Ceiling Tile
A ceiling is an overhead interior roof that covers the upper limits of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the roof structure or the floor of a story above. Ceilings can be decorated to taste, and there are many examples of frescoes and artwork on ceilings, especially within religious buildings. A ceiling can also be the upper limit of a tunnel. The most common type of ceiling is the dropped ceiling, which is suspended from structural elements above. Panels of drywall are fastened either directly to the ceiling joists or to a few layers of moisture-proof plywood which are then attached to the joists. Pipework or ducts can be run in the gap above the ceiling, and insulation and fireproofing material can be placed here. Alternatively, ceilings may be spray painted instead, leaving the pipework and ducts exposed but painted, and using spray foam. A subset of the dropped ceiling is the suspended ceiling, w ...

Roof
A roof (: roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice, and may also be governed by local or national legislation. In most countries, a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a Conservatory (greenhouse), garden conservatory protects plants from cold, wind, and rain, but admits light. A roof may also provide additional living space, for example, a roof garden. Etymology Old English 'roof, ceiling, top, summ ...

Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Rome, Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean civilisation, Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics.

Raymond Bidollet
Raymond is a male given name of Germanic origin. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' ( Gothic) and ''regin'' (Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded ...

Louvre Palace
The Louvre Palace (, ), often referred to simply as the Louvre, is an iconic French palace located on the Right Bank of the Seine in Paris, occupying a vast expanse of land between the Tuileries Gardens and the church of Saint-Germain l'Auxerrois. Originally a defensive castle, it has served several government-related functions in the past, including intermittently as a royal residence between the 14th and 18th centuries. It is now mostly used by the Louvre Museum, which first opened there in 1793. While this area along the Seine had been inhabited for thousands of years, the Louvre's history starts around 1190 with its first construction as the Louvre Castle defending the western front of the Wall of Philip II Augustus, the then new city-wall of Paris. The Louvre's oldest section still standing above ground, its palatial Lescot Wing, dates from the late 1540s, when Francis I started the replacement of the greatly expanded medieval castle with a new design inspired by cla ...

Renaissance Architecture
Renaissance architecture is the European architecture of the period between the early 15th and early 16th centuries in different regions, demonstrating a conscious revival and development of certain elements of Ancient Greece, ancient Greek and Ancient Rome, Roman thought and material culture. Stylistically, Renaissance architecture followed Gothic architecture and was succeeded by Baroque architecture and neoclassical architecture. Developed first in Florence, with Filippo Brunelleschi as one of its innovators, the Renaissance style quickly spread to other Italian cities. The style was carried to other parts of Europe at different dates and with varying degrees of impact. It began in Florence in the early 15th century and reflected a revival of classical Greek and Roman principles such as symmetry, proportion, and geometry. This movement was supported by wealthy patrons, including the Medici family and the Catholic Church, who commissioned works to display both religious devot ...

Pierre De Montreuil
Pierre de Montreuil (; died 17 March 1267) was a French architect. The name formerly given to him by architectural historians, Peter of Montereau (in French, Pierre de Montereau), is a misnomer. It was based on his tombstone inscription ''Musterolo natus'' ("born in Musterolo"), a place name that was mistakenly identified as Montereau rather than Montreuil. Documented work He is one of the first named architects of 13th-century Paris, and, according to Anne Prache (writing in ''The Dictionary of Art''), "there has been a tendency to attribute an immense role to him."Prache 1996. Only the refectory (1239–1244, destroyed) and chapel of the Virgin (1245–, only fragments remain) of the former abbey of Saint-Germain-des-Prés can be definitely said to be by him. He is thought to have been a master at the Basilique Saint-Denis beginning around 1247, although his specific contributions are unknown, and it is also generally agreed that he completed the south transept of Notre-Dam ...

Sainte-Chapelle
The Sainte-Chapelle (; ) is a royal chapel in the Gothic style, within the medieval Palais de la Cité, the residence of the Kings of France until the 14th century, on the Île de la Cité in the River Seine in Paris, France. Construction began sometime after 1238 and the chapel was consecrated on 26 April 1248. The Sainte-Chapelle is considered among the highest achievements of the Rayonnant period of Gothic architecture. It was commissioned by King Louis IX of France to house his collection of Passion relics, including Christ's claimed Crown of Thorns – one of the most important relics in medieval Christendom. This was later held in the nearby Notre-Dame Cathedral until the 2019 fire, which it survived. Along with the Conciergerie, Sainte-Chapelle is one of the earliest surviving buildings of the Capetian royal palace on the Île de la Cité. Although damaged during the French Revolution and restored in the 19th century, it has one of the most extensive 13th- ...

Gothic Architecture
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High Middle Ages, High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the Classical architecture, architecture of classical antiquity. The defining design element of Gothic architecture is the Pointed arch (architecture), pointed arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Basilica of Saint-Denis, Saint-Denis, near Paris, the choir was rec ...

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ...

System
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its open system (systems theory), environment, is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek language, Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα"
