Defensible Barracks, Pembroke Dock
The Defensible Barracks at Pembroke Dock, is a Grade II* listed, Victorian-era fortification and barracks in Pembrokeshire, South Wales. It is a 20-sided stone fort surrounded by a dry moat with masonry walls. A parade ground occupies the centre of the fort. It was built in the mid-1840s to house the Royal Marines based in Pembroke Dockyard and to protect the dockyard. History The barracks was built between 1841 and 1846 to house the dockyard's garrison of Royal Marines and to cover the landward side of the dockyard from an infantry assault. It was probably the last trace bastion fort built in Europe. Prior to the Defensible Barracks' construction, the Royal Marines were housed in the hulked 74-gun ship, , that had been deliberately run aground in 1832. The barracks was acquired by a private developer, with plans to convert it into residential accommodation, in September 2019. Description The barracks is in the form of a square bastion trace with four two-storey, barrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembroke Dock
Pembroke Dock ( cy, Doc Penfro) is a town and a community in Pembrokeshire, South West Wales, northwest of Pembroke on the banks of the River Cleddau. Originally Paterchurch, a small fishing village, Pembroke Dock town expanded rapidly following the construction of the Royal Navy Dockyard in 1814. The Cleddau Bridge links Pembroke Dock with Neyland. After Haverfordwest and Milford Haven, Pembroke Dock is the third-largest town in Pembrokeshire being more populous than neighbouring Pembroke. History The natural harbour (now the Milford Haven Waterway) offering shelter from the prevailing south-westerly winds, has probably been used for many thousands of years. From maps, the first evidence of settlement is the name of the Carr Rocks at the entrance, derived from the Norse-language ''Skare'' for rock. From 790 until the Norman Invasion (1066) the estuary was used by the Vikings. During one visit, either in 854 or in 878, maybe on his way to the Battle of Cynuit, the Viking c ...

Pembroke Dockyard
Pembroke Dockyard, originally called Pater Yard, is a former Royal Navy Dockyard in Pembroke Dock, Pembrokeshire, Wales. History It was founded in 1814, although not formally authorized until the Prince Regent signed the necessary Order in Council on 31 October 1815, and was known as ''Pater Yard'' until 1817. The Mayor of Pembroke had requested the change "in deference to the town of Pembroke some distant". The site selected for the dockyard was greenfield land and the closest accommodations were in Pembroke. Office space was provided by the old frigate after she was beached. The Royal Marine garrison was housed in the hulked 74-gun ship, , after she was run aground in 1832. Many of the workmen commuted by boat from nearby communities until Pembroke Dock town was built up. In 1860 the dockyard's policing was transferred to the new No. 4 Division of the Metropolitan Police, which remained in that role until the 1920s. After the end of the First World War, the dockyard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forts In Pembrokeshire
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted ...

Arrowslit
An arrowslit (often also referred to as an arrow loop, loophole or loop hole, and sometimes a balistraria) is a narrow vertical aperture in a fortification through which an archer can launch arrows or a crossbowman can launch bolts. The interior walls behind an arrow loop are often cut away at an oblique angle so that the archer has a wide field of view and field of fire. Arrow slits come in a variety of forms. A common one is the cross, accommodating the use of both the longbow and the crossbow. The narrow vertical aperture permits the archer large degrees of freedom to vary the elevation and direction of their bowshot, but makes it difficult for attackers to harm the archer since there is only a small target at which to aim. Balistraria, plural balistrariae, from balister, crossbowman can often be found in the curtain walls of medieval battlements beneath the crenellations. History The invention of the arrowslit is attributed to Archimedes during the siege of Syracuse in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counterscarp
A scarp and a counterscarp are the inner and outer sides, respectively, of a ditch or moat used in fortifications. Attackers (if they have not bridged the ditch) must descend the counterscarp and ascend the scarp. In permanent fortifications the scarp and counterscarp may be encased in stone. In less permanent fortifications, the counterscarp may be lined with paling fence set at an angle so as to give no cover to the attackers but to make advancing and retreating more difficult. If an attacker succeeds in breaching a wall a coupure can be dug on the inside of the wall to hinder the forlorn hope, in which case the side of the ditch farthest from the breached wall and closest to the centre of the fortification is also called the counterscarp. Counterscarp gallery These are tunnels or "galleries" that have been built behind the counterscarp wall inside the moat or ditch. Each gallery is pierced with loopholes for musketry, so that attacking forces that enter the moat can be dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drawbridge
A drawbridge or draw-bridge is a type of moveable bridge typically at the entrance to a castle or tower surrounded by a moat. In some forms of English, including American English, the word ''drawbridge'' commonly refers to all types of moveable bridges, such as bascule bridges, vertical-lift bridges and swing bridges, but this article concerns the narrower historical definition of the term where the bridge is used in a defensive structure. As used in castles or defensive structures, drawbridges provide access across defensive structures when lowered, but can quickly be raised from within to deny entry to an enemy force. Castle drawbridges Medieval castles were usually defended by a ditch or moat, crossed by a wooden bridge. In early castles the bridge might be designed to be destroyed or removed in the event of an attack, but drawbridges became very common. A typical arrangement would have the drawbridge immediately outside a gatehouse, consisting of a wooden deck with one ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gatehouse
A gatehouse is a type of fortified gateway, an entry control point building, enclosing or accompanying a gateway for a town, religious house, castle, manor house, or other fortification building of importance. Gatehouses are typically the most heavily armed section of a fortification, to compensate for being structurally the weakest and the most probable attack point by an enemy. There are numerous surviving examples in France, Austria, Germany, England and Japan. History Gatehouses made their first appearance in the early antiquity when it became necessary to protect the main entrance to a castle or town. Over time, they evolved into very complicated structures with many lines of defence. Strongly fortified gatehouses would normally include a drawbridge, one or more portcullises, machicolations, arrow loops and possibly even murder-holes where stones would be dropped on attackers. In some castles, the gatehouse was so strongly fortified it took on the function of a keep, som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Grounding
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground". When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety. As hazard Severe grounding applies extreme loads upon ship structures. In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties. Grounding accounts for about one-third of commercial ship accidents,Kit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
74-gun Ship
The "seventy-four" was a type of two- decked sailing ship of the line, which nominally carried 74 guns. It was developed by the French navy in the 1740s, replacing earlier classes of 60- and 62-gun ships, as a larger complement to the recently-developed 64-gun ships. Impressed with the performance of several captured French seventy-fours, the British Royal Navy quickly adopted similar designs, classing them as third rates. The type then spread to the Spanish, Dutch, Danish and Russian navies. The design was considered a good balance between firepower and sailing qualities. Hundreds of seventy-fours were constructed, becoming the dominant form of ship-of-the-line. They remained the mainstay of most major fleets into the early 19th century. From the 1820s, they began to be replaced by larger two-decked ships mounting more guns. However some seventy-fours remained in service until the late 19th century, when they were finally supplanted by ironclads. Standardising on a common ship s ...

Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) w ...

Trace Bastion
A bastion fort or ''trace italienne'' (a phrase derived from non-standard French, literally meaning ''Italian outline'') is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-fifteenth century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era. The design of the fort is normally a polygon with bastions at the corners of the walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain from positions protected from direct fire. Many bastion forts also feature cavaliers, which are raised secondary structures based entirely inside the primary structure. Origins Their predecessors, medieval fortresses, were usually placed on high hills. From there, arrows were shot at the enemies. The enemies' hope was to either ram the gate or cl ...

Royal Marines
The Corps of Royal Marines (RM), also known as the Royal Marines Commandos, are the UK's special operations capable commando force, amphibious light infantry and also one of the five fighting arms of the Royal Navy. The Corps of Royal Marines can trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and can trace their commando origins to the formation of the 3rd Special Service Brigade, now known as 3 Commando Brigade on 14 February 1942, during the Second World War. As a specialised and adaptable light infantry and commando force, Royal Marine Commandos are trained for rapid deployment worldwide and capable of dealing with a wide range of threats. The Corps of Royal Marines is organised into 3 Commando Brigade and a number of separate units, including 47 Commando (Raiding Group) Royal Marines, and a company-strength commitment to the Special Forces Support Group. The Corps operates in all environments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
