Tumuli in the context of "Round barrow"

Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones which are held in place with mortise and tenon joints—a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside, these are free-standing trilithons, two bulkier vertical sarsens joined by a single lintel. The whole monument, now in ruins, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred tumuli (burial mounds).

Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 BC. The famous circle of large sarsen stones was placed between 2600 BC and 2400 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. Radiocarbon dating suggests that the bluestones were given their current positions between 2400 and 2200 BC, although they may have been at the site as early as 3000 BC.

The Burgstallkogel (458 meters or 1563 feet; also known as Grillkogel) is a hill situated near the confluence of the Sulm and the Saggau river valleys in Southern Styria in Austria, about 30 km south of Graz between Gleinstätten and Kleinklein. The hill hosted a significant settlement of trans-regional importance from 800 BC to about 600 BC. Surrounding the hill is one of the largest Iron Age necropolises in continental Europe, originally composed of at least 2,000 tumuli.

The Carnac stones (Breton: Steudadoù Karnag) are an exceptionally dense collection of megalithic sites near the south coast of Brittany in northwestern France, consisting of stone alignments (rows), dolmens (stone tombs), tumuli (burial mounds) 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.

Although the stones date from 4500–3300 BC, modern beliefs associated them with 1st century AD Roman and later Christian occupations. A Christian legend associated with the stones held that they were pagan soldiers in pursuit of Pope Cornelius when he turned them to stone. Brittany has its own local versions of the Arthurian cycle. Local tradition similarly claims that the reason they stand in such perfectly straight lines is that they are a Roman legion turned to stone by Merlin the Wizard.
