Mount Batten
Mount Batten is a 24-metre (80-ft) tall outcrop of rock on a 600-metre (2000-ft) peninsula in Plymouth Sound, Devon, England, named after Sir William Batten (c.1600-1667), MP and Surveyor of the Navy; it was previously known as How Stert. After some redevelopment which started with the area coming under the control of the Plymouth Development Corporation for five years from 1993, the peninsula now has a marina and centre for sea sport. The Mount Batten Breakwater (also referred to as Cattewater Breakwater and, incorrectly, Mount Batten Pier) to the west doubles as a breakwater for the Cattewater and Sutton Harbour. It was built in 1881 by the Cattewater Commissioners and subsequently refurbished by the Plymouth Development Corporation opening formally in 1995. History Early history According to excavations reported by Barry Cunliffe in 1988, Mount Batten was the site of the earliest trade with Europe yet discovered in Bronze Age Britain, operating from the late Bronze A ...

Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...

Sailing Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Protection Of Wrecks Act 1973
The Protection of Wrecks Act 1973 (c. 33) is an Act of the Parliament of the United Kingdom which provides protection for designated shipwrecks. Section 1 of the act provides for wrecks to be designated because of historical, archaeological or artistic value. Section 2 provides for designation of dangerous sites. Wreck sites must have a known location in order to be designated. Designated wrecks are marked on admiralty charts and their physical location is sometimes marked by means of a buoy (sea mark). Information boards are often provided at nearby launch points on land. Wrecks designated by virtue of historical, archaeological or artistic value It is a criminal offence to interfere with a wreck designated under section 1 of the act without a licence. Navigation, angling and bathing are permitted provided this will not interfere with the wreck. A licence is required to dive at the wreck site. Separate licences are required for any disturbance, such as recovery of artifacts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merchant Ship
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in myriad sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albeit not the la ...

Cattewater Wreck
Cattewater Wreck is a wooden three-masted, skeleton-built vessel, one of many ships that have wrecked in Cattewater, Plymouth Sound, England. This wreck is close to the entrance of Sutton Harbour, its name is still unknown but it is believed to be from the 16th Century. It is a Protected Wreck managed by Historic England. History The wreck was found in 1973 when a dredger being used to deepen the Cattewater brought up timber wreckage and parts of some iron guns. An underwater investigation of the site in 1973 was instigated by the National Maritime Museum and the Department for the Environment. The investigation produced a provisional site plan and included the more controlled recovery of loose wreckage including concreted fragments of an iron muzzle loading cannon. The hull structure was the lowest section of hull from one end past the midships area, where the dredging work had caused extensive damage. Based on the assessments the site was recommended for designation under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scheduled Ancient Monument
In the United Kingdom, a scheduled monument is a nationally important archaeological site or historic building, given protection against unauthorised change. The various pieces of legislation that legally protect heritage assets from damage and destruction are grouped under the term "designation." The protection provided to scheduled monuments is given under the Ancient Monuments and Archaeological Areas Act 1979, which is a different law from that used for listed buildings (which fall within the town and country planning system). A heritage asset is a part of the historic environment that is valued because of its historic, archaeological, architectural or artistic interest. Only some of these are judged to be important enough to have extra legal protection through designation. There are about 20,000 scheduled monuments in England representing about 37,000 heritage assets. Of the tens of thousands of scheduled monuments in the UK, most are inconspicuous archaeological sites, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medieval Period
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Roma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isthmus
An isthmus (; ; ) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Isthmus vs land bridge vs peninsula ''Isthmus'' and ''land bridge'' are related terms, with isthmus having a broader meaning. A land bridge is an isthmus connecting Earth's major landmasses. The term ''land bridge'' is usually used in biogeology to describe land connections that used to exist between continents at various times and were important for migration of people and various species of animals and plants, e.g. Beringia and Doggerland. An isthmus is a land connection between two bigger landmasses, while a peninsula is rather a land protrusion which is connected to a bigger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g. the Panama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. Also erosion commonly ...

Plymouth Breakwater
Plymouth Breakwater is a stone breakwater protecting Plymouth Sound and the anchorages near Plymouth, Devon, England. It is wide at the top and the base is . It lies in about of water. Around 4 million tons of rock were used in its construction in 1812 at the then-colossal cost of £1.5 million (equivalent to £ today). History In 1806, as the Napoleonic Wars impended, Lord St. Vincent commissioned John Rennie and Joseph Whidbey to plan a means of making Plymouth Bay a safe anchorage for the Channel Fleet. These plans may have been taken from ones made by George Matcham (1753 – 3 February 1833). In 1811 came the order to begin construction; Whidbey was appointed Acting Superintending Engineer. This task required great engineering, organizational and political skills, as the many strictly technical challenges were complicated by the significant resources devoted to the project, from which various parties evidenced a desire for advantage. Nearly 4,000,000 (four million) ton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
