Limestone Corner
Limestone Corner is an area of Hadrian's Wall (and associated defences) at its most northerly point, in present-day northern England. It represents the most northerly point of the Roman Empire, outside the two periods during which the Antonine Wall was occupied by the Roman military. Other notable features at Limestone Corner are the wall ditch at this point, which was never completely excavated, a Roman camp and the site of Milecastle 30. Also present is a trig point. The B6318 Military Road also runs through Limestone Corner, as does the Military Way, serving Milecastle 30. The Military Way is visible on the ground at this point, the most eastern point where this is the case. The name "Limestone Corner" is not an official geographical name for the area and does not appear on official maps; the hill on which it stands is known as Teppermoor Hill. Limestone Corner has become accepted through extensive usage. Geology Despite the name, the rock in the area is not actually ...

Northumberland
Northumberland () is a county in Northern England, one of two counties in England which border with Scotland. Notable landmarks in the county include Alnwick Castle, Bamburgh Castle, Hadrian's Wall and Hexham Abbey. It is bordered by land on three sides; by the Scottish Borders region to the north, County Durham and Tyne and Wear to the south, and Cumbria to the west. The fourth side is the North Sea, with a stretch of coastline to the east. A predominantly rural county with a landscape of moorland and farmland, a large area is part of Northumberland National Park. The area has been the site of a number of historic battles with Scotland. Name The name of Northumberland is recorded as ''norð hẏmbra land'' in the Anglo-Saxon Chronicle, meaning "the land north of the Humber". The name of the kingdom of ''Northumbria'' derives from the Old English meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. History ...

Boulder Clay
Boulder clay is an unsorted agglomeration of clastic sediment that is unstratified and structureless and contains gravel of various sizes, shapes, and compositions distributed at random in a fine-grained matrix. The fine-grained matrix consists of stiff, hard, pulverized clay or rock flour. Boulder clay is also know as either known as drift clay; till; unstratified drift, geschiebelehm (German); argile á blocaux (French); and keileem (Dutch).Charlesworth, J. K., 1957.

Hadrian's Wall Path
Hadrian's Wall Path is a long-distance footpath in the north of England, which became the 15th National Trail in 2003. It runs for , from Wallsend on the east coast of England to Bowness-on-Solway on the west coast. For most of its length it is close to the remains of Hadrian's Wall, the defensive wall built by the Romans on the northern border of their empire. This is now recognised as part of the " Frontiers of the Roman Empire" World Heritage Site. Path description Though muddy in places, the walking is relatively easy, as the highest point on the path is only 345 m (1130 ft) high and for much of its length the path is more or less flat. Most of the Wall runs through remote countryside but there are sections that pass through the cities and suburbs of Newcastle and Carlisle. The path is well signposted. For most of the walk there are many signs of human activity, and many other walkers in summer. Though there are villages and farms near to the path, there ar ...

Retriangulation Of Great Britain
__NOTOC__ The retriangulation of Great Britain was a triangulation project carried out between 1935 and 1962 that sought to improve the accuracy of maps made of Great Britain. Data gathered from the retriangulation replaced data gathered during the Principal Triangulation of Great Britain, which had been performed between 1783 and 1851. History The retriangulation was begun in 1935 by the Director General of the Ordnance Survey, Major-General Malcolm MacLeod. It was directed by the cartographer and mathematician Martin Hotine, head of the Trigonometrical and Levelling Division. A problem during the Principal Triangulation was that the exact locations of surveying stations were not always rediscoverable, relying on buried markers and unreliable local knowledge. To overcome this, a network of permanent surveying stations was built, most familiarly the concrete triangulation pillars (about 6,500 of them) found on many British Isles hill and mountain tops, but there were many othe ...

Trig Pillar At Limestone Corner - Geograph
Trigonometry () is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. Trigonometry is known for its many identities. These trigonometric identities are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful form of an expression, or to solve an equation. History Sumerian astronomers studied angle measure, using a division of circles into 360 degrees. They, and later the Babylonians, studied the ratios of the sides of ...

Castra
In the Roman Republic and the Roman Empire, the Latin word ''castrum'', plural ''castra'', was a military-related term. In Latin usage, the singular form ''castrum'' meant 'fort', while the plural form ''castra'' meant 'camp'. The singular and plural forms could refer in Latin to either a building or plot of land, used as a fortified military base.. Included is a discussion about the typologies of Roman fortifications. In English usage, ''castrum'' commonly translates to "Roman fort", "Roman camp" and "Roman fortress". However, scholastic convention tends to translate ''castrum'' as "fort", "camp", "marching camp" or "fortress". Romans used the term ''castrum'' for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments, and "marching" forts. The diminutive form ''castellum'' was used for fortlets, typically occupied by a detachment of a cohort or a '' centuria''. For a list of known castr ...

Ditch (fortification)
In military engineering, a ditch is an obstacle designed to slow down or break up an attacking force, while a trench is intended to provide cover to the defenders. In military fortifications the side of a ditch farthest from the enemy and closest to the next line of defence is known as the scarp while the side of a ditch closest to the enemy is known as the counterscarp. Uses In early fortifications, ditches were often used in combination with ramparts to slow down the enemy whilst defensive fire could be brought to bear from the relative protection afforded by the rampart and possibly the palisade. In medieval fortification, a ditch was often constructed in front of a defensive wall to hinder mining and escalade activities from an attacker. When filled with water, such a defensive ditch is called a moat. However, moats may also be dry. Later star forts designed by military engineers like Vauban, comprised elaborate networks of ditches and parapets, carefully calculated ...

Vallum
Vallum is either the whole or a portion of the fortifications of a Roman camp. The vallum usually comprised an earthen or turf rampart ( Agger) with a wooden palisade on top, with a deep outer ditch (fossa). The name is derived from '' vallus'' (a stake), and properly means the palisade which ran along the outer edge of the top of the agger, but is usually used to refer to the whole fortification. Characteristics The stake-like valli (χάρακες) of which the vallum palisade was composed are described by Polybius (xviii.18.1, Excerpt. Antiq. xvii.14) and Livy (Liv. xxxiii.5), who make a comparison between the vallum of the Greeks and that of the Romans, very much to the advantage of the latter. Both used for valli young trees or arms of larger trees, with the side branches on them; but the valli of the Greeks were much larger and had more branches than those of the Romans, which had either two or three, or at the most four branches, and these generally on the same side.

Berm
A berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line, a border/ separation barrier for navigation, good drainage, industry, or other purposes. Etymology The word is one of Middle Dutch and came into usage in English via French. Military use History In medieval military engineering, a berm (or berme) was a level space between a parapet or defensive wall and an adjacent steep-walled ditch or moat. It was intended to reduce soil pressure on the walls of the excavated part to prevent its collapse. It also meant that debris dislodged from fortifications would not fall into (and fill) a ditch or moat. In the trench warfare of World War I, the name was applied to a similar feature at the lip of a trench, which served mainly as an elbow-rest for riflemen. Modern usage In modern military engineering, a berm is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallum (Hadrian's Wall)
The Vallum is a huge earthwork associated with Hadrian's Wall in England. Unique on any Roman frontier, it runs practically from coast to coast to the south of the wall. The earliest surviving mention of the earthwork is by Bede (''Historia ecclesiastica gentis Anglorum'', I.12), who refers to a ''vallum'', or earthen rampart, as distinct from the wall, or ''murus''; the term is still used despite the fact that the essential element is a ditch, or ''fossa''. It was long thought that the Vallum predated the stone wall, whose most elaborate phasing was presented in 1801 by William Hutton, who thought, wrongly, that the south vallum mound and the marginal mound, with a ditch between, were the work of Agricola, that the vallum ditch and north mound were added by Hadrian, and that the stone wall was the work of Severus. In fact all these elements date to Hadrian's reign, with the stone wall having been built first. Layout and course The Vallum comprises a ditch, nominally wide and ...

Milecastle 26
Milecastle 26 (Planetrees) was a milecastle of the Roman Hadrian's Wall. Its position is slightly to the south of, but mostly covered by the B6318 Military Road., and it is located around east of the B6318 Military Road's junction with the A6079. No visible traces exist currently. The dimensions are the same as Milecastles 23, 24, and 25. Construction Measuring across, Milecastle 26 was a long-axis milecastle with unknown gateway type. Such milecastles were thought to have been constructed by the Legio VI Victrix who were based in Eboracum (York). A causeway over the wall ditch (not necessarily primary) may have existed at the location of the milecastle. The curtain wall is broad at this point, though changes to narrow gauge between here and Turret 26A, at an extant section of the curtain wall known as Planetrees. Also, in 1956, two iron wedges for splitting stones ( long) were discovered in the rubble and mortar core behind the north facing stones of the wall ...
