Neolithic and Bronze AgeTwo boulders bearing remarkable labyrinthine petroglyphs, in a pine wood beside the ancient Roman road connecting Viseu to Sao Pedro do Sul (known for its its thermal spa), about 300 metres from the village of Lufinha in the centre of Portugal. The two stones were probably once part of a single outcrop, broken up according to local legend by people pursuing a treasure hidden beneath the stone by a serpent. Photo Credit: Jose Neto

Iron Age and Later PrehistoryRecoded during excavations in 2008-2009 in advance of construction of the Weymouth Relief Road. Road construction affected only the western edge of the settlement, which may have been very much larger. The settlement was established in the 800-600 BC, the very earliest Iron Age, and appears not to have been enclosed at that time.

Early MedievalThe Ogham inscription has been translated as "of Sagranus son of Cunatamus?" and thought to be 5th- to early 6th-century in date. More close-ups on our page. A number of incised stones were found within the Abbey grounds; only the Sagranus Stone (pictured) is on display in the church - most are now displayed in the nearby Abbey Visitor Centre.

FunArtists Jimmy Cauty and Jem Finer have raised two standing stones, with a "modern ley line" between them. Inspired by this, I (Andy B) have built a 'Ley Line and Alignment Finder' which draws a straight line between any two of the Portal's 65,000-plus mapped sites and shows what sits along it. This is intended as a conceptual art project highlighting how we project modern thoughts onto ancient sites but it is for everyone to use however you wish. Here we look at a some classic alignments, then a how-to section so you can use the new tool to find your own conceptual 'ley lines' or alignments between any pair of sites of your choosing.

Neolithic and Bronze AgeNear Roughfort on the far outskirts of the city of Belfast. It looks like it has been cleared of a lot of vegetation that previous visitors complained of. Also known as Granny’s Grave (a corruption of Grania’s Grave which is itself a translation of Carn Greine = Cairn of the Sun), an overgrown, low, megalithic passage still roofed, 9 metres long. At the south-western end of is a sealed polygonal chamber which is roofed by a single stone 1.8 metres across.

Iron Age and Later PrehistoryThe site of the only known crannog in Wales. A dug-out canoe found some 400 metres from the site and now in Brecon Museum (pics on our page) has been radio carbon dated to between 760 AD and 1020 AD suggesting an age for the site. There is a reconstructed crannog house created on an island some 70 metres from the original crannog which has display panels and a replica of the canoe.

Neolithic and Bronze AgeA 1.4 metre tall standing stone on Cnoc a' Charragh (Hill of the Standing Stone) a remote, rocky location on the Isle of Colonsay. Just to the north lies another slab, 2 m by 0.8 m and at least 0.2 m thick. In 1923, S Grieve took it to be the cover of a long cist. This was examined and found to be empty. In 1984 RCAHMS thought it more likely a second, fallen standing stone. Creative Commons photo by Julian Paren,

Neolithic and Bronze AgeAn absolutely lovely site and well worth the visit as part of the Clunie Path. When the Clachan an Diridh stone circle was built, it would have had magnificent views to the NE across the River Tummel to Ben Vrackie and the Grampians beyond, and to the SW down the River Tay.

Neolithic and Bronze AgeFurther along the road to Ty-Lia allee couverte (see previous) after 100 yards a 5 foot standing stone is visible on the left. Walk through a gateway and the stone is under a tree, with three smaller stones nearby to the south on the other side of the tree and hedge.

Neolithic and Bronze AgeA fairly complete allée couverte, well signposted and in a little grassy area on the island of Ile-Grande, just off the coast near Trebeurden. It is about 9 metres long by 1.5 metres wide, and oriented to 110°. There are two large capstones which cover most of the chamber.

Neolithic and Bronze AgeWhat was originally a neolithic chamber is now bizarre in appearance, consisting of a capstone apparently delicately balanced on just two tall pointed supporting stones. Although difficult to reach, the effort required is worthwhile.

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.

Multi-periodAn earthwork enclosure located on the summit of Doon Hill c. 350m NNW of Kildonnan Farm on the B7042 between Sandhead and Portpatrick in Dumfries and Galloway. The rectangular grassy mound measures approx 20m east-west by 17.5m north-south. It is protected by an earth rampart and outer ditch.

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.
