Avebury, Wiltshire
Another of the incidental joys of Avebury, ignored by many visitors, or at least taken in with a rapid glance, is this dovecote. It is not the first dovecote I’ve posted in the long history of this blog, which is in part here to celebrate buildings that are out of the ordinary run of domestic, religious, or industrial architecture (although there’s plenty of all that here too). I particularly like many dovecotes because they are round – a shape that’s visually pleasing but also well suited to an internal design in which a central post carries a ladder that can be rotated so that one can reach any one of the hundreds of nest boxes inside.
Like the museum in my previous post and the stones in Avebury’s great prehistoric circle, this building is made of sarsen stone, with a couple of details in brick. This helps this out of the ordinary structure belong in its grassy spot among a collection of buildings, including the wooden barn that houses one of Avebury’s two museum spaces and the stone stables now occupied by the other museum. Stables, barns, dovecotes: this corner of Avebury would once have been home to a variety of creatures. Now the human animal – behaving in an admirably civilized manner when we were there – is the most usual living thing, its English variety frequently in search of coffee or tea.

Marking time
A refreshing if cold winter morning walking around the great stone circle at Avebury brought many pleasures, as it always does. The site was empty enough for us to take in the stones as individual objects, their chipped and pitted surfaces periodically lit up by the sun, and one could also enjoy the great sweeping arcs of the stones and earthworks – we were reminded yet again how much sheer work must have gone into the shifting of earth with wooden or antler shovels thousands of years ago.
Avebury also brings incidental pleasures. This is the Alexander Keiller Museum, named for and founded by the man who excavated in and around Avebury in the 1930s (funding the work with money that came from his family’s business making jam and marmalade). The museum is housed in a building that started out as the stables for nearby Avebury Manor, a structure variously dated to the 17th and 18th centuries. Like a lot of Avebury, it is built of the same hard sarsen stone as the standing stones themselves – tough stuff that’s generally used in large blocks, cutting it without modern machinery being extremely heavy work. The largest blocks here are the single stones used as lintels for the doors and windows.
The chunky look of the stone walls is beautifully offset by the treatment of this end gable, which metamorphoses into a clock tower and ends in a delicate hexagonal bell turret. I don’t know how long the carpentry work of the turret has been there, but its turned shafts and rounded arches certainly don’t look out of place on a 17th-century building, and whoever renewed them has produced something in what feels to me a fitting style. The clock face has gilded numerals and central sun rays that seem to belong in an earlier era too. It seems right, the horses having vacated the building, that it found a new and continuing use housing relics and records of Avebury’s history and excavation.*

* The museum was not open when I was recently at Avebury, due to restrictions imposed by the coronavirus, but the site is open as always and the National Trust’s café was doing a good job of offering a safe and distanced service, with tables outdoors for those dressed for winter as well as tables inside.

More uses for face masks
One of my favourite passages in Andrew Ziminski’s excellent book The Stone Mason: A History of Building Britain, is quite near the beginning, where the author describes his attempts at working sarsens, the materials used for the enormous prehistoric stone circle at Avebury and also for the nearby Dissenters’ Chapel. The chapel was originally built in 1670 using in part bits of sarsen obtained by chopping up chunks of some of Avebury’s standing stones. The point is that sarsen is very hard stone (up there with granite) and Ziminski wanted to try working it using the kind of tools available to Avebury’s prehistoric craftsmen. In other words he’d be working stone with stone – rounded lumps of sarsen or flint, which he’d use to pound away at the surface of the stone to cut into it or to smooth its surface.
Using stone tools like this, Avebury’s builders (working at some time between 2850–2220 BC) managed to prepare and position around 100 stones, as well as building a large circular bank and ditch – the resulting henge is so large that the modern village of Avebury sits inside it. And this stone circle is only part of the picture. It sits in a whole landscape of ancient sites – barrows, the causwayed enclosure of Windmill Hill, the stone circle at the Sanctuary, the vast mound of Silbury Hill – stretching for miles around. The integration of stones and landscape also makes Avebury a wonderfully atmospheric place – it is my favourite English prehistoric site.
Ziminkski discovered that walloping away at a large lump of sarsen with stone tools like those used in the Neolithic soon raises a huge amount of white dust; since sarsen is made essentially of silica, this dust can be dangerous to human lungs. Anyone doing this Neolithic job in the 21st century needs a face mask. Even so, it took a whole day of pounding to produce about a square foot of approximately smooth stone. This might lead us to conclude that in Stone Age Avebury there was a lot of labour available, and there might well have been. But Ziminski makes another point. Like other kinds of stone, sarsen gets extra hard when it has been exposed to the elements for a long time. If you quarry stone that has been beneath the earth’s surface it contains much more moisture, or ‘quarry sap’ as stone workers call it. Stone containing all its quarry sap is softer and easier to work and it was probably knowledge of this secret that made monuments like Avebury and Stonehenge possible. And also buildings like the Dissenters’ Chapel, which Ziminski had come to Avebury to repair. For that job, the stone mason could use his modern steel hammer, punch, and claw tool.

Avebury, Wiltshire

This is one of England’s most magical places. The vast stone circle, so big it encloses the entire village, and the archaeological landscape in which it sits, make up a complex whole that is rightly a World Heritage Site. Sometime between c. 3700 and 2200 BC, people in this part of Wiltshire constructed earthworks, arranged the large stone circle, erected other standing stones and stone alignments, and raised up long barrows to bury their dead.
Although the people who erected the stones lived millennia ago, there is a feeling of continuity too, whether in the happy combination of field walls and cottages made of the same hard sarsen as the standing stones, or in the fact that later houses, not to mention Christian places of worship, have been built within the vast stone circle. This combination of ancient stones and earthworks and a modern community living amongst it all is one of the things that makes Avebury special.
The exact dates, construction methods, and precise purpose of most of Avebury’s monuments is not known exactly, but the sheer size of the site makes its importance obvious. The careful alignment of the stones, the way in which they engage with the patterns of the movements of the sun and moon, point to a religious use. So does the atmosphere of the place. As one walks around the site, seemingly endless stones are revealed, and a combination of trees, deep ditches, and steep banks creates a play of shadows and light, of mystery and revelation.
Many have responded to the atmosphere of Avebury. The painter Paul Nash, for example. In his contribution to Herbert Read's Unit One anthology of 1934, he wrote: ‘Last summer I walked in a field near Avebury where two rough monoliths stand up, 16 feet high, miraculously patterned with black and orange lichen, remnants of an avenue of stones which led to the Great Circle. A mile away, a green pyramid casts a gigantic shadow. In the hedge, at hand, the white trumpet of a convolvulus turns from its spiral stem, following the sun. In my art I would solve such an equation.’ Stones, earth, lichen, and flowers: all followed the sun and do so still.
