Modern SitesTwo stones standing on the northern slopes of Metheral Hill, which turn out to be marked on the map as Boundary Stones. They are both about 5 - 6 feet tall, and on close inspection have a T carved in them. They have obviously been here a long time as they are all weather worn, so much so that I wonder whether they were ever anything else.

Neolithic and Bronze AgeTo the west of Metheral Circle is what looks like a ruined kerb cairn. Two of its kerb stones are still standing with other fallen ones where they fell. There seems to be a ruined cist within the center of the cairn.

Neolithic and Bronze AgeTwo ancient stone circles and a collapsed dolmen were recently rediscovered by Alan Endacott and team in the Taw Marsh area of northern Dartmoor, adding credibility to Endacott's theory that a “sacred arc” of monuments was built in the heart of the wild Devon uplands. He has named this the Metheral circle after the hill it stands beneath. The circle measures about 40 by 33 metres and consists of 20 stones, mainly fallen.

Natural PlacesTwo legendary rocks on Koh Samui island, Thailand, known as Hin Ta and Hin Yai Rocks (the Grandpa and Grandma rocks). For the not so observant, they resemble male and female genitalia. The beachside rocks, located between Lamai and Hua Thanon, raise indulgent chuckles or embarrassed titters from those who go to see them. Even stranger, they are close to one another, giving rise to a convenient legend explaining how they came into being.

Neolithic and Bronze AgeThis unique site on the Isle of Hoy, Orkney has attracted attention for centuries. It has been described as the dwelling place of giants, of dwarves, and as the home of an early Christian hermit. It was actually a tomb, related to the many chambered cairns found throughout Orkney. It dates to between 3500 and 2500 BC. Its construction, carved from a single enormous block of stone, is without parallel in Britain and Ireland. The labour involved, given the lack of metal tools, suggests that although small, it may have been of special significance.

Neolithic and Bronze Age To the west of Sortegård, Bornholm is a long stone which, according to old folk accounts, is said to have stood upright and can therefore be regarded as a Bautasten (Menhir). About 10 metres southwest of the menhir is a bench with several stones in front of it, including some Quern stones.

Neolithic and Bronze AgeEasily the most awe-inspiring prehistoric site in Scotland, the Ring of Brodgar lies on a promontory between two lochs. The stone circle is quite complete, and one of the biggest in Britain. The stones are set within a circular ditch up to 3m deep and 9m across that was hewn out of the solid bedrock by the prehistoric constructors.

Rock ArtHundreds of petroglyphs in Arizona, from the Hohokam era and before carved into the rocks. The site’s glyphs date to approximately AD / CE 800 at the earliest and are are of a variety of designs, depicting anthropomorphs (human-like figures, but archaeologists are unsure if they depict humans, deities, or something else), animals, and designs such as spirals. The meanings of most of the petroglyphs are unclear, however one of the spiral glyphs on the west face of the rock formation interacts with the sunlight in a way that indicates its use as a calendar. During each fall equinox and summer solstice, the light interacts with the glyph to form a “light dagger” through the center of the spiral.

Iron Age and Later PrehistoryA large univallate hillfort in Shropshire in a naturally strong defensive position on a steep sided spur at the north end of the Stiperstones ridge. Access is only along the ridge/spur. Most walkers on the Stiperstones route never visit Castle Ring, which is a shame as its situation is quite dramatic, with views across to many other hillforts in the area.

Multi-periodA well preserved layered tumulus in Mallorca. Built at the beginning of the Iron Age (850 BC) over an artificial funerary cave of the Bronze Age (1800-1500 BC). Initially the purpose of the tumulus was for ritual use but several centuries later the Bronze Age necropolis was re-used for the new burials, predominantly of the infants. The funerary use of the complex lasted till the beginning of the 3rd century AD.

Neolithic and Bronze AgeAt the end of a riding path and next to the footpath (formerly the Nærum-Vedbæk railway) stands a well preserved and clearly visible burial mound. The mound measures 20 metres in diameter and 2 metres in height. It is amazing it managed to survive this well preserved despite having the railway built next to it before these mounds were protected.
