List Of Orkney Islands
This is a list of Orkney islands in Scotland. The Orkney archipelago is located north of mainland Scotland and comprises over 70 islands and skerries, of which 20 are permanently inhabited. In addition to the Orkney Mainland there are three groups of islands. The North and South Isles lie respectively north and south of Mainland. The Pentland Skerries are a group of small islands in the Pentland Firth, a dangerous stretch of water between mainland Scotland and the larger islands of Orkney, through which run the strongest tidal streams in Britain. The Island of Stroma is often mistakenly included with the Orkney Islands, but is part of Caithness. The definition of an island used in this list is that it is 'land that is surrounded by seawater on a daily basis, but not necessarily at all stages of the tide, excluding human devices such as bridges and causeways'. There are four islands joined to the Orkney Mainland by a series of causeways known as the Churchill Barriers. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prisoners-of-war
A prisoner of war (POW) is a person who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610. Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from the enemy combatants still in the field (releasing and repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploiting them for their labour, recruiting or even conscripting them as their own combatants, collecting military and political intelligence from them, or indoctrinating them in new political or religious beliefs. Ancient times For most of human history, depending on the culture of the victors, enemy fighters on the losing side in a battle who had surrendered and been taken as prisoners of war could expect to be either slaughtered or enslaved.

European Marine Energy Centre
The European Marine Energy Centre (EMEC) Ltd is a UKAS accredited test and research center focusing on wave and tidal power development based in the Orkney Islands, UK. The centre provides developers with the opportunity to test full-scale grid-connected prototype devices in unrivalled wave and tidal conditions. In addition to EMEC's wave and tidal sites, EMEC has an onshore hydrogen production plant in Eday where green hydrogen is generated from surplus tidal and wind energy with a view of developing a hydrogen economy in Orkney. The operations are spread across five sites across Orkney: * Billia Croo wave energy test site, Mainland (wave power) * Fall of Warness tidal energy test site, off the island of Eday (tidal power) * Caldale Hydrogen Production Plant, on Eday * Scale wave test site at Scapa Flow, off St Mary's Bay * Scale tidal test site at Shapinsay Sound, off Head of Holland * Stromness (office and data facilities) EMEC was established by a grouping of public se ...

Lighthouse
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 reef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Of Neolithic Orkney
Heart of Neolithic Orkney refers to a group of Neolithic monuments found on the Mainland of the Orkney Islands, Scotland. The name was adopted by UNESCO when it proclaimed these sites as a World Heritage Site in December 1999. The site of patrimony currently consists of four sites: # Maes Howe – a unique chambered cairn and passage grave, aligned so that its central chamber is illuminated on the winter solstice. It was looted by Vikings who left one of the largest collections of runic inscriptions in the world. # Standing Stones of Stenness – the four remaining megaliths of a henge, the largest of which is 6 metres (19 ft) high. # Ring of Brodgar – a stone circle 104 metres in diameter, originally composed of 60 stones set within a circular ditch up to 3 metres deep and 10 metres wide, forming a henge monument. It has been estimated that the structure took 80,000 man-hours to construct. # Skara Brae – a cluster of eight houses making up Northe ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominat ...

Old Red Sandstone
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica/Laurussia. In Britain it is a lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a suite of sedimentary rocks deposited in a variety of environments during the Devonian but extending back into the late Silurian and on into the earliest part of the Car ...

Italian Chapel
The Italian Chapel is a highly ornate Catholic chapel on Lamb Holm in the Orkney Islands. It was built during World War II by Italian prisoners of war, who were housed on the previously uninhabited island while they constructed the Churchill Barriers to the east of Scapa Flow. Only the concrete foundations of the other buildings of the prisoner-of-war camp survive. The chapel was not completed until after the end of the war, and was restored in the 1960s and again in the 1990s. It is a popular tourist attraction, and a category A listed building. It is in the Roman Catholic Parish of Our Lady & St Joseph in Orkney, part of the Roman Catholic Diocese of Aberdeen. Mass is held in the chapel on the first Sunday of the summer months (April–September). Construction 550 Italian prisoners of war, captured in North Africa during World War II, were brought to Orkney in 1942. They worked on the construction of the Churchill Barriers, four causeways created to block access to Scapa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role ( commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
