List Of Roman Domes
This is a list of Roman domes. The Romans were the first builders in the history of architecture to realize the potential of domes for the creation of large and well-defined interior spaces. Domes were introduced in a number of Roman building types such as temples, thermae, palaces, mausolea and later also churches. Semi-domes also became a favoured architectural element and were adopted as apses in Christian church architecture. Monumental domes began to appear in the 1st century BC in Rome and the provinces around the Mediterranean Sea. Along with vaults and trusses, they gradually replaced the traditional post and lintel construction which makes use of the column and architrave. The construction of domes was greatly facilitated by the invention of concrete, a process which has been termed the Roman Architectural Revolution. Their enormous dimensions remained unsurpassed until the introduction of structural steel frames in the late 19th century (see List of largest domes). ...

Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed. Vault types Corbelled vaults, also called false vaults, with horizontally joined layers of stone have been documented since prehistoric times; in the 14th century BC from Mycenae. They were built regionally until modern times. The real vault construction with radially joined stones was already known to the Egyptians and Assyrians and was introduced into the buil ...

List Of World's Largest Domes
A dome is a self-supporting structural element of architecture that resembles the hollow upper half of a sphere. Every dome in the world which was the largest dome of its time is listed below. The defining criterion is in each case the inner diameter of the largest circular cross-section of the dome. This list excludes dome-shaped structures that are not self-supporting such as The O2 in London which is in diameter and supported by masts. Worldwide Below is a list of buildings that have held the title of the largest dome in the world.

Opus Caementicium
Roman concrete, also called , is a material that was used in construction in ancient Rome. Roman concrete was based on a hydraulic-setting cement. It is durable due to its incorporation of pozzolanic ash, which prevents cracks from spreading. By the middle of the 1st century the material was used frequently, often brick-faced, although variations in aggregate allowed different arrangements of materials. Further innovative developments in the material, called the concrete revolution, contributed to structurally complicated forms, such as the Pantheon dome, the world's largest and oldest unreinforced concrete dome. Roman concrete was normally faced with stone or brick, and interiors might be further decorated by stucco, fresco paintings, or thin slabs of fancy colored marbles. Made up of aggregate and a two-part cementitious system it differs significantly from modern concrete. The aggregates were typically far larger than in modern concrete as well, often amounting to rubble, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotunda (architecture)
A rotunda () is any building with a circular ground plan, and sometimes covered by a dome. It may also refer to a round room within a building (a famous example being the one below the dome of the United States Capitol in Washington, D.C.). The Pantheon in Rome is a famous rotunda. A ''band rotunda'' is a circular bandstand, usually with a dome. Rotunda in Central Europe A great number of parochial churches were built in this form in the 9th to 11th centuries CE in Central Europe. These round churches can be found in great number in Hungary, Poland, Slovakia, Croatia (particularly Dalmatia) Austria, Bavaria, Germany, and the Czech Republic. It was thought of as a structure descending from the Roman Pantheon. However, it can be found mainly not on former Roman territories, but in Central Europe. Generally its size was 6–9 meters inner diameter and the apse was directed toward the east. Sometimes three or four apses were attached to the central circle and this type has relatives ...

Pantheon, Rome
The Pantheon (, ; la, Pantheum,Although the spelling ''Pantheon'' is standard in English, only ''Pantheum'' is found in classical Latin; see, for example, Pliny, '' Natural History'36.38 "Agrippas Pantheum decoravit Diogenes Atheniensis". See also ''Oxford Latin Dictionary'', s.v. "Pantheum"; ''Oxford English Dictionary'', s.v"Pantheon" "post-classical Latin ''pantheon'' a temple consecrated to all the gods (6th cent.; compare classical Latin ''pantheum'')". from Greek ''Pantheion'', " empleof all the gods") is a former Roman temple and, since 609 AD, a Catholic church (Basilica di Santa Maria ad Martyres or Basilica of St. Mary and the Martyrs) in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). It was rebuilt by the emperor Hadrian and probably dedicated 126 AD. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain the i ...

Oculus (architecture)
An oculus (; ) is a circular opening in the center of a dome or in a wall. Originating in antiquity, it is a feature of Byzantine and Neoclassical architecture. It is also known as an '' œil-de-boeuf'' from the French, or simply a "bull's-eye". History Classical The oculus was used by the Ancient Romans, one of the finest examples being that in the dome of the Pantheon. Open to the weather, it allows rain and air to enter and fall to the floor, where it is carried away through drains. Though the opening looks small, it actually has a diameter of , allowing it to light the building. Byzantine The oculus was widely used in the architecture of the Byzantine Empire. It was applied to buildings in Syria in the 5th and 6th centuries and again in the 10th century. In Constantinople's Myrelaion Church (c. 920), there are two oculi above the stringcourse on both lateral facades. Renaissance Early examples of the oculus in Renaissance architecture can be seen in Florence Cathedral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Architrave
In classical architecture, an architrave (; from it, architrave "chief beam", also called an epistyle; from Greek ἐπίστυλον ''epistylon'' "door frame") is the lintel or beam that rests on the capitals of columns. The term can also apply to all sides, including the vertical members, of a frame with mouldings around a door or window. The word "architrave" has come to be used to refer more generally to a style of mouldings (or other elements) framing a door, window or other rectangular opening, where the horizontal "head" casing extends across the tops of the vertical side casings where the elements join (forming a butt joint, as opposed to a miter joint). Classical architecture In an entablature in classical architecture, it is the lowest part, below the frieze and cornice. The word is derived from the Greek and Latin words ''arche'' and ''trabs'' combined to mean "main beam". The architrave is different in the different Classical orders. In the Tuscan o ...
