Neolithic and Bronze AgeThe Long Rock takes some finding, concealed as it is (was?) by a small wood and a blanket of ferns. It is 2.4 meters long with a smooth face that used to lean towards the southeast and tapers slightly at the top.

Neolithic and Bronze AgeDespite looking very difficult to get to on my maps, this lateral entry allée couverte to the southwest of Loguivy is actually very easy to find, as a new housing developement has been made, with the roads through it signposted to the allée couverte, and then a little trackway made up to it.

Early MedievalEarly Christian cross, round tower, rare medieval monastery complex, holy well, bullaun stone and rag tree. The monastery was founded by St Ciaran the Elder in the 5th century, which makes Saighir one of the earliest church/monastic sites in Ireland, older than Clonmacnoise and older than St. Patrick by the tradition that made Ciaran one of the pre-Patrician saints.

Springs and Holy WellsThis must be the most unusual location for a holy well. The well is in the cave and only accessible at low tide. Water seeps from the multi-coloured rock and mothers formerly crossed the sands of Holywell Bay to immerse their ailing children in the healing water. Real pagan magic here with no obvious Christianisation.

Roman, Greek and ClassicalThree semicircular apses open off a square central space, roofless now, the fill of the vaults showing where the tiles have gone. This was a Roman tomb, built in the fourth century for the owners of a wealthy villa whose remains lie scattered about a hundred metres away. The masonry is original: small blocks of tufa laid in courses, in the technique called opus vittatum, with brick used inside and tufa outside.

Modern SitesThe experimental earthwork on Overton Down, its bank and ditch cut into the chalk in 1960 so that archaeologists could watch how such a structure weathers and settles. The posts along the crest belong to the monitoring. The point of the exercise was and is to dig sections through it at planned intervals over more than a century, and so measure decay against a known starting point rather than infer it.

Neolithic and Bronze AgetheCaptain writes: I thought I had seen some pretty impressive megalithic constructions before, but the Locmariaquer ones are making me think again. This is a massively long passage grave, built in at least two different ages, and much repaired/restored with slabs of concrete. We have many more pictures on our page, including some from the inside.

Neolithic and Bronze AgeNot far off the busy road between Morlaix and Roscoff, this Tee shaped allée couverte is apparently a very good example of the type, but it has become very overgrown and unloved, almost part of its surrounding field.

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.

Multi-periodFormer capital of the Nabataeans, half built and half carved into the cliffs. Petra is without doubt Jordan’s most valuable treasure and world heritage site. A vast, unique city, carved into the sheer rock face.
