Neolithic and Bronze AgeTwo ancient cairns on a summit on the island of Fasta. The smallest cairn still has a part of a dry-walling, but most is collapsed during time. The site is visitable by a nice 500 m long footpath through a canyon, passing a small cave, a boulderfield and a tower.

Neolithic and Bronze AgeA recumbent megalith on North Uist 7m (23ft) long with a maximum width of 2m (6ft 6ins) and a minimum thickness of c. 40cm (16ins). It lies approximately north-south, resting upon half a dozen comparatively small stones which are in turn supported by an underlying cairn

Neolithic and Bronze AgeTwo recumbent stone slabs on the north-westerly side of the two summits of Craonaval, North Uist. They may mark the site of a burial but could be natural. There does not seem to be an associated cairn. The view is over Benbecula.

Multi-periodAn ancient bathhouse in Jordan best known for its colourful frescoes adorning its walls and ceilings. The site was made a UNESCO World Heritage Site in 1985. The paintings show the artistic transition between Byzantine culture and the new Islamic era. Additionally, the caldarium (hot room) of the bath house has a domed ceiling with the earliest known representation of the celestial dome painted on a non-flat, hemispherical surface

Neolithic and Bronze AgeBruce A writes:I was taken to a site on top of Jabal Fatouma on the ad-Deir plateau in Petra, southern Jordan, where I was shown this dolmen / propped stone. Despite research, I can find no reference to it. This spot is extremely difficult to get to and while the Bdoul Bedouin seem to find it easy, I struggled along a ledge less than the width of my boot, high up on the cliff face along Wadi Fatouma. I'm sure you could get to it if you started from the north-east, off the Baydah road; it would be a much easier, but longer, stroll.

Iron Age and Later PrehistoryA hillfort and Neolithic causewayed enclosure a few km south of Avebury. There are two circuits of bank and ditch plus a separate causewayed 'cross-dyke' outwork. A trial trench cut in 1963 found flint flakes and animal bones, while Neolithic sherds have also been found at the site.

Neolithic and Bronze AgeThe houses here are almost 10,000 years old, dug into the ground, plastered, and each was fitted with one or two pairs of clay pillars, set symmetrically either side of the axis of the chamber, with modelled tops. The pillars hold nothing up. They are not structural, so what they were for is an intriguing question.

Neolithic and Bronze AgeTwo burial mounds of the Corded Ware culture stand on the Kapellenberg above Hofheim am Taunus, raised somewhere between 2900 and 2350 BCE. They are the latest prehistoric monuments on a hill that had already been in use for well over a thousand years by the time they were built.

Neolithic and Bronze AgeHenge in Saxony-Anhalt. A replica of a mysterious wooden circle that is believed to be a temple of the sun built by a lost culture 6,800 years ago. The circle of posts, in a flat river plain at Goseck south of Halle, has mystified scientists since its discovery in 1991 by an archaeologist studying the landscape from the air. An excavation found post holes and what may be the remains of ritual fires.

Neolithic and Bronze AgeChambered Tomb in Guernsey. The most interesting of the sites to explore I think, this one has four side chambers similar in the style, if not size to West Kennett Long Barrow. You have to almost lie down to see the unique carving of a stylised face - 'the Guardian of the tomb', thought to be prehistoric in origin, possibly a reused carved menhir on the roof of the tomb.

Pre-ContactA bison jump used again and again for some two thousand years on the edge of the Alberta foothills near Cayley. A cliff of Paskapoo sandstone rises over the coulee, and at its foot the archaeological deposits reach more than six metres deep, the accumulated remains of drive after drive, still largely undisturbed toward the creek. Driving buffalo over a cliff was among the most productive of all plains hunting techniques, a way to take a great quantity of meat at once for drying and storage, and a successful drive demanded ritual, planning and the effort of the whole community.

Neolithic and Bronze AgeA standing stone in the grounds of the golf course at Sausmarez Manor. The current Lord of the Manor moved the menhir to this location from a spot NW of here near the road junction. Its origin is unknown, but the Folklore of Guernsey (Marie De Garis) book mentions many menhirs in this neighbourhood. It stands about 6 feet tall, and bears some marks of attempted destruction. Two of it's sides are smoothed flat.

Multi-periodA suggestion from one of our contributors that these carvings in India of a cobra approaching this disc carving represent a solar eclipse. Liesbeth continues: Many years ago Raja and I noticed reliefs depicting many different curious fish on a ceiling in the Kailasanatha temple in Kanchipuram. After Raja’s discovery of the eclipse depictions in a pavilion near Mamallapuram and in the Sangameshvara temple in Bhavani (Tamil Nadu) we decided to go back to Kanchipuram and check out this ceiling.
