Black Nore Lighthouse
Black Nore Lighthouse (also known as Blacknore Point Lighthouse) at Portishead, Somerset, England, was built in 1894. It is a Grade II listed building. Description The metal white-painted lighthouse was built by Trinity House to guide shipping in the Severn Estuary as it made its way in and out of Bristol Harbour. Before the light was decommissioned the lens array (a rotating fourth-order 250 mm biform optic) flashed twice every ten seconds. History The light was first lit on 19 April 1894. Up until World War II the lighthouse was lit by gas, supplied from the gas main and stored in adjacent tanks. To begin with it displayed an occulting light (eclipsed twice in quick succession every twenty seconds) with a visible range of . The rotating optic was installed in 1908 when the light characteristic was changed to group flashing (twice every ten seconds). Its drive mechanism was wound daily by the Ashford Family, on whose land it was built, until 1941 when the light was conve ...

Portishead, Somerset
Portishead () is a coastal village on the Severn Estuary, 8 miles (12 km) to the west of Bristol, but within the unitary authority, unitary district of North Somerset, which falls within the Ceremonial counties of England, ceremonial county of Somerset, England. It has a population of around 25,000, with a growth rate considerably in excess of surrounding towns. Portishead has a long history as a fishing port. As a Royal Manor it expanded rapidly during the early 19th century around the docks, with supporting transport infrastructure. A Portishead power station, power station and chemical works were added in the 20th century, but the dock and industrial facilities have since closed and been redeveloped into a marina and residential areas. Portishead was also the telephone control centre used by British Telecom (BT) for non-direct dialled calls to maritime vessels, a service known as Portishead Radio. The town's population is expanding, and Portishead is now primarily a dormi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Listed Building
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Heritage
English Heritage (officially the English Heritage Trust) is a charity that manages over 400 historic monuments, buildings and places. These include prehistoric sites, medieval castles, Roman forts and country houses. The charity states that it uses these properties to "bring the story of England to life for over 10 million people each year". Within its portfolio are Stonehenge, Dover Castle, Tintagel Castle and the best preserved parts of Hadrian's Wall. English Heritage also manages the London Blue Plaque scheme, which links influential historical figures to particular buildings. When originally formed in 1983, English Heritage was the operating name of an executive non-departmental public body of the British Government, officially titled the Historic Buildings and Monuments Commission for England, that ran the national system of heritage protection and managed a range of historic properties. It was created to combine the roles of existing bodies that had emerged from a long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Severn Estuary
The Severn Estuary ( cy, Aber Hafren) is the estuary of the River Severn, flowing into the Bristol Channel between South West England and South Wales. Its high tidal range, approximately , means that it has been at the centre of discussions in the UK regarding renewable energy. Geography Definitions of the limits of the Severn Estuary vary. At the upstream boundary, the tidal limit of the river is at Gloucester. Downstream, the International Hydrographic Organization places the boundary between the estuary and the open sea of the Bristol Channel at a line between Sand Point, Somerset (immediately north of Weston-super-Mare) and Lavernock Point (immediately south of Penarth in south Wales). This definition is used by the Severn Estuary Partnership and Visit England. A narrower definition adopted for navigation purposes by some maps includes only the area downstream of the Second Severn Crossing near Severn Beach, South Gloucestershire. The definition used on Admiralty Chart SC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Harbour
Bristol Harbour is the harbour in the city of Bristol, England. The harbour covers an area of . It is the former natural tidal river Avon through the city but was made into its current form in 1809 when the tide was prevented from going out permanently. A tidal by-pass was dug for 2 miles through the fields of Bedminster for the river, known as the "River Avon New Cut", "New Cut", or simply "The Cut". It is often called the Floating Harbour as the water level remains constant and it is not affected by the state of the tide on the river in the Avon Gorge, The New Cut or the natural river southeast of Temple Meads to its source. Netham Lock at the east end of the 1809 Feeder Canal is the upstream limit of the floating harbour. Beyond the lock is a junction: on one arm the navigable River Avon continues upstream to Bath, and on the other arm is the tidal natural River Avon. The first of the floating harbour, downstream from Netham Lock to Totterdown Basin, is an artificial canal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fourth Order Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Occulting Light
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, " ...
