Sarkel

Listen to the wind first. Out here in the Don country it comes across the steppe with almost nothing to stop it. It carries dry grass, river damp, and a faint smell of earth. The land runs low and wide, and the sky takes up most of what you see. For more than a thousand years, people have looked at this same flat horizon and asked one question: where can we build something that will hold?

Sarkel was one answer to that question. It was a fortress of the Khazars, a powerful steppe people. In the ninth and tenth centuries they controlled much of the land between the Black Sea, the Caspian Sea, and the Volga River. Before we go further, one honest note. The fortress itself does not stand inside Belaya Kalitva. Its remains lie further down the Don, near Tsimlyansk, in the same Rostov region. The name still carries weight across this whole stretch of river country.

The river system ties these places together. Belaya Kalitva sits where the Kalitva River meets the Seversky Donets. The Seversky Donets in turn flows into the Don. For the Khazars, rivers like these were roads. Boats carried goods, and riders followed the banks. Whoever controlled a crossing on the Don controlled a gate between the steppe, the forests to the north, and the markets of the south.

Here is the first surprise. Sarkel was not built by the Khazars alone. A Byzantine emperor, Constantine the Seventh, wrote about it in the tenth century. His book was a handbook on foreign peoples. According to his account, the Khazars asked Constantinople for help, and the empire sent builders. They were led by an officer named Petronas. Most historians date the work to the 830s. So a fortress on the open steppe was partly the work of engineers from the Mediterranean world.

The builders faced an unusual problem. The steppe near the Don had very little good building stone. According to the Byzantine account, Petronas solved it with fire. His crews made bricks by burning clay in kilns, and they built the walls from fired brick. This was Mediterranean technique carried hundreds of kilometres inland, to a place where most buildings were made of earth, timber, or felt.

The name gives us a clue to how the fortress looked. Sarkel is usually translated from the Khazar language as "white house" or "white fortress". The Byzantines gave it a Greek name with a similar meaning, often rendered as the White Inn. Picture pale walls rising above brown summer grass. On a flat steppe, a light-coloured wall could be seen from far away. It was a signal as much as a defence.

What did the fortress actually guard? Historians still debate the details. Some see Sarkel as a defence against new nomadic groups moving across the steppe. Others stress trade, with customs and control of river traffic on the Don. These purposes probably overlapped. A garrison, a crossing, and a market often grew together in this world. The walls protected people. They also protected the right to collect taxes.

Then came the turning point. In the 960s, Prince Sviatoslav of Kiev led a campaign against the Khazars. The early Rus chronicles record that he took the fortress. The Khazar state did not recover its old strength after these wars. The Rus gave the place a new name, Belaya Vezha. In the Slavic language this also means "white tower". The colour of the walls survived the change of rulers, even when the language changed.

After the conquest, the fortress became a Slavic settlement on the edge of the steppe. People lived inside and around the old walls for generations. The settlement lasted until around the early twelfth century. Pressure from steppe nomads then grew too strong, and the inhabitants left. The white walls stood empty above the Don. Slowly, grass and soil covered the brick.

The second surprise is a modern one. You cannot walk inside Sarkel today, because it is under water. In the twentieth century the Soviet state built a large dam on the Don. The Tsimlyansk Reservoir filled in the early 1950s and covered the fortress site. Before the flooding, the archaeologist Mikhail Artamonov led major excavations there in the 1930s and again around 1950. His teams worked against a deadline. They recorded walls, towers, houses, and graves before the water rose.

Those excavations changed how scholars understand the Khazars. Very few written sources from the Khazars themselves have survived. Most of what we know comes from their neighbours — Byzantines, Arabs, Persians, and Rus chroniclers. Sarkel gave researchers physical evidence: brick, pottery, tools, and the layout of a planned fortress. Many of the finds went to the State Hermitage Museum in Saint Petersburg. Pieces of this steppe story now sit in display cases far to the north.

So how do you experience Sarkel from here? You do it through the landscape. Look at the wide, low ground and the way the rivers cut through it. Notice how a single tall building, a hill, or a water tower draws your eye from far away. That effect explains why a pale brick fortress mattered so much. On this land, anything built upright becomes a landmark. People travelling by river or horse would have seen it long before they reached it.

As you stand here, let the scale settle in. Somewhere down the Don, under calm water, lie the foundations of a fortress planned by Byzantine engineers for a steppe empire. Rus warriors captured it, Slavic families lived in it, and Soviet archaeologists raced to record it. Listen again to the wind moving over the grass. It is the same open country those builders saw. As you walk on, watch the horizon, and think about what it takes to make anything last out here.
