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 Late Neolithic period and were sometimes covered with earth or smaller stones to form a tumulus. Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance. In many instances, the covering has eroded away, leaving only the stone "skeleton".
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.
Carrowmore is a large group of megalithic monuments on the Coolera Peninsula to the west of Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic.

The Carnac stones are an exceptionally dense collection of megalithic sites near the south coast of Brittany in northwestern France, consisting of stone alignments (rows), dolmens, tumuli and single menhirs. More than 3,000 prehistoric standing stones were hewn from local granite and erected by the pre-Celtic people of Brittany and form the largest such collection in the world. Most of the stones are within the Breton municipality of Carnac, but some to the east are within neighboring La Trinité-sur-Mer. The stones were erected at some stage during the Neolithic period, probably around 3300 BC, but some may date to as early as 4500 BC.

Nordic megalith architecture is an ancient architectural style found in Northern Europe, especially Scandinavia and North Germany, that involves large slabs of stone arranged to form a structure. It emerged in northern Europe, predominantly between 3500 and 2800 BC. It was primarily a product of the Funnelbeaker culture. Between 1964 and 1974, Ewald Schuldt in Mecklenburg-Western Pomerania excavated over 100 sites of different types: simple dolmens, extended dolmens, passage graves, great dolmens, unchambered long barrows, and stone cists. In addition, there are polygonal dolmens and types that emerged later, for example, the Grabkiste and Röse. This nomenclature, which specifically derives from the German, is not used in Scandinavia where these sites are categorised by other, more general, terms, as dolmens, passage graves and stone cists.
The simple dolmen or primeval dolmen is an early form of dolmen or megalithic tomb that occurs especially in Northern Europe. The term was defined by archaeologist, Ernst Sprockhoff, and utilised by Ewald Schuldt in publicising his excavation of 106 megalithic sites in the north German state of Mecklenburg-Vorpommern. The simple dolmen emerged in the early days of the development of megalithic monuments of the Funnelbeaker culture (TBK) and around 3,500 BC they appeared across almost the entire region covered by the stone cult structures of Nordic megalith architecture, but not in the Netherlands, in Lower Saxony west of the River Weser nor east of the River Oder and only once in Sweden.
Hirebenakal or Hirébeṇakal or Hirébeṇakallu is a megalithic site in the state of Karnataka, India. It is among the few megalithic sites in India that can be dated to the 800 BCE to 200 BCE period. The site is located in the Koppal district, some 10 kilometres (6.2 mi) west of the town of Gangavati and some 35 kilometres (22 mi) from Hospet city. It contains roughly 400 megalithic funerary monuments, that have been dated to the transition period between Neolithic period and the Iron Age. Known locally as eḷu guḍḍagaḷu, their specific name is moryar guḍḍa. Hirebenakal is reported to be the largest necropolis among the 2000 odd megalithic sites found in South India, most of them in the state of Karnataka. Since 1955, it has been under the management of the Dharwad circle of the Archaeological Survey of India (ASI). On May 19, 2021, it was proposed that Hirebenakal be made a UNESCO World Heritage Site.

In 2015, the portal tomb or dolmen was in imminent danger of collapse and was excavated and restored by a team led by Kerry County Archaeologist, Dr Michael Connolly. Prior to the excavation of Killaclohane Portal Tomb, very little was known about Neolithic settlement in Kerry and the beginning of agriculture.
