Prehistoric Scotland
2008/9 Schools Wikipedia Selection. Related subjects: British History 1500 and before (including Roman Britain)
Archaeology and geology continue to reveal the secrets of prehistoric Scotland, uncovering a complex and dramatic past before the Romans brought Scotland into the scope of recorded history. Obviously, throughout this period there was no such thing as Scotland or a national identity. Successive human cultures tended to be spread across Europe or further afield, but focussing on this particular geographical area helps to find out about the origin of the remains and monuments that are still widespread, and to understand the background to the history of Scotland.
The extent of open countryside untouched by intensive farming, together with past availability of stone rather than timber, has given Scotland a wealth of accessible sites where the ancient past can be seen.

The deep prehistory of Scotland
Scotland is geologically alien to Europe, comprising a lost sliver of the ancient continent of Laurentia (which later formed the bulk of North America). During the Cambrian period the crustal region which became Scotland formed part of the continental shelf of Laurentia, then still south of the equator. Laurentia was separated from the continent of Baltica (which later became Scandinavia and the Baltic region) by the diminishing Iapetus Ocean. The two ancient continents moved toward one another through the Cambrian and Ordovician periods, with tectonic folding during the Silurian pushing the first Scottish land above water. The final collision occurred during the Devonian period, with the Scottish segment of the Laurentian plate smashing into Avalonia (which contained what is now most of England and Wales), a motile subcontinent which had previously joined with Baltica. This impact threw up a massive chain of mountains (at least as tall as the present-day Alps) and saw the formation of the granitic West Highland and Grampian mountain chains and (through the Carboniferous) a period of volcanic activity in central and eastern Scotland. During the Permian and Triassic periods, with the Iapetus Ocean entirely closed, Scotland lay near the centre of the Pangaean supercontinent. With the advent of the Tertiary, a constructive plate boundary became active between Laurentia and Eurasia, pushing the two apart (and parting Scotland from Laurentia forever). This recession opened the Atlantic Ocean for the first time, and the consequent subduction zone at the western plate margin led to a renewed period of vulcanism, this time on Scotland's west coast, producing fresh mountains on Skye, Jura, Mull, Rùm, and Arran.
This tectonic activity produced the basis of Scotland's topography: ancient mountains in the North and South of the country, partially eroded by 400 million years of water and ice with a wide fertile valley between them, and a newer, wilder western terrain. With Scotland now in the northern temperate zone, it was subjected to numerous glaciations in the Neogene and Quaternary periods, the ice sheets and their attendant glaciers carving the landscape into a typical postglacial one, overdeeping river valleys into the characteristic U-shape and leaving the upland areas covered with glacial corries and dramatic pyramidal peaks. In lowland areas the ice deposited rich fields of fertile glacial till and eroded the softer material surrounding the extinct volcanoes (particularly the older Carboniferous ones), leaving many crags.
Before modern humans
During the last interglacial, around 130,000 - 70,000 BC, there were times when climate in Europe was warmer than it is today, and after the Neanderthals came to prominence there was another mild spell around 40,000 BC. Neanderthal sites have been found in the south of England, and it is possible that early humans made their way to Scotland, though no traces have been found.
Glaciers then scoured their way across most of Britain, and it was only after the ice retreated that Scotland again became habitable, around 9600 BC.
Hunter-gatherers
As the climate improved mesolithic hunter-gatherers extended their range into Scotland.
An early settlement at Cramond, near what is today Edinburgh, has been dated to around 8500 BC. Pits and stakeholes suggest a hunter-gatherer encampment, and microlith stone tools made at the site predate finds of similar style in England. Although no bones or shells had survived the acid soil, numerous carbonised hazelnut shells indicate cooking in a similar way to finds at other Mesolithic period sites including the slightly earlier Star Carr and Britain's oldest house, the Howick house in Northumberland dated to 7600 BC, where post holes indicate a very substantial construction, and the finds are interpreted as being a permanent residence for hunting people. This suggests that hunter-gatherers could also have settled down in Scotland.
Other sites on the east coast and at lochs and rivers, and large numbers of rock shelters and shell middens around the west coast and islands, build up a picture of highly mobile people, often using sites seasonally and having boats for fishing and for transporting stone tools from sites where suitable materials are found. Finds of flint tools on Ben Lawers and at Glen Dee (a mountain pass through the Cairngorms) show that these people were capable of travelling well inland across the hills.
At a rock shelter and shell midden at Sand, Applecross on Wester Ross facing Skye, excavations have shown that around 7500 BC people had tools of bone, stone and antler, were living off shellfish, fish and deer using pot-boiler stones as a cooking method, were making beads from seashells and had ochre pigment and used shellfish which can produce purple dye.
Farmers and monument builders
Neolithic farming brought permanent settlements. At Balbridie in Aberdeenshire crop markings were investigated and ditches and post holes found revealing a massive timber-framed building dating to about 3600 BC. An almost identical building was excavated at Claish near Stirling. At the islet of Eilean Domhnuill, Loch Olabhat on North Uist, Unstan ware pottery suggests a date of 3200-2800 BC for what may be the earliest crannog.
The remainder of this section focuses mainly on the Orkney Islands, where there is a Neolithic landscape rich in sites amazingly preserved by prevalent use of the local stone which appears on the shore ready split into convenient building slabs. This is only a selection of highlights and there are many other examples across the country, often under the care of Historic Scotland.
At the wonderfully well preserved stone house at Knap of Howar on the Orkney island of Papa Westray (occupied from 3500 BC to 3100 BC) the walls stand to a low eaves height, and the stone furniture is intact. Evidence from middens shows that the inhabitants were keeping cattle, sheep and pigs, farming barley and wheat and gathering shellfish as well as fishing for species which have to be line caught using boats. Finely made and decorated Unstan ware pottery links the inhabitants to chambered cairn tombs nearby and to sites far afield including Balbrindi and Eilean Domhnuill.
The houses at Skara Brae on the Mainland of the Orkney Islands are very similar, but grouped into a village linked by low passageways. This settlement was occupied from about 3000 BC to 2500 BC. Pottery found here is of the grooved ware style which is found across Britain as far away as Wessex.
About 6 miles (10km) from Skara Brae, grooved ware pottery was found at the Standing Stones of Stenness (originally a circle) which lie centrally in a close group of three major monuments. Maeshowe, the finest example of the passage grave type of chambered cairn (radiocarbon dated to before 2700 BC) lies just to the east. The magnificent Ring of Brodgar circle of standing stones is across a bridge immediately to the north. This circle was one of the first to be analysed by Professor Alexander Thom to establish the likely use of standing stones as astronomical observatories. Another Neolithic village has been found nearby at Barnhouse Settlement, and the inference is that these farming people were the builders and users of these mysterious structures.
As with the standing stones at Callanish on Lewis and other standing stones across Scotland, these monuments form part of the Europe wide Megalithic culture which also produced Stonehenge in Wiltshire and the stone rows at Carnac in Brittany.
The widespread connections these people had is shown by offerings imported from Cumbria and Wales left on the sacred hilltop at Cairnpapple Hill, West Lothian, as early as 3500 BC.
Bronze age
The cairns and Megalithic monuments continued into the Bronze age, which saw metals as an additional material rather than a replacement for flint. However there was a decline in both the building of large new structures and in the total area under cultivation from about 2500 B.C.
The Clava cairns and standing stones near Inverness show complex geometries and astronomical alignments, with smaller perhaps individual tombs instead of the communal Neolithic tombs.
Mummies dating from 1600-1300 B.C. have been discovered at Cladh Hallan on South Uist.
Hill forts were introduced, such as Eildon hill near Melrose in the Scottish Borders which goes back to around 1000 BC and which accommodated several hundred houses on a fortified hilltop. Excavation at Edinburgh Castle found late Bronze Age material from about 850 BC.
Iron age
From around 700 BC extending into Roman times the Iron age brought an age of forts and defended farmsteads, which supports the image of quarrelsome tribes and petty kingdoms recorded by the Romans. Evidence that at times occupants neglected the defences might suggest that symbolic power was as significant as warfare.
Brythonic Celtic culture and language spread into southern Scotland at some time after the 8th century BC, possibly through cultural contact rather than mass invasion, and systems of kingdoms developed.
Larger fortified settlements expanded, such as the Votadini stronghold of Traprain Law, East Lothian, which was the size of a town. Huge numbers of small duns, hill forts and ring forts were built on any suitable crag or hillock. The spectacular brochs were built, most impressively the near complete broch at Mousa on Shetland. Many Souterrain underground passageways were constructed, though their purpose is obscure. Island settlements linked with a causeway to land, the crannogs, became common; it is thought that their function was defensive.
