Lighthouses
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 the advent of much cheaper, more sophisticated, and more 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 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 and promontories, unlike many mod ...

Eddystone Lighthouse
The Eddystone Lighthouse is a lighthouse on the Eddystone Rocks, south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea and are composed of Precambrian gneiss. View at 1:50000 scale The current structure is the fourth to be built on the site. The first lighthouse (Winstanley's) was swept away in a powerful storm, killing its architect and five other men in the process. The second (Rudyard's) stood for fifty years before it burned down. The third (Smeaton's) is renowned because of its influence on Lighthouse, lighthouse design and its importance in the development of concrete for building; its upper portions were re-erected in Plymouth as a monument. The first lighthouse, completed in 1699, was the world's first open ocean lighthouse, although the Cordouan Lighthouse off the western French coast preceded it as the first offshore lighthouse.

Smeaton's Tower
Smeaton's Tower is a redundant lighthouse, now a memorial to civil engineer John Smeaton, designer of the third and most notable Eddystone Lighthouse#Smeaton.27s lighthouse, Eddystone Lighthouse. A major step forward in lighthouse design, Smeaton's structure was in use from 1759 to 1877, until erosion of the ledge it was built upon forced new construction. The tower was largely dismantled and rebuilt on Plymouth Hoe in Plymouth, Devon, where it stands today. History Background England’s coasts are notorious for rough weather, dangerous seas and deathly obstacles. The Eddystone rocks are among them. Several attempts were made to place a marker on these reefs. The first attempt was called the Winstanley Lighthouse. After it was destroyed in the 1703 storm, a second one called the Rudyard lighthouse was built. This one was also destroyed, this time by a fire in 1755. Born in Austhorpe, Yorkshire, England in 1724, John Smeaton is considered the father of civil engineering. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse Of Alexandria
The Lighthouse of Alexandria, sometimes called the Pharos of Alexandria, was a lighthouse built by the Ptolemaic Kingdom of Ancient Egypt, during the reign of Ptolemy II Philadelphus (280–247 BC). It has been estimated to have been at least in overall height. One of the Seven Wonders of the Ancient World, for many centuries it was one of the tallest man-made structures in the world. The lighthouse was severely damaged by three earthquakes between 956 and 1303 AD and became an abandoned ruin. It was the third-longest surviving ancient wonder, after the Mausoleum at Halicarnassus and the extant Great Pyramid of Giza, surviving in part until 1480, when the last of its remnant stones were used to build the Citadel of Qaitbay on the site. In 1994, a team of French archaeologists dived in the water of Alexandria's Eastern Harbour and discovered some remains of the lighthouse on the sea floor. In 2016, the Ministry of State of Antiquities in Egypt had plans to turn submerged ruins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential.

Eddystone Rocks
The Eddystone or Eddystone Rocks are a seaswept and eroded group of rocks ranging southwest of Rame Head in Cornwall, England, United Kingdom. Although the nearest point on the mainland to the Eddystone is in Cornwall, the rocks fall within the city limits of Plymouth, and hence within the county of Devon. For centuries the rocks have been a hazard for the ships in the approaches to the English Channel and the port city of Plymouth. There have been four Eddystone Lighthouse, lighthouses on the Eddystone Rocks. Winstanley (two versions; the second replaced the top of the structure), Rudyard, Smeaton and finally the Douglass Lighthouse, which is the present one. When the Douglass Lighthouse was completed, the people of Plymouth paid for the dismantling of the Smeaton Lighthouse from the red rocks of Eddystone and its reassembly at Plymouth Hoe, where it is a popular Tourism, tourist attraction today.

Civil Engineer
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer" was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers, who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. ...
