Nelson Monument, Edinburgh
The Nelson Monument is a commemorative tower in honour of Vice Admiral Horatio Nelson, located in Edinburgh, Scotland. It is situated on top of Calton Hill, and provides a dramatic termination to the vista along Princes Street from the west. The monument was built between 1807 and 1816 to commemorate Nelson's victory over the French and Spanish fleets at the Battle of Trafalgar in 1805, and his own death at the same battle. In 1852 a mechanized time ball was added, as a time signal to shipping in Leith harbour. The time ball is synchronized with the One O'Clock Gun firing from Edinburgh Castle. The monument was restored in 2009. The Royal Navy's White Ensign and signal flags spelling out Nelson's famous message " England expects that every man will do his duty" are flown from the monument on Trafalgar Day each year. History The monument was constructed at the highest point of Calton Hill, at above sea-level, replacing an earlier mast used to send signals to sh ...

Royal Commission On The Ancient And Historical Monuments Of Scotland
The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) was an executive non-departmental public body of the Scottish Government that was "sponsored" inanced and with oversightthrough Historic Scotland, an executive agency of the Scottish Government. As one of the country's National Collections, it was responsible for recording, interpreting and collecting information about the built and historic environment. This information, which relates to buildings, sites, and ancient monuments of archaeological, architectural and historical interest (including maritime sites and underwater constructions), as well as historical aspects of the landscape, was then made available to the public, mainly at no cost. It was established (shortly ahead of parallel commissions for Wales and England) by a Royal Warrant of 1908, which was revised in 1992. The RCAHMS merged with government agency Historic Scotland to form Historic Environment Scotland, a new executive no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Chronometer
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), or in the modern world its successor Coordinated Universal Time (UTC), and the time at the current location found from observations of celestial bodies. When first developed in the 18th century, it was a major technical achievement, as accurate knowledge of the time over a long sea voyage was vital for effective navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man, John Harrison, spanning 31 years of persistent experimentation and testing that revolutionized naval (and later aerial) navigation and enabling the Age of Discovery and Colonialism to accelerate. The term '' chronometer'' was coined from the Greek words '' χρόνος (chronos)'' (meaning time) and '' meter'' (meaning measure) in 171 ...

Firth Of Forth
The Firth of Forth () is the estuary, or firth, of several Scottish rivers including the River Forth. It meets the North Sea with Fife on the north coast and Lothian on the south. Name ''Firth'' is a cognate of ''fjord'', a Norse word meaning a narrow inlet. ''Forth'' stems from the name of the river; this is ''*Vo-rit-ia'' (slow running) in Proto-Celtic, yielding '' Foirthe'' in Old Gaelic and '' Gweryd'' in Welsh. It was known as ''Bodotria'' in Roman times. In the Norse sagas it was known as the ''Myrkvifiörd''. An early Welsh name is ''Merin Iodeo'', or the "Sea of Iudeu". Geography and economy Geologically, the Firth of Forth is a fjord, formed by the Forth Glacier in the last glacial period. The drainage basin for the Firth of Forth covers a wide geographic area including places as far from the shore as Ben Lomond, Cumbernauld, Harthill, Penicuik and the edges of Gleneagles Golf Course. Many towns line the shores, as well as the petrochemical complexes at G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Signal
A time signal is a visible, audible, mechanical, or electronic signal used as a reference to determine the time of day. Church bells or voices announcing hours of prayer gave way to automatically operated chimes on public clocks; however, audible signals (even signal guns) have limited range. Busy seaports used a visual signal, the dropping of a ball, to allow mariners to check the chronometers used for navigation. The advent of electrical telegraphs allowed widespread and precise distribution of time signals from central observatories. Railways were among the first customers for time signals, which allowed synchronization of their operations over wide geographic areas. Dedicated radio time signal stations transmit a signal that allows automatic synchronization of clocks, and commercial broadcasters still include time signals in their programming. Today, global navigation satellite systems ( GNSS) radio signals are used to precisely distribute time signals over much of th ...

Time Ball On The Nelson Monument, Edinburgh
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Cape St Vincent (1797)
The Battle of Cape St. Vincent (14 February 1797) was one of the opening battles of the Anglo-Spanish War (1796–1808), as part of the French Revolutionary Wars, where a British fleet under Admiral Sir John Jervis defeated a greatly superior Spanish fleet under Admiral Don José de Córdoba y Ramos near Cape St. Vincent, Portugal. Background After the signing of the Treaty of San Ildefonso in 1796 allying Spanish and French forces against Great Britain, the British navy blockaded Spain in 1797, impairing communications with its Spanish Empire. The Spanish declaration of war on Britain and Portugal in October 1796 made the British position in the Mediterranean untenable. The combined Franco-Spanish fleet of 38 ships of the line heavily outnumbered the British Mediterranean Fleet of fifteen ships of the line, forcing the British to evacuate their positions in first Corsica and then Elba. Early in 1797, the Spanish fleet of 27 ships of the line, which were supposed to join ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS San Josef (1797)
HMS ''San Josef'' was a 114-gun first-rate ship of the line of the Royal Navy. Originally built at Ferrol in Galicia for the Spanish Navy in 1782–83, she was captured from the Spanish Navy at the Battle of Cape St Vincent on 14 February 1797 (when she was still named in Spanish ''San José''). In 1809 she served as the flagship of Admiral John Thomas Duckworth. Battle of Cape St Vincent The ''San José'' was among the Spanish fleet during the battle, during which HMS ''Captain'', under the command of Captain Horatio Nelson came out of the line to attack the ''San Nicolás''. After exchanging fire, Nelson led his forces aboard the ''San Nicolás''. While the English were fighting their way aboard the ''San José'' continued to fire upon the ''Captain'' and the ''San Nicolás''. The ''San José'' then fell upon the ''San Nicolás'' and their rigging became tangled. Trapped, the men from the ''San José'' continued to fire on the British boarding parties with muskets and pi ...

Anno Domini
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the ...

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 worsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castellation
A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e., a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed " crenels" (also known as ''carnels'', or '' embrasures''), and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation. The function of battlements in war is to protect the defenders by giving them something to hide behind, from which they can pop out to launch their own missiles. A defensive building might be designed and built with battlements, or a manor house might be fortified by adding battlements, where no parapet previously existed, or cutting crenellations into its existing parapet wall. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Bonnar
Thomas Bonnar ( d.1847) was a Scottish interior designer and architect of note, working in the Edinburgh area. He is particularly remembered for his outstanding ceilings. Thomas was father to William Bonnar RSA (1800-1853), artist, and Thomas Bonnar (1810-1873) engraver, who collaborated with William on several works. The group are also known by the family company name of Bonnar & Co. Life He was born in Edinburgh around 1770, the son of John Bonnar who had created the ceilings in Penicuik House. His family lived in a then new house at 6 South St David Street during his teenage years. He was appointed as a burgess of the city in 1795 and a "sworn measurer" in 1807 and Superintendent of Works for the city in 1809, operating from the Magdalene Chapel in the Cowgate. From 1810 he acted as architect and surveyor to George Heriot’s School. He lost all public posts in January 1819 due to a bungled execution on 30 December (part of his wide scope of duties) which ended in ...
