Pharos
The Lighthouse of Alexandria, sometimes called the Pharos of Alexandria (; Ancient Greek: ὁ Φάρος τῆς Ἀλεξανδρείας, contemporary Koine ), 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 1323 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 dove into the water of Alexandria's Eastern Harbour and discovered some remains of the lighthouse on the sea ...

Alexandria
Alexandria ( or ; ar, ٱلْإِسْكَنْدَرِيَّةُ ; grc-gre, Αλεξάνδρεια, Alexándria) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria, which ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about along the northern coast of Egypt, and is the largest city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heptastadion
The Heptastadion (Greek: Ὲπταστάδιον) was a giant causeway, often referred to as a mole or a dyke built by the people of Alexandria, Egypt in the 3rd century BC during the Ptolemaic period. The Heptastadion was created to link Pharos Island to the mainland coast and given a name based on its length (Heptastadion is Greek for "seven stadia"— ''hepta'' meaning seven, and a '' stadion'' being a Greek unit of length measuring approximately ). Overall it was more than three-quarters of a mile long. History Alexander the Great founded of the city of Alexandria in April 331 BC on the site of the small fishing village of Rhacotis as the marine base for his fleet. The city was built on a narrow limestone ridge opposite to Pharos Island where the Pharos lighthouse would later stand. Forces under Alexander's command cleared the sand and silt deposits which made the port unnavigable, and Alexander's engineer Dinocrates linked the port of Alexandria and the island of Pharos wi ...

Mole (architecture)
A mole is a massive structure, usually of stone, used as a pier, breakwater, or a causeway separating two bodies of water. The word comes from Middle French ''mole'', ultimately from Latin ''mōlēs'', meaning a large mass, especially of rock; it has the same root as molecule and mole, the chemical unit of measurement. A mole may have a wooden structure built on top of it that resembles a wooden pier. The defining feature of a mole, however, is that water cannot freely flow underneath it, unlike a true pier. The oldest known mole is at Wadi al-Jarf, an ancient Egyptian harbor complex on the Red Sea, constructed ca. 2500 BCE. San Francisco Bay Area In the San Francisco Bay Area in California, there were several moles, combined causeways and wooden piers or trestles extending from the eastern shore and utilized by various railroads, such as the Key System, Southern Pacific Railroad (two), and Western Pacific Railroad: the Alameda Mole, the Oakland Mole, and the Western Pac ...

Tallest Man-made Structures In The World
The world's tallest human-made structure is the Burj Khalifa in Dubai (of the United Arab Emirates). The building gained the official title of "tallest building in the world" and the tallest self-supported structure at its opening on January 9, 2010. Burj Khalifa was developed by Emaar properties, designed by Skidmore, Owings and Merrill and built by BESIX, Samsung Construction and Arabtec. The second-tallest self-supporting structure and the tallest tower in the world is the Tokyo Skytree. The tallest guyed structure is the KVLY-TV mast at 1987 feet. The Council on Tall Buildings and Urban Habitat, an organization that certifies buildings as the "World's Tallest", recognizes a building only if at least 49% of its height is made up of floor plates containing habitable floor area. Structures that do not meet this criterion, such as the CN Tower, are defined as "towers". There are dozens of radio and television broadcasting towers which measure over 600 metres (about ...

Seven Wonders Of The Ancient World
The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC. While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, with the others being destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. Background Alexande ...

Geographica
The ''Geographica'' (Ancient Greek: Γεωγραφικά ''Geōgraphiká''), or ''Geography'', is an encyclopedia of geographical knowledge, consisting of 17 'books', written in Greek and attributed to Strabo, an educated citizen of the Roman Empire of Greek descent. There is a fragmentary palimpsest dating to the fifth century. The earliest manuscripts of books 1–9 date to the tenth century, with a 13th-century manuscript containing the entire text. Title of the work Strabo refers to his ''Geography'' within it by several names: * geōgraphia, "description of the earth" * chōrographia, "description of the land" * periēgēsis, "an outline" * periodos gēs, "circuit of the earth" * periodeia tēs chōrās, "circuit of the land" Apart from the "outline", two words recur, "earth" and "country." Something of a theorist, Strabo explains what he means by Geography and Chorography:It is the sea more than anything else that defines the contours of the land (''geōgraphei'') and g ...

Lighthouse
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 reef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stadion (unit)
The stadion (plural stadia, grc-gre, ; latinized as stadium), also anglicized as stade, was an ancient Greek unit of length, consisting of 600 Ancient Greek feet (''podes''). Calculations According to Herodotus, one stadium was equal to 600 Greek feet (''podes''). However, the length of the foot varied in different parts of the Greek world, and the length of the stadion has been the subject of argument and hypothesis for hundreds of years. An empirical determination of the length of the stadion was made by Lev Vasilevich Firsov, who compared 81 distances given by Eratosthenes and Strabo with the straight-line distances measured by modern methods, and averaged the results. He obtained a result of about . Various equivalent lengths have been proposed, and some have been named. Among them are: Which measure of the stadion is used can affect the interpretation of ancient texts. For example, the error in the calculation of Earth's circumference by Eratosthenes or Posidoniu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
