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.

Madrid day trip: Segovia


Madrid offers a wide range of interesting day trips, from a Renaissance castle and Spanish Civil War bunker to challenging hikes. My personal favorite is the ancient town of Segovia just on the other side of the Sierra de Guadarrama mountains. With a beautiful cathedral and castle, one of the best preserved Roman aqueducts anywhere, winding medieval streets, and delicious cuisine, it’s a great choice for a day trip or overnight stay.

The best way to get to Segovia is by bus, which takes a little over an hour. Segovia’s Wikipedia entry says a high-speed train gets there in half an hour, but the high speed train doesn’t go to Segovia, it goes to a station called Segovia several kilometers away from town. You have to take a bus from there. To get to the train station in Segovia proper you go on a local train that takes an hour and fifty minutes. Wikipedia has mistakes!? Shocking!!!!

Anyway, Segovia is a convenient, delightful trip from Madrid. The three big hits are the aqueduct, the cathedral, and the Alcázar, or castle. The Roman aqueduct dates to the late first century AD. Segovia, like many Spanish cities, was a Roman town and perhaps has more ancient roots. The aqueduct is one of the best preserved anywhere and stands 93.5 feet tall in some places and starts at a water source almost ten miles away. It supplied the city with water until the early 20th century. The Romans sure knew how to build things!

The Santa Iglesia Catedral is an impressive Gothic pile started in 1525 and consecrated after many remodels in 1768, making it possibly the youngest Gothic cathedral in Europe. The expansive Plaza Mayor stands to one side. Take time to sip a coffee at one of the many outdoor cafes and enjoy the view. Inside are a series of chapels with often gruesome art, like a dinner party atop a tree. Death is cutting down the trunk with his scythe while Jesus rings a bell. Everyone is ignoring Jesus and a demon is about to pull the tottering tree into Hell. Nice!

%Gallery-128499%Segovia is built on a promontory, and its 12th century castle, the Alcázar, sits at the highest end like the prow of a ship. A rectangular tower soars towards the sky, topped by a beautiful set of round turrets. Inside are the usual displays of armor, weapons, and medieval art that you’d expect in a castle, and a large artillery museum too. The most impressive part of the castle is the view from the top. You get sweeping vistas of the Renaissance skyline of Segovia with its many churches and old houses, as well as the rolling countryside around the city. It gets my vote as one of the best views you can get anywhere close to Madrid.

To learn more about Segovia’s past, check out the Casa del Sol Museo de Segovia. Here you’ll see prehistoric artifacts, Roman sculpture, Visigothic jewelry, medieval and Renaissance art, and tools from Segovia’s early modern period. It’s a great museum but easy to miss, so don’t miss it!

After seeing these sites, take a stroll through the medieval streets of the old town, a UNESCO World Heritage Site. Like Harar, Ethiopia, another medieval walled city that’s on UNESCO’s list, the labyrinthine streets and alleys can get you lost pretty quickly, but the city’s small enough that you won’t stay lost for long. Check out the local artisans specializing in ceramics, the food shops selling tasty meats and cheeses, and more than a score of Romanesque churches.

Segovia gets pretty full in summer, so book your hotel well ahead. Two hotels I’ve stayed at and enjoyed are Natura and Los Linajes. Spring and fall are better times to go, especially September when it’s still warm but the school groups and university backpackers have left. Winter can be bitterly cold.

There are plenty of places to eat. Many restaurants serve two local specialties: cochinillo, roast suckling pig; and Judiones de la granja, which is faba beans with chorizo, garlic, and, if you’re being traditional, a pig’s ear! For a cheap lunch option find a place offering menú del día, a set menu where you have three or four choices for appetizer, main course, and dessert with a drink included. La Taberna de Abraham Seneor at Calle Judería Vieja 17 & 19 in the old Jewish quarter serves up a filling one for €11.90. There are also numerous cafes with outdoor seating in good weather. My favorite place to sit is Plazuela de San Martín, where you can gaze out on a sparkling fountain, a 15th century house, and a Romanesque church.

Tomorrow I’ll be talking more about the Alcázar, my favorite castle in Spain, and Wednesday I’ll be exploring the many beautiful churches of Segovia. Stay tuned!

Archaeologists explore “Pompeiis” in Bulgaria and El Salvador


Pompeii is an archaeological wonder, an entire Roman town preserved by a volcanic eruption. Now archaeologists are investigating two other “Pompeiis” to learn more about the past.

In El Salvador, a team has discovered a village dating to c. 630 AD that was covered in volcanic ash. Joya de Ceren was sealed up so well that archaeologists have been able to examine corn cobs, the logs used to build homes, and even the paths leading through the village and how crops were planted.

Archaeology is generally biased towards big sites, both because they’re easier to find and because it’s easier to get funding to excavate them. Finding a small village that was inhabited by only 100-200 commoners helps us understand how the other half lived. The village has been declared a World Heritage Site.

At the Roman city of Nikopolis ad Istrum in Bulgaria, an archaeological team is working on another “Pompeii”. This Roman city was never buried in a volcanic eruption but it’s so well preserved, scientists make the comparison anyway. An archaeological team is exploring a temple to Cybele, a mother goddess.

I’ve been to Nikopolis ad Istrum and was very impressed. The city was founded by the Emperor Trajan around 101-106 AD. It was a major center of trade and culture until Attila the Hun trashed it in 447 AD. So it goes. Attila wasn’t very thorough and the town soon flourished again under the Byzantines. Today you can walk the streets, see the foundations of many buildings and even spot some of their decoration. You can even trace the sewers, which are a lot less stinky than they used to be.

Conservation victory: Serengeti highway plans cancelled


Plans to build a paved, two-lane highway through the Serengeti National Park have been canceled.

The road, which was supposed to bring better access to Lake Victoria, will possibly be rerouted further south to avoid having an impact on the Serengeti’s rich wildlife.

There’s already a gravel road across the park, but paving it would have attracted much more traffic and probably fencing. The U.S. government expressed concern, as did UNESCO, after a study showed the project would affect the annual migration of millions of animals that’s one of the wonders of the natural world.

This is a rare victory of common sense over unbridled “development.” It’s also an example of how being eco-friendly can be good for the economy. Tourism generates a major part of Tanzania’s income, and there’s no way a road cutting through the nation’s most valuable natural resource wouldn’t have had a negative impact.

Bengal Tigers to get special protection


The Royal Bengal Tiger and other animals are to get special protection from the government of Bangladesh.

The government is setting up a 300-member force to patrol the areas where the endangered tigers live. This is in reaction to recent poaching incidents targeting the tigers and well as other animals such as turtles and crocodiles. The poaching and smuggling of animals is a major international problem. There’s a huge demand for rare animals as pets, decoration, food, and as ingredients in traditional medicine. Many of the animals most in demand, like tigers and rhinos, are endangered.

Most of the Bengal tigers in Bangladesh live in the Sundarbans, a huge mangrove forest straddling the India-Bangladesh border. It’s designated as a UNESCO World Heritage Site for its incredible variety of wildlife and is an important tourist draw for both countries.
