This week: Remarkable stones

According to the 12th-century cleric Geoffrey of Monmouth, the famous stones that make up the Stonehenge monument were erected originally in Ireland, before being moved to their current, more familiar home on Salisbury Plain. Geoffrey’s claim may seem fanciful, but…

Remarkable Stones Quiz

The historic boundary-marker known as the London Stone, indicating the downstream limits of the City's jurisdiction, is located at which point on the Thames Estuary?

Opposite This aerial view of the Gorseddau quarry shows how much infrastructure was needed to extract, work, and transport the stone. The stepped quarry at the centre is flanked on either side by a series of working platforms where slate blocks were turned into roofing slates. The four terraces to the left are connected by inclined planes, down which the worked slate was carried on rails on wedge shaped carriages. Waste stone was taken by tramway along each terrace to be tipped off the edge, creating the characteristic lobe shapes fanning out from the terraces.

Appreciating the Slate Landscape of Northwest Wales

On 28 July, UNESCO added the Slate Landscape of Northwest Wales to its list of World Heritage sites, which currently number 1,154. Chris Catling reports on the reasons for this inscription and marvels at the human ingenuity that has left us with a remarkable landscape combining natural and man-made features – fully worthy of being included in the top tier of all heritage sites in the world.

The exquisite results can be seen in Paget’s watercolour of bulls from one wall, and Howards Carter’s reproduction of a scene in which Thutmosis I and his mother Seniseneb make offerings to the god Anubis.

Above Excavations under way on Carn Menyn. Outcropping high on the Preseli Ridge, the bluestones used in the construction of Stonehenge were quarried from this region. A decade of survey in the area has identified a range of tantalising parallels between the Stonehenge and Preseli landscapes.

Stonehenge and Preseli: exploring the meaning of the bluestones

Why were the bluestones used in Stonehenge transported more than 200km from Preseli in Wales? The survey of the eastern Preseli Hills and investigation of selected sites by Timothy Darvill and Geoff Wainwright have exposed some uncanny parallels with the Stonehenge landscape. Could these help explain the meaning of the famous stone circle?

Opposite Prior Park, home of philanthropist Ralph Allen, who transformed Bath’s small scale stone mining industry into a major commercial venture. In the foreground can be seen the wooden railway Allen built to transport the stone. above An artist’s impression of working in the part of the quarry known as the ‘Grand Canyon’.

Hollowed Ground: the archaeology of Bath’s stone mines

The hills around Bath look solid enough but below the surface they are riddled with tunnels and stone quarries. When some of these began to collapse, putting the village of Combe Down at risk, Oxford Archaeology was called in to record this vast labyrinth before it was filled with concrete. Chris Catling reports on the record they made of an industry that helped create the beautiful buildings of Georgian Bath’s ‘Golden Age’.
