Dolni Glavanak Cromlech
The Dolni Glavanak Cromlech is an oval stone circle located 2 kilometres west of village of Dolni Glavanak, some 12 kilometres from town of Madzharovo, in Bulgaria. The site is referred to as a cromlech by analogy with similar monuments in Western Europe, but it is the only structure of its kind known in the country. Description The site is situated on a low ridge-top above the left bank of the Arda river. It is enclosed on all sides and isolated from external influences. The circle consists of vertical, roughly-shaped, blocks of local hard volcanic rock (rhyodacite). The blocks are trapezoidal in shape, and are approximately 1.2 to 1.5 metres tall, and around 0.9 to 1.2 metres wide at the base, and 0.4 to 0.6 metres thick. Nine blocks still stand and three are now fallen. The vertical blocks are spaced at regular intervals, with smaller stones placed horizontally between them. The circle has an internal diameter of about 10 metres. There is an entrance on the southeast side. Ther ...

Dolmen
A dolmen () or portal tomb is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the early Neolithic (40003000 BCE) and were sometimes covered with earth or smaller stones to form a tumulus (burial mound). Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance.Murphy (1997), 43 In many instances, the covering has eroded away, leaving only the stone "skeleton". The Korean Peninsula is home to the world's highest concentration of dolmens,UNESCO World Heritage List. "Gochang, Hwasun and Ganghwa Dolmen Sites." https://whc.unesco.org/en/list/977 including "cemeteries" consisting of 30–100 examples located in close proximity to each other; with over 35,000 dolmens, Korea alone (for unknown reasons) accounts for approximately 40% of the global total. History It remains unclear when, why and by whom the earliest dolmens were mad ...

Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ...

Stone Circle
A stone circle is a ring of standing stones. Most are found in Northwestern Europe – especially in Britain, Ireland, and Brittany – and typically date from the Late Neolithic and Early Bronze Age, with most being built from 3000 BC. The best known examples include those at the henge monument at Avebury, the Rollright Stones, and elements within the ring of standing stones at Stonehenge. Scattered examples exist from other parts of Europe. Later, during the Iron Age, stone circles were built in southern Scandinavia. Stone circles are usually grouped in terms of the shape and size of the stones, the span of their radius, and their population within the local area. Although many theories have been advanced to explain their use, usually related to providing a setting for ceremony or ritual, no consensus exists among archaeologists regarding their intended function. Their construction often involved considerable communal effort, including specialist tasks such as planning, quar ...

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Rhyodacite
Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. It is the extrusive equivalent of those plutonic rocks that are intermediate in composition between monzogranite and granodiorite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides. Description Under IUGS guidelines, rhyodacites are not formally defined in either the QAPF classification, used to classify igneous rocks by their mineral content, or the TAS classification, used to classify volcanic rocks chemically. However, the IUGS allows the use of the term to describe rocks close to the boundary between the rhyolite and dacite fields in each classification scheme. Rhyodacite then describes a fine-grained igneous rock containing between 20% and 60% quartz and in which plagioclase makes up about two-thirds of the total feldspar content. Such a rock will contain between 69% and 72% silica by weight. The U.S. Geological Survey defines rhyodacite ...

Archaeological Sites In Bulgaria
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of ...

Megalithic Monuments In Europe
A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 in Europe alone, located widely from Sweden to the Mediterranean sea. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "mega" for great and "lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic period and into the Bronze Age. At that time, the beliefs that developed were dynamism and animism, because Indonesia experienced the megalithic age or the great stone age in 2100 to 4000 BC. So that humans ancient tribe worship certain objects that are considered to have supernatural powers. Some relics of the megalithic era are menhirs (stone monuments) and dolmens (stone tables). Types and definitions While "megalith" is o ...

History Of Haskovo Province
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
