively far away from the Irish strongholds in the Wicklow mountains. Modern history Drimnagh was farmland until the mid-1930s, when some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambay Island
Lambay Island ( ga, Reachrainn), often simply Lambay, is an island in the Irish Sea off the coast of north County Dublin, Ireland. The largest island off the east coast of Ireland, it is offshore from the headland at Portrane, and is the easternmost point of the province of Leinster. Of volcanic origin, it has been inhabited since the prehistoric period and has been the subject of multiple archaeological studies. Lambay has notable populations of seabirds, a range of local fauna, some not found elsewhere in Ireland, and a colony of wallabies, as well as more than 300 plant varieties, and was the subject of major studies of flora and bird, and a major multidisciplinary study of flora and fauna between 1905 and 1907. The island is privately owned by a trust for members of certain branches of the Baring family and managed by the current Baron Revelstoke. It has a very small permanent population and few buildings but hosts some day visitors and short-stay guests, and there is a ...

Porphyry (geology)
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective ''porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief characteris ...

County Antrim
County Antrim (named after the town of Antrim, ) is one of six counties of Northern Ireland and one of the thirty-two counties of Ireland. Adjoined to the north-east shore of Lough Neagh, the county covers an area of and has a population of about 618,000. County Antrim has a population density of 203 people per square kilometre or 526 people per square mile. It is also one of the thirty-two traditional counties of Ireland, as well as part of the historic province of Ulster. The Glens of Antrim offer isolated rugged landscapes, the Giant's Causeway is a unique landscape and a UNESCO World Heritage Site, Bushmills produces whiskey, and Portrush is a popular seaside resort and night-life area. The majority of Belfast, the capital city of Northern Ireland, is in County Antrim, with the remainder being in County Down. According to the 2001 census, it is currently one of only two counties of the Island of Ireland in which a majority of the population are from a Protestant back ...

Porcellanite
Porcellanite or ''porcelanite'', is a hard, dense Rock (geology), rock somewhat similar in appearance to unglazed porcelain. It is often an impure variety of chert containing clay and calcareous matter. Porcellanite has been found, for example, in Northern Ireland, Poland and the Czech Republic. Tievebulliagh At Tievebulliagh, Northern Ireland, porcellanite is a tough contact metamorphism, contact metamorphosed hornfels formed from a lateritic soil horizon within a basaltic intrusive/extrusive sequence. The rock is black to dark grey in colour. Tievebulliagh is the site of a Neolithic axe or stone tool quarry, and there is another quarry on Rathlin Island. It is likely that roughouts or roughly-shaped prehistoric tools (Celt (tool), celts) were chipped on site before transportation both within Ireland and over the Irish Sea to Britain. It is also likely that the final polish would have been performed near the site of use in cutting vegetation and trees. It was commonly polished ...

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] |
Wedge-shaped Gallery Grave
A gallery grave is a form of megalithic tomb built primarily during the Neolithic Age in Europe in which the main gallery of the tomb is entered without first passing through an antechamber or hallway. There are at least four major types of gallery grave (complex, transepted, segmented, and wedge-shaped), and they may be covered with an earthen mound (or "tumulus") or rock mound (or " cairn"). About gallery graves Archeologist T. Douglas Price argues that the gallery grave was a form of community burial site. Those placed in a gallery grave were most likely members of the same family or hamlet, and probably were intended to reinforce the sense of community. Gallery graves may be straight, or they may form an ell. In some cases, a burial chamber exists at the end of the gallery. The walls of gallery graves were built of orthostats, slab-like stones set upright in the earth. They were roofed with multiple flat stones, although the burial chamber (if one existed) was usually roofe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portal Dolmen
A dolmen () or portal tomb is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the early Neolithic (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.Murphy (1997), 43 In many instances, the covering has eroded away, leaving only the stone "skeleton". The Korean Peninsula is home to the world's highest concentration of dolmens,UNESCO World Heritage List. "Gochang, Hwasun and Ganghwa Dolmen Sites." https://whc.unesco.org/en/list/977 including "cemeteries" consisting of 30–100 examples located in close proximity to each other; with over 35,000 dolmens, Korea alone (for unknown reasons) accounts for approximately 40% of the global total. History It remains unclear when, why and by whom the earliest dolmens were mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passage Grave
A passage grave or passage tomb consists of one or more burial chambers covered in earth or with stone, and having a narrow access passage made of large stones. These structures usually date from the Neolithic Age, and are found largely in Western Europe. When covered in earth, a passage grave is a type of burial mound which are found in various forms all over the world. When a passage grave is covered in stone, it is a type of cairn. Construction and design The building of passage graves was normally carried out with megaliths along with smaller stones. The earliest passage tombs seem to take the form of small dolmens, although not all dolmens are passage graves. The passage itself, in a number of notable instances, is aligned in such a way that the sun shines through the passage, into the chamber, at a significant point in the year, often at sunrise on the winter solstice or at sunset on the equinox. Many later passage tombs were constructed at the tops of hills or mountains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairn
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, càrn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
