Treffgarne
Treffgarne ( cy, Trefgarn, or ''town of the rock'') is a small village and parish in Pembrokeshire, south-west Wales. It lies to the south of the Preseli Hills close to the Western Cleddau river, and close to the main A40 road from Fishguard to Haverfordwest. The area has an interesting local geology and evidence of mineral extraction at least as far back as Roman times. The present village is medieval in origin. Geology The village name is derived from the Welsh-language words ''tref'' ("town") and ''carn'' ("cairn, mound, rock"). The reference in this case is to the Treffgarne Rocks, a series of ancient Ordovician rhyolite volcanic plugs, now exposed, that form the Roche Rhyolite Group. A number of interesting minerals have been recorded including brookite crystals (titanium dioxide) and possibly tin. Small regular cavities can be found in the rocks where crystals of at least 1 cm (½") width once resided. Gold has also been found at the rocks from drillcores and placer gol ...

Wolfscastle
Wolfscastle ( cy, Casblaidd), also spelt Wolf's Castle, is a village and community in Pembrokeshire, between Haverfordwest and Fishguard, in southwest Wales. It was historically in the parish of St Dogwells. Geography and transport links Wolfscastle comprises two small villages; Wolfscastle proper, at the top of a hill, and Ford, situated in the river valley below. The remains of a motte and bailey castle lie in the upper village, a strategic location determined by its situation at the northern end of Treffgarne gorge. The village lies at the confluence of the Western Cleddau and the Anghof rivers, in the parish of St Dogwell's. The A40 road, the London to Fishguard trunk route, passes through Wolfscastle and provides the main transport route to and from the village, with a regular bus service connecting with the major towns of the area. The main railway line from Swansea to Fishguard Harbour passes through Ford. At one time, there was a station named at the point where ...

Western Cleddau
The River Cleddau ( cy, Afon Cleddau) consists of the Eastern and Western Cleddau rivers in Pembrokeshire, west Wales. They unite to form the Daugleddau estuary and the important harbour of Milford Haven. The name of the combined estuary – the Daugleddau – means “the two Cleddaus”. The name Cleddau, whilst seeming to be a plural ('-au' generally denotes plurality in Welsh) comes from the Welsh word ''cleddyf'' meaning 'sword' and refers perhaps to the manner in which both rivers are incised into the landscape of Pembrokeshire. A number of former Anglican parishes in the area have been combined to form the modern Church in Wales parish of Daugleddau in the Diocese of St Davids. Eastern Cleddau The Eastern Cleddau (Welsh: ''Cleddau Ddu'' meaning 'black') rises in the foothills of Mynydd Preseli at Blaencleddau in the parish of Mynachlog-ddu. It flows southwest through a broad moorland valley to Gelli Hill, where the River Syfynwy joins it. It then flows south throug ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Roman Britain
Roman Britain was the period in classical antiquity when large parts of the island of Great Britain were under occupation by the Roman Empire. The occupation lasted from AD 43 to AD 410. During that time, the territory conquered was raised to the status of a Roman province. Julius Caesar invaded Britain in 55 and 54 BC as part of his Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by other Celtic tribes during the British Iron Age and had been aiding Caesar's enemies. He received tribute, installed the friendly king Mandubracius over the Trinovantes, and returned to Gaul. Planned invasions under Augustus were called off in 34, 27, and 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells ('' musculi'') according to Suetonius, perhaps as a symbolic gesture to proclaim Caligula's victory over the sea. Three years later, Claudius directed four legi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Wales
The Roman era in the area of modern Wales began in 48 AD, with a military invasion by the imperial governor of Roman Britain. The conquest was completed by 78 AD, and Roman rule endured until the region was abandoned in 383 AD. The Roman Empire held a military occupation in most of Wales, except for the southern coastal region of South Wales, east of the Gower Peninsula, where there is a legacy of Romanisation in the region, and some southern sites such as Carmarthen, which was the civitas capital of the Demetae tribe. The only town in Wales founded by the Romans, Caerwent, is located in South Wales. Wales was a rich source of mineral wealth, and the Romans used their engineering technology to extract large amounts of gold, copper, and lead, as well as modest amounts of some other metals such as zinc and silver. The Roman campaigns of conquest in Wales appear in surviving ancient sources, who record in particular the resistance and ultimate conquest of two of the five na ...

Romano-British
The Romano-British culture arose in Britain under the Roman Empire following the Roman conquest in AD 43 and the creation of the province of Britannia. It arose as a fusion of the imported Roman culture with that of the indigenous Britons, a people of Celtic language and custom. Scholars such as Christopher Snyder believe that during the 5th and 6th centuries – approximately from 410 when the Roman legions withdrew, to 597 when St Augustine of Canterbury arrived – southern Britain preserved an active sub-Roman culture that survived the attacks from the Anglo-Saxons and even used a vernacular Latin when writing. Arrival of the Romans Roman troops, mainly from nearby provinces, invaded in AD 43, in what is now part of England, during the reign of Emperor Claudius. Over the next few years the province of Britannia was formed, eventually including the whole of what later became England and Wales and parts of Scotland.Kinder, H. & Hilgemann W.

Roman Road
Roman roads ( la, viae Romanae ; singular: ; meaning "Roman way") were physical infrastructure vital to the maintenance and development of the Roman state, and were built from about 300 BC through the expansion and consolidation of the Roman Republic and the Roman Empire. They provided efficient means for the overland movement of armies, officials, civilians, inland carriage of official communications, and trade goods. Roman roads were of several kinds, ranging from small local roads to broad, long-distance highways built to connect cities, major towns and military bases. These major roads were often stone-paved and metaled, cambered for drainage, and were flanked by footpaths, bridleways and drainage ditches. They were laid along accurately surveyed courses, and some were cut through hills, or conducted over rivers and ravines on bridgework. Sections could be supported over marshy ground on rafted or piled foundations.Corbishley, Mike: "The Roman World", page 50. Warwick Press, ...

Titanium Dioxide
Titanium dioxide, also known as titanium(IV) oxide or titania , is the inorganic compound with the chemical formula . When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble to water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at a price of $13.2 billion. Structure In all three of its main dioxides, titanium exhibits octahedral geometry, being bonded to six oxide anions. The oxides in turn are bonded to three Ti centers. The overall crystal structure of rutile is tetragonal in symmetry whereas anatase and brookite are orthorhombic. The oxygen substructures are all slight distort ...

Middle Ages
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 Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
