Monolithic Architecture
Monolithic architecture describes buildings which are carved, cast or excavated from a single piece of material, historically from rock. The most basic form of monolithic architecture is a rock-cut building, such as the monolithic churches of Ethiopia built by the Zagwe dynasty, or the Pancha Rathas in India. These are cut out of solid rock, to which they remain attached at the base. In most cases this is evident from the remaining surrounding rock, but sometimes a building is cut from an outcrop, as in the Shore Temple in southern India, and only inspection at close quarters reveals that the building is monolithic. The terms ''monolith'' and '' monolithic column'' are normally used for objects made from a single large piece of rock which is detached from the ground. They may have been moved a considerable distance, as with several ancient Egyptian obelisks, which have been moved around the world. Buildings with a structural material that is poured into place, most commonly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Christian Art And Architecture
Early Christian art and architecture or Paleochristian art is the art produced by Christians or under Christian patronage from the earliest period of Christianity to, depending on the definition used, sometime between 260 and 525. In practice, identifiably Christian art only survives from the 2nd century onwards. After 550 at the latest, Christian art is classified as Byzantine, or of some other regional type. It is hard to know when distinctly Christian art began. Prior to 100, Christians may have been constrained by their position as a persecuted group from producing durable works of art. Since Christianity was largely a religion not well represented in the public sphere, the lack of surviving art may reflect a lack of funds for patronage, and simply small numbers of followers. The Old Testament restrictions against the production of graven (an idol or fetish carved in wood or stone) images (see also Idolatry and Christianity) may also have constrained Christians from producing ...

Church Architecture
Church architecture refers to the architecture of buildings of churches, convents, seminaries etc. It has evolved over the two thousand years of the Christian religion, partly by innovation and partly by borrowing other architectural styles as well as responding to changing beliefs, practices and local traditions. From the birth of Christianity to the present, the most significant objects of transformation for Christian architecture and design were the great churches of Byzantium, the Romanesque abbey churches, Gothic cathedrals and Renaissance basilicas with its emphasis on harmony. These large, often ornate and architecturally prestigious buildings were dominant features of the towns and countryside in which they stood. However, far more numerous were the parish churches in Christendom, the focus of Christian devotion in every town and village. While a few are counted as sublime works of architecture to equal the great cathedrals and churches, the majority developed along si ...

Architecture Of Cathedrals And Great Churches
The architecture of cathedrals and great churches is characterised by the buildings' large scale and follows one of several branching traditions of form, function and style that derive ultimately from the Early Christian architectural traditions established in Late Antiquity during the Christianization of the Roman Empire. Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

Ravenna
Ravenna ( , , also ; rgn, Ravèna) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire from 408 until its collapse in 476. It then served as the capital of the Ostrogothic Kingdom until it was re-conquered in 540 by the Byzantine Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the last exarch was executed by the Lombards in 751. Although it is an inland city, Ravenna is connected to the Adriatic Sea by the Candiano Canal. It is known for its well-preserved late Roman and Byzantine architecture, with eight buildings comprising the UNESCO World Heritage Site "Early Christian Monuments of Ravenna". History The origin of the name ''Ravenna'' is unclear. Some have speculated that "Ravenna" is related to "Rasenna" (or "Rasna"), the term that the Etruscan civilization, Etruscans used for themselves, but there is no agreement on this point. Ancien ...

Mausoleum Of Theodoric
The Mausoleum of Theodoric ( it, Mausoleo di Teodorico) is an ancient monument just outside Ravenna, Italy. It was built in 520 AD by Theodoric the Great, king of the Ostrogoths, as his future tomb. Description The mausoleum's current structure consists of two decagonal orders, one above the other made of Istrian stone, sourced from a quarry approximately away by land journey. The mausoleum's roof consists of a single carved stone in diameter weighing 230 tonnes. A niche leads down to a room that was probably a chapel for funeral liturgies; an external stair leads to the upper floor. Located in the centre of the upper floor is a fragmentary ancient Roman porphyry tub, likely from a bath complex, in which Theodoric was buried. His remains were removed during Byzantine rule, when the mausoleum was turned into a Christian oratory. In the late 19th century, silting from a nearby rivulet that had partly submerged the mausoleum was drained and excavated. Recognition It was inscrib ...

Formwork
Formwork is Molding (process), molds into which concrete or similar materials are either precast concrete, precast or cast-in-place concrete, cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure. Types Formwork may be made of wood, metal, plastic, or composite materials: #''Traditional timber formwork''. The formwork is built on site out of timber and plywood or moisture-resistant particleboard. It is easy to produce but time-consuming for larger structures, and the plywood facing has a relatively short lifespan. It is still used extensively where the labour costs are lower than the costs for procuring reusable formwork. It is also the most flexible type of formwork, so even where other systems are in use, complicated sections may use it. #''Engineered Formwork System''. Th ...

Monolithic Dome
A monolithic dome (from Greek mono- and -lithic, meaning "one stone") is a thin-shell structure cast in a one-piece form. The form may be permanent or temporary and may or may not remain part of the finished structure. Monolithic domes are a form of monolithic architecture. History The igloo may be the earliest form of monolithic dome. While it is constructed of blocks of compressed snow, these blocks melt and re-freeze to form a strong, homogeneous structure. The dome-like shape of the igloo exhibits the two major advantages of a dome-shaped structure: great strength, and good insulation. The strength is due to the natural strength of the arch, and the insulation is due to the minimal surface area of a spherical section. The first modern monolithic dome structure was built in Provo, Utah, by architect Lee C. Knell, and opened in 1963 as an ice skating rink. Called ''Turtle Reams'' after its 1967 conversion into a general store by new owner Paul Ream, the building st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Obelisk
An obelisk (; from grc, ὀβελίσκος ; diminutive of ''obelos'', " spit, nail, pointed pillar") is a tall, four-sided, narrow tapering monument which ends in a pyramid-like shape or pyramidion at the top. Originally constructed by Ancient Egyptians and called ''tekhenu'', the Greeks used the Greek term to describe them, and this word passed into Latin and ultimately English. Ancient obelisks are monolithic; they consist of a single stone. Most modern obelisks are made of several stones. Ancient obelisks Egyptian Obelisks were prominent in the architecture of the ancient Egyptians, and played a vital role in their religion placing them in pairs at the entrance of the temples. The word "obelisk" as used in English today is of Greek rather than Egyptian origin because Herodotus, the Greek traveler, was one of the first classical writers to describe the objects. A number of ancient Egyptian obelisks are known to have survived, plus the " Unfinished Obelisk" found part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monolith
A monolith is a geological feature consisting of a single massive rock (geology), stone or rock, such as some mountains. For instance, Savandurga, Savandurga mountain is a monolith mountain in India. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous rock, igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano. In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces. The word derives, via the Latin , from the Ancient Greek word (), from () meaning "one" or "sing ...
