Promontory
A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula). Most promontories either are formed from a hard ridge of rock that has resisted the erosive forces that have removed the softer rock to the sides of it, or are the high ground that remains between two river valleys where they form a confluence. One type of promontory is a headland, or head. Promontories in history Located at the edge of a landmass, promontories offer a natural defense against enemies, as they are often surrounded by water and difficult to access. Many ancient and modern forts and castles have been built on promontories for this reason. One of the most famous examples of promontory forts is the Citadel of Namur in Belgium. Located at the confluence of the Meuse and Sambre rivers, the citadel has been a prime fortified location since the 10th century. The surrounding rivers act as a natural moat, making it difficult for enemies to access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Promontory Fort
A promontory fort is a fortification, defensive structure located above a steep cliff, often only connected to the mainland by a small neck of land, thus using the topography to reduce the Rampart (fortification), ramparts needed. The oldest known promontory fort is Amnya I in Siberia which was established as a fortified site in the late 7th millennium BC. Although their dating is problematic, most seem to date to the Iron Age. They are mainly found in Ireland, Brittany, the Orkney Islands, the Isle of Man, Devon, the Channel Islands and Cornwall. Ireland Only a few Irish promontory forts have been excavated and most date to the Iron Age, though some, like Dunbeg Fort (County Kerry) might have originated in the Bronze Age. Others, like Dalkey Island (County Dublin) contain imported Eastern Mediterranean pottery and have been reoccupied and changed in the early medieval period. Some, like Doonmore (near Dingle, County Kerry) are associated with the Middle Ages. Dunbeg contains an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("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 cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or 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 as a bor ...

Headland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle
A castle is a type of fortification, fortified structure built during the Middle Ages predominantly by the nobility or royalty and by Military order (monastic society), military orders. Scholars usually consider a ''castle'' to be the private fortified house, fortified residence of a lord or noble. This is distinct from a mansion, palace, and villa, whose main purpose was exclusively for ''pleasance'' and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain wall (fortification), curtain walls, arrowslits, and portcullises, were commonplace. European-style castles originated in the 9th and 10th centuries after the fall of the Carolingian Empire, which resulted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Duquesne
Fort Duquesne ( , ; originally called ''Fort Du Quesne'') was a fort established by the French in 1754, at the confluence of the Allegheny and Monongahela rivers. It was later taken over by the British, and later the Americans, and developed as Pittsburgh in the U.S. state of Pennsylvania. Fort Duquesne was destroyed by the French before its British conquest during the Seven Years' War, known as the French and Indian War on the North American front. The British replaced it, building Fort Pitt between 1759 and 1761. The site of both forts is now occupied by Point State Park, where the outlines of the two forts have been laid in granite slabs. History 18th century Fort Duquesne, built at the confluence of the Allegheny and Monongahela rivers which forms the Ohio River, was considered strategically important for controlling the Ohio Country,"The Diaries of George Washington, Vol. 1", Donald Jackson, ed., Dorothy Twohig, assoc. edLibrary of Congress American Memory site/ ...

Allegheny River
The Allegheny River ( ; ; ) is a tributary of the Ohio River that is located in western Pennsylvania and New York (state), New York in the United States. It runs from its headwaters just below the middle of Pennsylvania's northern border, northwesterly into New York, then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio at Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers. This shallow river has been made navigable upstream from Pittsburgh to East Brady, Pennsylvania, East Brady by a series of locks and dams that were constructed during the early 20th century. A 24-mile-long portion of the upper river in Warren County, Pennsylvania, Warren and McKean County, Pennsylvania, McKean c ...

Monongahela River
The Monongahela River ( , ), sometimes referred to locally as the Mon (), is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in north-central West Virginia and Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river includes a series of locks and dams that makes it navigable. Etymology The Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Indian tongue the name of this river was ''Mechmenawungihilla'' (alternatively spelled ''Menawngihella''), which signifies a high bank, which is ever washed o ...

Fort Pitt was a fort built by British forces between 1759 and 1761 during the French and Indian War at the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, where the Ohio River is formed in western Pennsylvania (modern day Pittsburgh). It was near (but not directly on) the site of Fort Duquesne, a French colonial fort built in 1754 as tensions increased between Kingdom of Great Britain, Great Britain and France in both Europe and North America. The French destroyed Fort Duquesne in 1758 when they retreated under British attack.
