Traiectum (Utrecht)
Traiectum was a Roman fort, on the frontier of the Roman Empire in Germania Inferior. The remains of the fort are in the center of Utrecht, Netherlands, which takes its name from the fort. History In the Roman Empire Traiectum was one of the forts in the lower Limes Germanicus defensive lines. The Emperor Claudius defined the Rhine downstream from Bonn as the western part of the frontier. He ordered the legions further north to withdraw to this line, which was fortified in AD 47. The Rhine divides into several branches in the Netherlands. The army chose the branch on which modern Utrecht lies as the frontier. In AD 69-70 Gaius Julius Civilis led the revolt of the Batavi during which the fort was burned. One soldier or officer buried his savings of fifty gold coins at this time. They were found by archaeologists below the layer of burned wood. Once the Romans had restored their authority in the region they rebuilt the fort, again in wood. The fort was manned by about ...

Limes Germanicus
The (Latin for ''Germanic frontier'') is the name given in modern times to a line of frontier () fortifications that bounded the ancient Roman provinces of Germania Inferior, Germania Superior and Raetia, dividing the Roman Empire and the unsubdued Germanic tribes from the years 83 to about 260 AD. The Limes used either a natural boundary such as a river or typically an earth bank and ditch with a wooden palisade and watchtowers at intervals. A system of linked forts was built behind the Limes. The path of the limes changed over time following advances and retreats due to pressure from external threats. At its height, the Limes Germanicus stretched from the North Sea outlet of the Rhine to near Regensburg ( Castra Regina) on the Danube. These two major rivers afforded natural protection from mass incursions into imperial territory, with the exception of a gap stretching roughly from (Mainz) on the Rhine to Castra Regina. The Limes Germanicus was divided into: *The Lower Germ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Roman Army
The Imperial Roman army was the military land force of the Roman Empire from about 30 BC to 476 AD, and the final incarnation in the long history of the Roman army. This period is sometimes split into the Principate (30 BC – 284 AD) and the Dominate (285–476) periods. Under Augustus (), the army consisted of '' legions'', eventually ''auxilia'' and also '' numeri''. By the end of Augustus' reign, the imperial army numbered some 250,000 men, equally split between 25 legions and 250 units of auxiliaries. The numbers grew to a peak of about 450,000 by 211, in 33 legions and about 400 auxiliary units. By then, auxiliaries outnumbered legionaries substantially. From this peak, numbers probably underwent a steep decline by 270 due to plague and losses during multiple major barbarian invasions. Numbers were restored to their early 2nd-century level of c. 400,000 (but probably not to their 211 peak) under Diocletian (r. 284–305). After the Empire's borders became settled (on the R ...

Duitse Huis
The ''Duitse Huis'' ( en, Teutonic House) is a complex of buildings in the city of Utrecht, Netherlands, protected as a national monument. The older parts date to a monastery of the Bailiwick of Utrecht of the Teutonic Knights founded in 1348. Originally Catholic, the order became Protestant during the Reformation. A military hospital was added in 1823 after the knights had sold the property. The property was sold back to the Bailiwick of Utrecht and a major renovation started in 1992. Some of the older buildings are again the headquarters of the Bailiwick of Utrecht, now a charity, and hold an important collection of medieval manuscripts, coins and pictures. Other buildings, including the former hospital, have been converted into a five-star hotel, the Grand Hotel Karel V. Teutonic Order The Teutonic Order was one of the great Christian military orders, along with the Knights Templar and Knights Hospitaller. It was mainly active in the Holy Land and the Baltic region, but h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vicus
In Ancient Rome, the Latin term (plural ) designated a village within a rural area () or the neighbourhood of a larger settlement. During the Republican era, the four of the city of Rome were subdivided into . In the 1st century BC, Augustus reorganized the city for administrative purposes into 14 regions, comprising 265 . Each had its own board of officials who oversaw local matters. These administrative divisions are recorded as still in effect at least until the mid-4th century. The word "" was also applied to the smallest administrative unit of a provincial town within the Roman Empire. It is also notably used today to refer to an ''ad hoc'' provincial civilian settlement that sprang up close to and because of a nearby military fort or state-owned mining operation. Local government in Rome Each ''vicus'' elected four local magistrates ('' vicomagistri'') who commanded a sort of local police force chosen from among the people of the ''vicus'' by lot.

Ditch (fortification)
In military engineering, a ditch is an obstacle designed to slow down or break up an attacking force, while a trench is intended to provide cover to the defenders. In military fortifications the side of a ditch farthest from the enemy and closest to the next line of defence is known as the scarp while the side of a ditch closest to the enemy is known as the counterscarp. Uses In early fortifications, ditches were often used in combination with ramparts to slow down the enemy whilst defensive fire could be brought to bear from the relative protection afforded by the rampart and possibly the palisade. In medieval fortification, a ditch was often constructed in front of a defensive wall to hinder mining and escalade activities from an attacker. When filled with water, such a defensive ditch is called a moat. However, moats may also be dry. Later star forts designed by military engineers like Vauban, comprised elaborate networks of ditches and parapets, carefully calculated ...

Sacellum
In ancient Roman religion, a ''sacellum'' is a small shrine. The word is a diminutive from ''sacrum'' (neuter of ''sacer'', "belonging to a god"). The numerous ''sacella'' of ancient Rome included both shrines maintained on private properties by families, and public shrines. A ''sacellum'' might be square or round. Varro and Verrius Flaccus describe ''sacella'' in ways that at first seem contradictory, the former defining a ''sacellum'' in its entirety as equivalent to a ''cella'', which is specifically an enclosed space, and the latter insisting that a ''sacellum'' had no roof. "Enclosure," however, is the shared characteristic, roofed over or not. "The ''sacellum''," notes Jörg Rüpke, "was both less complex and less elaborately defined than a temple proper." The meaning can overlap with that of ''sacrarium'', a place where sacred objects ''(sacra)'' were stored or deposited for safekeeping. The ''sacella'' of the Argei, for instance, are also called ''sacraria''. In private ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underfloor Heating
Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods. History Underfloor heating has a long history back into the Neoglacial and Neolithic periods. Archeological digs in Asia and the Aleutian islands of Alaska reveal how the inhabitants drafted smoke from fires through stone covered trenches which were excavated in the floors of their subterranean dwellings. The hot smoke heated the floor stones and the heat then radiated into the living spaces. These early forms have evolved into modern systems using fluid filled pipes or electrical cables and mats. Below is a chronological overview of under floor heating from around the world. Description Modern underfloor heating systems use either electrical r ...

Hypocaust
A hypocaust ( la, hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes. This air can warm the upper floors as well. The word derives from the Ancient Greek meaning "under" and , meaning "burnt" (as in ''caustic''). The earliest reference to such a system suggests that the temple of Ephesus in 350 BC was heated in this manner, although Vitruvius attributes its invention to Sergius Orata in c. 80 BC. Its invention improved the hygiene and living conditions of citizens, and was a forerunner of modern central heating. Roman operation Hypocausts were used for heating hot baths and other public buildings in Ancient Rome. They were also used in private homes. It was a must for the villas of the wealthier merchant class throughout the Roman Empire. The ruins of Roman hypocausts have been found throughout Europe (for example in Ital ...

Portico
A portico is a porch leading to the entrance of a building, or extended as a colonnade, with a roof structure over a walkway, supported by columns or enclosed by walls. This idea was widely used in ancient Greece and has influenced many cultures, including most Western cultures. Some noteworthy examples of porticos are the East Portico of the United States Capitol, the portico adorning the Pantheon in Rome and the portico of University College London. Porticos are sometimes topped with pediments. Palladio was a pioneer of using temple-fronts for secular buildings. In the UK, the temple-front applied to The Vyne, Hampshire, was the first portico applied to an English country house. A pronaos ( or ) is the inner area of the portico of a Greek or Roman temple, situated between the portico's colonnade or walls and the entrance to the ''cella'', or shrine. Roman temples commonly had an open pronaos, usually with only columns and no walls, and the pronaos could be as long as th ...

Bastion
A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort. The fully developed bastion consists of two faces and two flanks, with fire from the flanks being able to protect the curtain wall and the adjacent bastions. Compared with the medieval fortified towers they replaced, bastion fortifications offered a greater degree of passive resistance and more scope for ranged defence in the age of gunpowder artillery. As military architecture, the bastion is one element in the style of fortification dominant from the mid 16th to mid 19th centuries. Evolution By the middle of the 15th century, artillery pieces had become powerful enough to make the traditional medieval round tower and curtain wall obsolete. This was exemplified by the campaigns of Charles VII of France who reduced the towns and castles held by the English during the latter stages of the Hundred Years War, ...

Gate Tower
A gate tower (german: Torturm) is a tower built over or next to a major gateway. Usually it is part of a medieval fortification. This may be a town or city wall, fortress, castle or castle chapel. The gate tower may be built as a twin tower on either side of an entranceway. Even in the design of modern building complexes, gate towers may be constructed symbolically as a main entrance. The gate tower can also stand as a twin tower on both sides of a gate system. Gate towers are also used symbolically as the main entrance in the design of modern building complexes. The Kasselburg in Rhineland-Palatinate has a double tower gate tower, which was also used as a residential tower.
