Brochs: the prehistoric castles of Scotland


In Scotland, the past is still very much present. In rural areas you can hear people speaking Scots Gaelic or Lowland Scots like their forefathers did. There are castles and stone circles all over the region. The most enigmatic remains from the past are the brochs.

Brochs are mysterious drystone towers dating to around two thousand years ago. Built without mortar or nails, they’re architectural wonders, yet nobody is sure what they were for.

The best example surviving today is the broch of Mousa, pictured above in this photo courtesy Wikimedia Commons. Built around 100 B.C., it still stands to its original height of 13 meters (43 ft). A stairway cleverly constructed inside the thick wall spirals up to the top, where a walkway offers a beautiful view of the surrounding countryside.

Archaeologists used to think brochs were fortresses, a sort of prehistoric castle. This idea has given way to theories that they were homes of the elite or even simple farmhouses. This former archaeologist thinks the original theory is more likely. To me they feel like forts, and are far more imposing than the standard homes of the day. Plus in Lowland Scots the word brough means fort. In Old Norse, the language of the Vikings, borg also means fort. The Vikings reused some brochs as fortified bases from which the ransack the countryside. Many brochs have earthen ramparts around them, or are located on easily defensible spots such as beside a cliff or on an island in a loch.

%Gallery-130017%It’s hard to say how many brochs there are in Scotland because archaeologists argue over which sites are brochs and which aren’t. Estimates vary from barely a hundred to almost six hundred. Most are clustered in the far north, especially on the windswept Shetland and Orkney islands. Researchers can’t agree on when they were built either. Most agree it was from about 500 BC to 200 AD, but they can’t get more precise than that. This was the Iron Age, when competing tribes fought over land and crafted elaborate weapons and jewelry.

Perhaps the oldest known broch is being excavated right now. A broch at Nybster in Caithness may date back to 500 or even 700 BC, although it’s unclear if these early walls constituted a broch or if the broch was built on top of it. Prince Charles visited the excavation this week. Charles studied archaeology at university and has even gotten the royal hands dirty on several excavations.

All this academic debate just adds to the mystery. Located in the rugged far north of Scotland, often in remote areas, they can’t fail to impress. The sheer effort and skill required to build them in such a hostile environment commands respect.

They have more mysteries to offer up too. Inside there’s often evidence for rooms, floors, or other structures, but none have survived in good enough shape to show what they were used for.

Photo of the Day (8.28.2010)

A peaceful and powerful scene from Orkney Island, Scotland. When I look at these rocks and think about how long they’ve been there, I picture them with roots connecting them to each other while keeping them grounded. I mean, really. They’ve been there a long, long time. Thanks to Flickr user localsurfer for adding this to Gadling’s Flickr pool.

Five stunning stone circles (besides Stonehenge)


Every year thousands of tourists flock to Stonehenge, the iconic stone circle on Salisbury Plain, England. While so much attention is focused on this site, especially with the recent discovery of another monument near Stonehenge, people often forget there’s more than a thousand stone circles in the British Isles and Continental Europe. Built during the Neolithic starting about 5,000 years ago, these sites are beautiful and have gathered a lot of strange folklore over the centuries, like the mistaken belief that they were built by Druids or giants. Here are five of the best.

The Ring of Brodgar, Orkney Isles, Scotland
The windswept Orkney Isles north of Scotland are covered in prehistoric remains. The Ring of Brodgar, seen above in this photo courtesy of Beth Loft, is built of thin, tall stones on a narrow isthmus between two lochs. Its architects obviously had an eye for dramatic setting. It dates to between 2500 and 2000 BC, a boom time for monumental building in the Orkneys. It’s the northernmost stone circle in the British Isles and also the third largest at 104 meters (341 ft) in diameter. Like many major circles it’s part of a network of sites, with tombs and single standing stones scattered in the area around it. Legend has it that the Vikings were so impressed with the Ring of Brodgar when they arrived in the ninth century AD that they worshiped their gods here. Some Viking Runes carved into the stones may support this theory.

Avebury, England
Bigger than Stonehenge, the site of Avebury just 17 miles north of Stonehenge consists of a massive stone circle 331.6 meters (1,088 ft) in diameter with two avenues of stones leading to a pair of smaller stone circles. Construction began around 2900 BC, roughly the same time as its neighbor. Other monuments, such as the mysterious artificial mound of Silbury Hill and the West Kennet Long barrow, an ancient tomb, are an easy walk away. During the Middle Ages the locals got religion and decided this pagan monument needed to go. They knocked over several stones until one fell over and crushed one of the vandals. Everyone thought this was just a legend until modern archaeologists dug up a fallen stone and found the skeleton of a man underneath with some 14th century coins in his pocket!

%Gallery-98480%Rollright Stones, England
This stone circle makes a fun day hike from Oxford. Most stone circles are pretty small. This one is only 33 meters (108 feet) in diameter but has some interesting details. One stone has a hole through which you can see a tall monolith called the King Stone in a nearby field. A nearby dolmen (a small roofed tomb of stone) is called the Whispering Knights. Legend says the circle and these two outlying monuments are a king and his knights who were turned to stone by a witch. Actually the circle and monolith were built by prehistoric people between 2500 to 2000 BC. The Whispering Knights date to about 3500 BC. In prehistoric times, the presence of one monument encouraged people to build more.

Drombeg Stone Circle, Ireland
Drombeg Stone Circle in County Cork is a tight little collection of stones 9 meters (30 feet) in diameter. It’s of a type known as a recumbent stone circle because the largest stone lies on its side flanked by two smaller ones. This was deliberate; the stone didn’t fall down. What this means is anyone’s guess, although the local claim that it’s a “Druid’s Altar” is fanciful because the circle dates to the Bronze Age, about 2000 BC, and the druids were priests of the Celts, who didn’t appear on the scene until around 300 BC. Radiocarbon dating on a burial found in the center of the circle yielded a date between 150 BC and 130 AD. Just like at the Ring of Brodgar, later people were attracted to the site. While Drombeg didn’t start out as a Druid’s altar, maybe it ended up as one!

The Stone Circles of Senegambia, Senegal and The Gambia
Stone circles in Africa? Yep, these monuments aren’t as grandiose as the ones in Europe but they’re equally mysterious. There are about a thousand of them in a region of central Senegal and Gambia, meaning there’s about as many stone circles here as in all of Europe. The stones are as tall as 2.5 meters (8 ft.), although some are only a foot or so high. They mark burials dating from the 3rd century BC to the 16th century AD. There’s a large concentration of them at Wassu, Gambia. Locals put small stones on top of them as a sign of respect. Not much is known about these stone circles but they are beginning to attract attention from the archaeological community. A certain Gadling blogger may be visiting them next year, so stay tuned.
