Polygonal masonry is a technique of stone wall construction. True polygonal masonry is a technique wherein the visible surfaces of the stones are dressed with straight sides or joints, giving the block the appearance of a polygon. [1]
This technique is found throughout the world and sometimes corresponds to the less technical category of Cyclopean masonry. [2]
And others
In Italy, polygonal masonry is particularly indicative of the region of Latium, but it occurs also in Etruria, Lucania, Samnium, and Umbria; scholars including Giuseppe Lugli have carried out studies of the technique. [3] [4] Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina, and Terracina. [5] The Porta Rosa of the ancient city of Velia employs a variant of the technique known as Lesbian masonry. [1]
Romanesque architecture is an architectural style of medieval Europe that was predominant in the 11th and 12th centuries. The style eventually developed into the Gothic style with the shape of the arches providing a simple distinction: the Romanesque is characterized by semicircular arches, while the Gothic is marked by the pointed arches. The Romanesque emerged nearly simultaneously in multiple countries ; its examples can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. Similarly to Gothic, the name of the style was transferred onto the contemporary Romanesque art.
A fortification is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere.
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.
Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire, usually dated from 330 AD, when Constantine the Great established a new Roman capital in Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. There was initially no hard line between the Byzantine and Roman Empires, and early Byzantine architecture is stylistically and structurally indistinguishable from late Roman architecture. The style continued to be based on arches, vaults and domes, often on a large scale. Wall mosaics with gold backgrounds became standard for the grandest buildings, with frescos a cheaper alternative.
Anglo-Saxon architecture was a period in the history of architecture in England from the mid-5th century until the Norman Conquest of 1066. Anglo-Saxon secular buildings in Britain were generally simple, constructed mainly using timber with thatch for roofing. No universally accepted example survives above ground. Generally preferring not to settle within the old Roman cities, the Anglo-Saxons built small towns near their centres of agriculture, at fords in rivers or sited to serve as ports. In each town, a main hall was in the centre, provided with a central hearth.
Drobeta-Turnu Severin, colloquially Severin, is a city in Mehedinți County, Oltenia, Romania, on the northern bank of the Danube, close to the Iron Gates. "Drobeta" is the name of the ancient Dacian and Roman towns at the site, and the modern town of Turnu Severin received the additional name of Drobeta during Nicolae Ceaușescu's national-communist dictatorship as part of his myth-making efforts.
A barrel vault, also known as a tunnel vault, wagon vault or wagonhead vault, is an architectural element formed by the extrusion of a single curve along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault: effectively a series of arches placed side by side. It is a form of barrel roof.
Cyclopean masonry is a type of stonework found in Mycenaean architecture, built with massive limestone boulders, roughly fitted together with minimal clearance between adjacent stones and with clay mortar or no use of mortar. The boulders typically seem unworked, but some may have been worked roughly with a hammer and the gaps between boulders filled in with smaller chunks of limestone.
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 simpler lines, showing great regional diversity and often demonstrating local vernacular technology and decoration.
Portuguese architecture refers to both the architecture of Portugal's modern-day territory in Continental Portugal, the Azores and Madeira, as well as the architectural heritage/patrimony of Portuguese architects and styles throughout the world, particularly in countries formerly part of the Portuguese Empire.
Armenian architecture comprises architectural works with an aesthetic or historical connection to the Armenian people. It is difficult to situate this architectural style within precise geographical or chronological limits, but many of its monuments were created in the regions of historical Armenia, the Armenian Highlands. The greatest achievement of Armenian architecture is generally agreed to be its medieval churches and seventh century churches, though there are different opinions precisely in which respects.
The Architecture of the Tarnovo Artistic School is a term for the development of architecture during the Second Bulgarian Empire (1185–1396). In the 13th and 14th centuries the capital Tarnovo determined the progress of the Bulgarian architecture with many edifices preserved or reconstructed which show the skills of the Medieval Bulgarian architects and the construction and decorative techniques they used. The builders have created a unique architectural style, known as Tarnovian Style, that influenced the architecture in many countries of Southeastern Europe and parts of Central Europe. With its diverse architecture, the Tarnovo School may be separated into several branches according to the function of the buildings.
The architecture of Provence includes a rich collection of monuments from the Roman era, Cistercian monasteries from the Romanesque period, medieval castles and fortifications, as well as numerous hilltop villages and fine churches. Provence was a very poor region after the 18th century, but in the 20th century it had an economic revival and became the site of one of the most influential buildings of the 20th century, the Unité d'Habitation of the architect Le Corbusier in Marseille.
Defensive walls are a feature of ancient Roman architecture. The Romans generally fortified cities, rather than building stand-alone fortresses, but there are some fortified camps, such as the Saxon Shore forts like Porchester Castle in England. City walls were already significant in Etruscan architecture, and in the struggle for control of Italy under the early Republic many more were built, using different techniques. These included tightly fitting massive irregular polygonal blocks, shaped to fit exactly in a way reminiscent of later Inca work. The Romans called a simple rampart wall an agger; at this date great height was not necessary. The Servian Wall around Rome was an ambitious project of the early 4th century BC. The wall was up to 10 metres (32.8 ft) in height in places, 3.6 metres (12 ft) wide at its base, 11 km (7 mi) long, and is believed to have had 16 main gates, though many of these are mentioned only from writings, with no other known remains. Some of it had a fossa or ditch in front, and an agger behind, and it was enough to deter Hannibal. Later the Aurelian Wall replaced it, enclosing an expanded city, and using more sophisticated designs, with small forts at intervals.
The Church of Saint Simeon Stylites is one of the oldest surviving church complexes, founded in the 5th century. It is located approximately 30 kilometres (19 mi) northwestern of Aleppo, Syria. It was constructed on the site of the pillar of Saint Simeon Stylites, a renowned stylite monk. The church is popularly known as either Qalaat Semaan or Deir Semaan.
Cefalù, classically known as Cephaloedium, is a city and comune in the Italian Metropolitan City of Palermo, located on the Tyrrhenian coast of Sicily about 70 km (43 mi) east of the provincial capital and 185 km (115 mi) west of Messina. The town, with its population of just under 14,000, is one of the major tourist attractions in the region. Despite its size, every year it attracts millions of tourists from all parts of Sicily, and also from all over Italy and Europe. It is one of I Borghi più belli d'Italia.
The architecture of Scotland in the Middle Ages includes all building within the modern borders of Scotland, between the departure of the Romans from Northern Britain in the early fifth century and the adoption of the Renaissance in the early sixteenth century, and includes vernacular, ecclesiastical, royal, aristocratic and military constructions. The first surviving houses in Scotland go back 9500 years. There is evidence of different forms of stone and wooden houses exist and earthwork hill forts from the Iron Age. The arrival of the Romans led to the abandonment of many of these forts. After the departure of the Romans in the fifth century, there is evidence of the building of a series of smaller "nucleated" constructions sometimes utilizing major geographical features, as at Dunadd and Dumbarton. In the following centuries new forms of construction emerged throughout Scotland that would come to define the landscape.
Domes were a characteristic element of the architecture of Ancient Rome and of its medieval continuation, the Byzantine Empire. They had widespread influence on contemporary and later styles, from Russian and Ottoman architecture to the Italian Renaissance and modern revivals. The domes were customarily hemispherical, although octagonal and segmented shapes are also known, and they developed in form, use, and structure over the centuries. Early examples rested directly on the rotunda walls of round rooms and featured a central oculus for ventilation and light. Pendentives became common in the Byzantine period, provided support for domes over square spaces.
The architecture of Albania is a reflection of Albania's historical and cultural heritage. The country's architecture was influenced by its location within the Mediterranean Basin and progressed over the course of history as it was once inhabited by numerous civilisations including the Illyrians, Ancient Greeks, Romans, Byzantines, Venetians, Ottomans as well as modern Austro-Hungarians and Italians. In addition, missionaries, invaders, colonisers and traders brought cultural changes that had a large profound effect on building styles as well as techniques.
