Lucan Bridge
Lucan Bridge ( ga, Droichead Leamhcáin) is a road bridge spanning the River Liffey in Lucan, County Dublin, Ireland. It joins Lucan's Main Street to the Lower Lucan Road, carrying traffic towards Clonsilla and the north, and the Strawberry Beds to the east. Designed by George Knowles (architect of Dublin's Fr. Mathew and O'Donovan Rossa Bridges), it was built in 1814. Constructed in collaboration with James Savage at a cost of more than £9,000, it replaced several previous bridges which had been carried away by floods. The bridge is the largest single span masonry arch bridge in Ireland, and is constructed from ashlar masonry with a span of 33 metres (110 feet) and a rise of 6.7 metres (22 feet). It is framed by iron balustraded parapets made by the ''Royal Phoenix ironworks'' of Parkgate Street in Dublin. Design and construction The first bridge built on this spot was a stone bridge laid down in the later years of the reign of King John (c. 1200). A subsequent bridge was ...

River Liffey
The River Liffey (Irish: ''An Life'', historically ''An Ruirthe(a)ch'') is a river in eastern Ireland that ultimately flows through the centre of Dublin to its mouth within Dublin Bay. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water and supports a range of recreational activities. Name Ptolemy's ''Geography'' (2nd century AD) described a river, perhaps the Liffey, which he labelled Οβοκα (''Oboka''). Ultimately this led to the name of the River Avoca in County Wicklow. The Liffey was previously named ''An Ruirthech'', meaning "fast (or strong) runner". The word ''Liphe'' (or ''Life'') referred originally to the name of the plain through which the river ran, but eventually came to refer to the river itself. The word may derive from the same root as Welsh ''llif'' (flow, stream), namely Proto-Indo-European ''lē̆i-4'', but Gearóid Mac Eoin has more recently proposed that it may derive from a n ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...

Voussoir
A voussoir () is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the keystone and the springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerist arches of the 16th century, beginning with the works of Giulio Romano, who also began the fashion for using voussoirs above rectangular openings, rather than a lintel (Palazzo Stati Maccarani, Rome, circa 1522). The word is a stonemason's term borrowed in Middle English from French verbs connoting a "turn" (''OED''). Each wedge-shaped voussoir ''turns aside'' the thrust of the mass above, transf ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilmainham
Kilmainham (, meaning " St Maighneann's church") is a south inner suburb of Dublin, Ireland, south of the River Liffey and west of the city centre. It is in the city's Dublin 8 postal district. The area was once known as Kilmanum. History In the Viking era, the monastery was home to the first Norse base ('' longphort'') in Ireland. The Kilmainham Brooch, a late 8th- or early 9th-century Celtic brooch of the "penannular" type (i.e. its ring does not fully close or is incomplete) was unearthed in an 18th-century excavation of a Viking burial place in Kilmainham, In the 12th century, the lands on the banks of the Liffey were granted to the Knights Hospitaller. Strongbow erected for them a castle about 2 kilometres or 1 mile distant from the Danish wall of old Dublin; and Hugh Tyrrel, first Baron Castleknock, granted them part of the lands which now form the Phoenix Park. The Knights of St. John of Jerusalem remained in possession of the land until the dissolution of the monaste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islandbridge
Island Bridge (), formerly Sarah or Sarah's Bridge, is a road bridge spanning the River Liffey, in Dublin, Ireland which joins the South Circular Road to Conyngham Road at the Phoenix Park. Island Bridge and the surrounding area (often known as Islandbridge) are so named because of the island formed here by the creation of a mill race towards the right bank while the main current flows to the left. The River Camac emerges from a tunnel further downstream towards Dublin Heuston railway station. History In 1577, during the reign of Queen Elizabeth, while Sir Henry Sidney was Lord Deputy of Ireland, an arched stone bridge was built here to replace an earlier structure nearby at Kilmainham. This bridge was swept away by a flood in 1787, and between 1791 and 1793 the replacement bridge, that is standing today, was constructed. The structure is a single 32-metre span ashlar masonry elliptical arch bridge and was originally named ''Sarah's Bridge'' after Sarah Fane, Countess of ...

Viscount De Vesci
Viscount de Vesci, of Abbeyleix in the Queen's County, now called County Laois (pronounced "leash"), is a title in the Peerage of Ireland. It was created in 1776 for Thomas Vesey, 2nd Baron Knapton and 3rd Baronet. The title Baron Knapton was created in the Peerage of Ireland in 1750 for the first Viscount's father, John Vesey, 2nd Baronet, who had earlier represented Newtownards (Parliament of Ireland constituency), Newtownards in the Irish House of Commons. The baronetcy, of Abbeyleix in the Queen's County, was created in the Baronetage of Ireland on 28 September 1698 for the first Baron's father, Reverend Thomas Vesey, 1st Baronet, Thomas Vesey, Bishop of Killaloe (1713–1714) and Bishop of Ossory (1714–1730).

John Of England
John (24 December 1166 – 19 October 1216) was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of , a document considered an early step in the evolution of the constitution of the United Kingdom. John was the youngest of the four surviving sons of King Henry II of England and Duchess Eleanor of Aquitaine. He was nicknamed John Lackland because he was not expected to inherit significant lands. He became Henry's favourite child following the failed revolt of 1173–1174 by his brothers Henry the Young King, Richard, and Geoffrey against the King. John was appointed Lord of Ireland in 1177 and given lands in England and on the continent. He unsuccessfully att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O'Donovan Rossa Bridge
O'Donovan Rossa Bridge () is a road bridge spanning the River Liffey in Dublin, Ireland, which joins Winetavern Street to Chancery Place (at the Four Courts) and the north quays. Replacing a short-lived wooden structure, the original masonry bridge on this site was built in 1684 as a five-span simple arch bridge, and named ''Ormonde Bridge''. In December 1802 this bridge was swept away during a severe storm. In 1813 construction started on a replacement bridge – the current structure – a little further west to the designs of James Savage and was opened in 1816. It consists of three elliptical arch spans in granite, with sculptured heads, similar to those on O'Connell Bridge, on the keystones. The heads represent ''Plenty'', the ''Liffey'', and ''Industry'' on one side, with ''Commerce'', ''Hibernia'' and ''Peace'' on the other. The balustrades are of cast iron. Opened as ''Richmond Bridge'' (named for Charles Lennox, 4th Duke of Richmond, Lord Lieutenant of Ireland), it w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
