Basilica Cistern
The Basilica Cistern, or Cisterna Basilica ( el, βασιλική κινστέρνή, tr, Yerebatan Sarnıcı or tr, Yerebatan Saray, label=none, "Subterranean Cistern" or "Subterranean Palace"), is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul, Turkey. The cistern, located southwest of the Hagia Sophia on the historical peninsula of Sarayburnu, was built in the 6th century during the reign of Byzantine Emperor Justinian I. Today it is kept with little water, for public access inside the space. History This subterranean cistern was called Basilica because it was located under a large public square, the Stoa Basilica, on the First Hill of Constantinople. Prior to its construction, a great basilica stood on the spot. It had been built during the Early Roman Age between the 3rd and 4th centuries as a commercial, legal and artistic centre. The basilica was reconstructed by Illus after a fire in 476. Ancient texts indicated that the basil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Istanbul
Istanbul ( , ; tr, İstanbul ), formerly known as Constantinople ( grc-gre, Κωνσταντινούπολις; la, Constantinopolis), is the List of largest cities and towns in Turkey, largest city in Turkey, serving as the country's economic, cultural and historic hub. The city straddles the Bosporus strait, lying in both Europe and Asia, and has a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the list of European cities by population within city limits, most populous European city, and the world's List of largest cities, 15th-largest city. The city was founded as Byzantium ( grc-gre, Βυζάντιον, ) in the 7th century BCE by Ancient Greece, Greek settlers from Megara. In 330 CE, the Roman emperor Constantine the Great made it his imperial capital, renaming it first as New Rome ( grc-gre, Νέα Ῥώμη, ; la, Nova Roma) and then as Constantinople () after himself. The city grew in size and influence, eventually becom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahmed III
Ahmed III ( ota, احمد ثالث, ''Aḥmed-i sālis'') was Sultan of the Ottoman Empire and a son of Sultan Mehmed IV (r. 1648–1687). His mother was Gülnuş Sultan, originally named Evmania Voria, who was an ethnic Greek. He was born at Hacıoğlu Pazarcık, in Dobruja. He succeeded to the throne in 1703 on the abdication of his brother Mustafa II (1695–1703). Nevşehirli Damat İbrahim Pasha and the Sultan's daughter, Fatma Sultan (wife of the former) directed the government from 1718 to 1730, a period referred to as the ''Tulip Era''. The first days of Ahmed III's reign passed with efforts to appease the janissaries who were completely disciplined. However, he was not effective against the janissaries who made him sultan. Çorlulu Ali Pasha, who Ahmed brought to the Grand Vizier, tried to help him in administrative matters, made new arrangements for the treasury and Sultan. He supported Ahmed in his fight with his rivals. Early life and education Sultan Ahmed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valens Aqueduct
The Aqueduct of Valens ( tr, Valens Su Kemeri, grc, Ἀγωγὸς τοῦ ὕδατος, translit=Agōgós tou hýdatos, lit=aqueduct) was a Roman aqueduct system built in the late 4th century AD, to supply Constantinople – the capital of the eastern Roman empire. Construction of the aqueduct began during the reign of the Roman emperor Constantius II () and was completed in 373 by the emperor Valens (). The aqueduct remained in use for many centuries. It was extended and maintained by the Byzantines and the Ottomans. Initially, the Aqueduct of Valens carried water from springs at Danımandere and Pınarca; the channels from each spring met at Dağyenice. This 4th-century first phase of the system was long. A second, 5th-century phase added a further of conduits that took water from Vize, away from Constantinople. The final and most visible aqueduct bridge in the system survives in the Fatih district of Istanbul, Turkey. Named in , it is an important landmark in the cit ...

Belgrad Forest
Belgrad Forest ( tr, Belgrad Ormanı) is a mixed deciduous forest lying adjacent to Istanbul, Turkey. It is named after the village next to the forest, settled by thousands of Serbs who were deported to the capital Constantinople from the city of Belgrade in 1521, when it fell to the Ottomans. Geographically, the forest is located at the easternmost point of the Thracian Peninsula. Forest terrain is divided between Sarıyer and Eyüp districts. Several historical reservoirs lie within the forest. History The Thracian village of Belgrad (from which the forest takes its name) was named after the thousands of Serbs that Suleiman the Magnificent had transferred to Thrace after the 1521 Siege of Belgrade. Size and composition of the forest With a region around 5,500 hectares of forest it houses many plant, bird and animal species. The most common tree in the forest is sessile oak (''Quercus petraea''). Belgrad Forest is under protection and is one of the most visited recreational a ...

Firebrick
A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from wood, fluxing from ash or slag, and high temperatures. In other, less harsh situations, such as in an electric- or natural gas-fired kiln, more porous bricks, commonly known as "kiln bricks", are a better choice. They are weaker, but they are much lighter and easier to form and insulate far better than dense bricks. In any case, firebricks should not spall, and their strength should hold up well during rapid temperature changes. Manufacture In the making of firebrick, fireclay is fired in the kiln until ...

Spolia
''Spolia'' (Latin: 'spoils') is repurposed building stone for new construction or decorative sculpture reused in new monuments. It is the result of an ancient and widespread practice whereby stone that has been quarried, cut and used in a built structure is carried away to be used elsewhere. The practice is of particular interest to historians, archaeologists and architectural historians since the gravestones, monuments and architectural fragments of antiquity are frequently found embedded in structures built centuries or millennia later. The archaeologist Philip A. Barker gives the example of a late Roman period (probably 1st-century) tombstone from Wroxeter that could be seen to have been cut down and undergone weathering while it was in use as part of an exterior wall and, possibly as late as the 5th century, reinscribed for reuse as a tombstone. Overview The practice was common in late antiquity. Entire obsolete structures, including underground foundations, are known to h ...

Beyazıt Square
Beyazıt Square ( tr, Beyazıt Meydanı) lies to the north of Ordu Caddesi in the district of Fatih, Istanbul, Turkey. Officially named ''Freedom Square'' (), it is more generally known as Beyazıt Square after the early Ottoman Bayezid II Mosque on one side. The square is the former site of the Forum of Theodosius (AKA Forum Tauri) built by Constantine the Great. Its current form was designed by Turgut Cansever. Facing the mosque across the square is a medrese that formed part of its complex. In the past this served as a Museum of Calligraphy. After long years of closure, this was under restoration in 2022. On one side of the square is the main entrance to Istanbul University, its buildings designed by the French architect Marie-Auguste Antoine Bourgeois. It is accessible via a grand Neo-Renaissance arch. The Beyazıt Tower, once a fire-warning tower, in the grounds of the university is visible from the square. Between the entrance to the university and the mosque is the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forum Of Theodosius
The Forum of Theodosius ( el, φόρος Θεοδοσίου, today Beyazıt Square) was probably the largest square in Constantinople and stood on the Mese, the major road that ran west from Hagia Sophia (Turkish: Ayasofya). It was originally built by Constantine I, probably on the site of a pre-existing Hellenistic agora called the Strategion, and named the ''Forum Tauri'' ("Forum of the Bull"). In 393, however, it was renamed after Emperor Theodosius I, who rebuilt it after the model of Trajan's Forum in Rome, surrounded by civic buildings such as churches and baths and decorated with a triumphal column at its centre. Column of Theodosius Somewhere in the forum stood a Roman triumphal column erected in honour of emperor Theodosius I by his son Arcadius, who ruled as the Eastern Emperor after his father's death in A.D. 395. It probably stood in what is now the grounds of Istanbul University, on the north side of Beyazıt Square. Its shaft, decorated with relief sculpture ...

Doric Order
The Doric order was one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above. The Greek Doric column was fluted or smooth-surfaced, and had no base, dropping straight into the stylobate or platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Above a plain architrave, the complexity comes in the frieze, where the two features originally unique to the Doric, the triglyph and gutta, are skeuomorphic memories of the beams and retaining pegs of the wooden constructions that preceded sto ...

Corinthian Order
The Corinthian order ( Greek: Κορινθιακός ρυθμός, Latin: ''Ordo Corinthius'') is the last developed of the three principal classical orders of Ancient Greek architecture and Roman architecture. The other two are the Doric order which was the earliest, followed by the Ionic order. In Ancient Greek architecture, the Corinthian order follows the Ionic in almost all respects other than the capitals of the columns. When classical architecture was revived during the Renaissance, two more orders were added to the canon: the Tuscan order and the Composite order. The Corinthian, with its offshoot the Composite, is the most ornate of the orders. This architectural style is characterized by slender fluted columns and elaborate capitals decorated with acanthus leaves and scrolls. There are many variations. The name ''Corinthian'' is derived from the ancient Greek city of Corinth, although the style had its own model in Roman practice, following precedents set by ...

Ionic Order
The Ionic order is one of the three canonic orders of classical architecture, the other two being the Doric and the Corinthian. There are two lesser orders: the Tuscan (a plainer Doric), and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Corinthian order has the narrowest columns, followed by the Ionic order, with the Doric order having the widest columns. The Ionic capital is characterized by the use of volutes. The Ionic columns normally stand on a base which separates the shaft of the column from the stylobate or platform while the cap is usually enriched with egg-and-dart. The ancient architect and architectural historian Vitruvius associates the Ionic with feminine proportions (the Doric representing the masculine). Description Capital The major features of the Ionic order are the volutes of its capital, which have been the subject of much theoretical and practical discourse, based on a brief and obscure p ...
