Brochs: the prehistoric castles of Scotland

by Sean McLachlan on


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.

Ancient port discovered in Egypt

by Sean McLachlan on


Archaeologists working in Egypt have discovered a harbor on the Red Sea that was used for international trade.

The excavation at Mersa Gawasis has revealed traces of an ancient harbor. It’s long been known that the Egyptians traded down the coast of Africa, but the location of their embarkation was unknown. A famous carving at Deir el-Bahari, the temple of Queen Hatshepsut, shows an ocean-going vessel like the one pictured above and scenes a land with thatched huts and exotic items for sale such as ivory and giraffes. Inscriptions identify the land as Punt but don’t mention where it is. Archaeologists have speculated that it was in the Horn of Africa, either in Eritrea or Djibouti, or where the modern unrecognized states of Somaliland or Puntland are today.

The first recorded voyages to Punt started in the reign of the Pharaoh Sahure, who ruled from 2487-2475 BC. Regular trading missions were sent out for centuries to buy exotic items for Egypt’s elite. Queen Hatshepsut’s famous engravings of Punt date to around 1490-1460 BC.

Scholars have traditionally been doubtful of the Egyptians’ ability to make long sea voyages. Further excavation at Mersa Gawasis may change this view and open up new possibilities for Egyptian influence on other ancient cultures. While the excavations at Mersa Gawasis are not yet open to public view, Deir el-Bahari is a popular attraction and you can wonder at the scenes depicting the mysterious land of Punt for yourself.

Excavating Central Park’s forgotten village

by Sean McLachlan on

Central Park is sometimes called the “lungs of New York City”. Locals and visitors alike come here to enjoy a bit of fresh air and greenery. The park was approved in 1853 in order to leave a green patch in the rapidly expanding metropolis. The city government took the land between 59th and 106th Streets, between Fifth and Eighth Avenues, by eminent domain. About 1,600 residents were paid for their property and forced to move by the summer of 1856.

While a beautiful park was born, its birth was the death of Seneca Village, a prosperous community of almost 300 people. Two-thirds of the population was black and it may have been the first community of middle-class black landowners is New York. The rest were white, many of them Irish immigrants. Of the village’s three churches, at least one was integrated.

Seneca Village was founded in 1825, two years before New York freed most of its slaves, and expanded quickly in the following few years. Living conditions downtown were unhealthy and property prices high (some things never change) so blacks with enough money were eager to move up to this area. The map, Columbia University, shows Seneca Village. Eighth Avenue is at the top of the picture. Seventh Avenue is at the bottom, with 82nd St. on the left and 86th St. is on the right.

Today archaeologists from the Seneca Village Project have finished the first-ever excavation of this historic community. After painstaking research through city records, they were able to locate the precise spots where many of the houses stood. They decided to excavate the property of two black residents: the yard of Nancy Moore, and the home of William G. Wilson. They found a wealth of nineteenth-century artifacts, including some porcelain imported from China, showing that some residents were quite well off. They even found a shoe that may have belonged to one of Mr. Wilson’s children.

Treasures of Teotihuacan go on display

by Sean McLachlan on


Teotihuacan is the New World’s most impressive city. Founded in the second century BC, it was a center of civilization for 800 years. Its Pyramid of the Sun has a greater volume than even the Great Pyramid at Giza, Egypt. Teotihuacan is located in modern Mexico just outside Mexico City. In a country filled with amazing ancient ruins, it’s one of the best.

An exhibit at Caixa Forum, one of Madrid’s leading art galleries, highlights the treasures of this civilization. Teotihuacan: Ciudad de los Dioses (Teotihuacan: City of the Gods) brings together some 400 artifacts and works of art to show the rise and fall of the city and its empire. The exhibition is divided into themed sections about the construction of the city, the arts, religion, palace life, and the mysterious destruction of Teotihuacan. Many of the objects displayed are beautiful, such as the inlaid jade masks and fearsome statues of the gods.

If you’re going to Mexico, I highly recommend that you visit this UNESCO World Heritage Site for yourself. I’ve been to a lot of ancient cities all over the world, but Teotihuacan simply blew me away.

Teotihuacan: Ciudad de los Dioses runs from July 27 until November 13.

Archaeologists explore “Pompeiis” in Bulgaria and El Salvador

by Sean McLachlan on


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.
