Ruvaal Lighthouse
The Ruvaal, Rhuvaal, or Rubh'a' Mhàil Lighthouse is a listed 19th century lighthouse, located at the north-eastern end of the island of Islay, in the Inner Hebrides off the west coast of Scotland. The active lighthouse marks the northern approaches to the Sound of Islay a narrow channel separating Islay from the adjacent island of Jura, and is one of the seven lighthouses operated by the Northern Lighthouse Board, which act as maritime aids to navigation on and around Islay. History The need for lights near the sound had been identified as early as 1835 by Robert Stevenson, with the Board of Trade requesting that the light should cover the Neva Rocks to the west. This requirement meant that a substantial tower was required. It was designed by the brothers David Stevenson and Thomas the sons of Robert, from the notable Stevenson lighthouse engineering family. Construction started in 1857 and it was completed in 1859. The total cost was £6,500 (equivalent to £ as of ). T ...

Islay
Islay ( ; gd, Ìle, sco, Ila) is the southernmost island of the Inner Hebrides of Scotland. Known as "The Queen of the Hebrides", it lies in Argyll just south west of Jura, Scotland, Jura and around north of the Northern Irish coast. The island's capital is Bowmore where the distinctive round Kilarrow Parish Church and a distillery are located. Port Ellen is the main port. Islay is the fifth-largest Scottish island and the eighth-largest List of islands of the British Isles, island of the British Isles, with a total area of almost . There is ample evidence of the prehistoric settlement of Islay and the first written reference may have come in the first century AD. The island had become part of the Gaelic Kingdom of Dál Riata during the Scotland in the Early Middle Ages, Early Middle Ages before being absorbed into the Norse Kingdom of the Isles. The later medieval period marked a "cultural high point" with the transfer of the Hebrides to the Kingdom of Scotland and the eme ...

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. Description The Fresnel lens redu ...

Lighthouses Completed In 1859
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs ...

Gazetteer For Scotland
The ''Gazetteer for Scotland'' is a gazetteer covering the geography, history and people of Scotland. It was conceived in 1995 by Bruce Gittings of the University of Edinburgh and David Munro of the Royal Scottish Geographical Society, and contains 25,870 entries as of July 2019. It claims to be "the largest dedicated Scottish resource created for the web". The Gazetteer for Scotland provides a carefully researched and editorially validated resource widely used by students, researchers, tourists and family historians with interests in Scotland. Following on from a strong Scottish tradition of geographical publishing, the ''Gazetteer for Scotland'' is the first comprehensive gazetteer to be produced for the country since Francis Groome's ''Ordnance Gazetteer of Scotland'' (1882-6) (the text of which is incorporated into relevant entries). The aim is not to produce a travel guide, of which there are many, but to write a substantive and thoroughly edited description of the count ...

Historic Environment Scotland
Historic Environment Scotland (HES) ( gd, Àrainneachd Eachdraidheil Alba) is an executive non-departmental public body responsible for investigating, caring for and promoting Scotland's historic environment. HES was formed in 2015 from the merger of government agency Historic Scotland with the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS). Among other duties, Historic Environment Scotland maintains more than 300 properties of national importance including Edinburgh Castle, Skara Brae and Fort George. History The responsibilities of HES were formerly split between Historic Scotland, a government agency responsible for properties of national importance, and the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS), which collected and managed records about Scotland's historic environment. Under the terms of a Bill of the Scottish Parliament published on 3 March 2014, the pair were dissolved and their functions transferred ...

List Of Lighthouses In Scotland
This is a list of lighthouses in Scotland. The Northern Lighthouse Board, from which much of the information is derived, are responsible for most lighthouses in Scotland but have handed over responsibility in the major estuaries to the port authorities. Many of the more minor lights are not shown. A lighthouse that is no longer operating is indicated by the date of closure in the ''operated by'' column. Where two dates are shown, the lighthouse has been rebuilt. Nearly all the lighthouses in this list were designed by and most were built by four generations of one family, including Thomas Smith, who was both the stepfather and father-in-law of Robert Stevenson. Robert's sons and grandsons not only built most of the lights, often under the most appalling of conditions, but pioneered many of the improvements in lighting and signalling that cut down the enormous loss of life in shipping around the coasts of Scotland. The table may be sorted by any column by clicking on the headin ...

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, ...

Colonsay
Colonsay (; gd, Colbhasa; sco, Colonsay) is an island in the Inner Hebrides of Scotland, located north of Islay and south of Mull. The ancestral home of Clan Macfie and the Colonsay branch of Clan MacNeil, it is in the council area of Argyll and Bute and has an area of . Aligned on a south-west to north-east axis, it measures in length and reaches at its widest point. Geology The Colonsay Group, which takes its name from the island, is an estimated sequence of mildly metamorphosed Neoproterozoic sedimentary rocks that also outcrop on the islands of Islay and Oronsay and the surrounding seabed. The sequence has been correlated with the Grampian Group, the oldest part of the Dalradian Supergroup. It includes the meta wackes of the Oronsay Greywacke Formation, the sandstones of the Dun Gallain Grit Formation, the metasandstones and metamudstones of the Machrins Arkose, Kilchattan and Milbuie formations, the sandstones and phyllites of the Kiloran Flags Formation and the phy ...

Colonsay House
Colonsay House is a Georgian country house on the island of Colonsay, in the Scottish Inner Hebrides. It is a Category B listed building, and is now in the ownership of the Barons Strathcona. The gardens are open to the public, and are listed on the ''Inventory of Gardens and Designed Landscapes in Scotland'', the national listing of historic gardens. Colonsay House The central part of the house, was first built by the McNeill family in 1722. It is a medium-sized Georgian country house on the island of Colonsay, in the Inner Hebrides of Scotland. It is often said in twentieth-century sources to have been built on the site of an earlier abbey, but there is no evidence in any charter or list of Scottish monasteries of any abbey (or any other monastic foundation) having been here. Nor is there any mention in any medieval witness-list of a prior or abbot of Kiloran. We must regard the story as a fable, though the church (and the island as a whole) did belong to the abbey of Iona ...
