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 ...

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] |
History Of Alexandria
The history of Alexandria dates back to the city's founding, by Alexander the Great, in 331 BC. Yet, before that, there were some big port cities just east of Alexandria, at the western edge of what is now Abu Qir Bay. The Canopic (westernmost) branch of the Nile Delta still existed at that time, and was widely used for shipping. After its foundation, Alexandria became the seat of the Ptolemaic Kingdom, and quickly grew to be one of the greatest cities of the Hellenistic world. Only Rome, which gained control of Egypt in 30 BC, eclipsed Alexandria in size and wealth. The city fell to the Arabs in AD 641, and a new capital of Egypt, Fustat, was founded on the Nile. After Alexandria's status as the country's capital ended, it fell into a long decline, which by the late Ottoman period, had seen it reduced to little more than a small fishing village. The French army under Napoleon captured the city in 1798 and the British soon captured it from the French, retaining Alexandria ...

Lighthouse Of Alexandria
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 fl ...

Causeways
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way" making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, ''calx'', and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway utilised earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by enslaved bodies or flocks of sheep. Today, this work is done by machines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure Completed In The 3rd Century BC
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international community has created policy focused on sustai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3rd-century BC Establishments In Egypt
The 3rd century was the period from 201 ( CCI) to 300 ( CCC) Anno Domini (AD) or Common Era (CE) in the Julian calendar.. In this century, the Roman Empire saw a crisis, starting with the assassination of the Roman Emperor Severus Alexander in 235, plunging the empire into a period of economic troubles, barbarian incursions, political upheavals, civil wars, and the split of the Roman Empire through the Gallic Empire in the west and the Palmyrene Empire in the east, which all together threatened to destroy the Roman Empire in its entirety, but the reconquests of the seceded territories by Emperor Aurelian and the stabilization period under Emperor Diocletian due to the administrative strengthening of the empire caused an end to the crisis by 284. This crisis would also mark the beginning of Late Antiquity. In Persia, the Parthian Empire was succeeded by the Sassanid Empire in 224 after Ardashir I defeated and killed Artabanus V during the Battle of Hormozdgan. The Sassanids the ...

Ottomans
The Ottoman Turks ( tr, Osmanlı Türkleri), were the Turkic founding and sociopolitically the most dominant ethnic group of the Ottoman Empire ( 1299/1302–1922). Reliable information about the early history of Ottoman Turks remains scarce, but they take their Turkish name, ''Osmanlı'' ("Osman" became altered in some European languages as "Ottoman"), from the house of Osman I (reigned 1299–1326), the founder of the House of Osman, the ruling dynasty of the Ottoman Empire for its entire 624 years. Expanding from its base in Söğüt, the Ottoman principality began incorporating other Turkish-speaking Muslims and non-Turkish Christians. Crossing into Europe from the 1350s, coming to dominate the Mediterranean Sea and, in 1453, invading Constantinople (the capital city of the Byzantine Empire), the Ottoman Turks blocked all major land routes between Asia and Europe. Western Europeans had to find other ways to trade with the East. Brief history The "Ottomans" fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isthmus
An isthmus (; ; ) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Isthmus vs land bridge vs peninsula ''Isthmus'' and ''land bridge'' are related terms, with isthmus having a broader meaning. A land bridge is an isthmus connecting Earth's major landmasses. The term ''land bridge'' is usually used in biogeology to describe land connections that used to exist between continents at various times and were important for migration of people and various species of animals and plants, e.g. Beringia and Doggerland. An isthmus is a land connection between two bigger landmasses, while a peninsula is rather a land protrusion which is connected to a bigger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g. the Panama C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julius Caesar
Gaius Julius Caesar (; ; 12 July 100 BC – 15 March 44 BC), was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and subsequently became dictator from 49 BC until his assassination in 44 BC. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Crassus and Pompey formed the First Triumvirate, an informal political alliance that dominated Roman politics for several years. Their attempts to amass power as were opposed by the within the Roman Senate, among them Cato the Younger with the frequent support of Cicero.
