Tarḫuntašša

Stand still for a moment and face north. Behind the glass towers and palm-lined streets of Mersin, the Taurus Mountains rise in long grey-blue ridges. On a clear morning their peaks hold the light while the coast still sits in haze. Salt air comes off the Mediterranean behind you. Somewhere in that wall of mountains, more than three thousand years ago, lay a royal city that nobody has ever found.

Its name was Tarḫuntašša. The name honours Tarḫunt, the storm god of ancient Anatolia, the god of thunder, rain and mountain weather. For a short and dramatic period, this city was the capital of one of the great powers of the Bronze Age world. And yet today, no archaeologist can point to a hill and say with certainty, this is the place. That mystery is the heart of this story.

First, the people behind it. The Hittites ruled a large kingdom across central Anatolia, the high plateau of what is now Turkey. Their usual capital was Hattusa, far to the north, near the modern town of Boğazkale. The Hittites wrote on clay tablets in cuneiform, a script of small wedge-shaped marks. Thousands of those tablets survived, and they are the reason we know Tarḫuntašša existed at all.

In the early thirteenth century before Christ, a Hittite king named Muwatalli the Second did something unusual. He moved the capital away from Hattusa and south, to Tarḫuntašša. He took the gods of the kingdom with him, in the form of their sacred images. Historians still debate why. Some point to military strategy against Egypt in the south. Others point to religious reasons, or to pressure from enemies near the old capital.

The timing matters. Muwatalli was the king who faced the Egyptian pharaoh Ramesses the Second at the Battle of Kadesh, in Syria, around 1274 BC. It was one of the largest chariot battles of the ancient world. Both sides later claimed success. A southern capital put the Hittite king closer to that frontier, and closer to the roads that led through these mountains toward Syria.

The move did not last. After Muwatalli died, his son briefly ruled, and then the throne passed to Muwatalli's brother, Hattusili the Third, after a bitter family struggle. The capital returned north to Hattusa. But Tarḫuntašša did not disappear. It became a separate kingdom, ruled by a branch of the royal family, linked to the Hittite Great King by treaty. A city that had been the centre of an empire became a powerful, sometimes uneasy neighbour.

Here is the first surprise. In 1986, excavators at Hattusa found a tablet made not of clay, but of bronze. It records a treaty between the Hittite king Tudhaliya the Fourth and Kurunta, the ruler of Tarḫuntašša. The text carefully describes the borders of Kurunta's land, naming towns, rivers and mountains. Bronze treaties were mentioned in Hittite texts, but this was the first one ever found. Today the tablet is held in Ankara.

Those border descriptions are why this region matters to you, standing in Mersin. Many scholars believe the kingdom of Tarḫuntašša reached south from the inland plains toward this stretch of Mediterranean coast. The rugged country west of Mersin, which the Greeks and Romans later called Rough Cilicia, is often included in reconstructions of its territory. The exact lines remain uncertain, because many of the place names in the treaty have not been matched to real sites.

The search for the city itself has pointed in several directions. Some researchers look to the plains around Konya and Karaman, north of the Taurus. Others have studied sites in the Göksu valley, the river that reaches the sea near Silifke, west of here. Each candidate has arguments for and against. That is how archaeology works with an unlocated capital. Evidence slowly narrows the map, but rarely closes it.

The second surprise came recently. In 2019, a team working at a mound called Türkmen-Karahöyük, on the plain south of Konya, reported a large stone inscription. It was written in Luwian hieroglyphs, a picture-based script used in Anatolia. The text names a king called Hartapu and boasts of a victory over a rival land. Some scholars suggest this mound could be Tarḫuntašša itself, or a city closely tied to it. Others remain cautious. The question is still open.

It is worth pausing on what the end of this world looked like. Around 1200 BC, the Hittite kingdom collapsed, as did many states across the eastern Mediterranean. Trade routes broke, cities were abandoned, and writing in cuneiform stopped in Anatolia. Tarḫuntašša falls silent in the records at about this time. Yet Luwian-speaking kingdoms carried on in southern Anatolia for centuries, and the storm god Tarḫunt kept his worshippers long after.

So what can you actually see? Not a ruined gate or a palace floor with a clear sign. Instead, you can see the landscape the treaty described. Mountains with deep river valleys. A narrow coastal strip. Passes that connect the high plateau to the sea. These are the same physical facts that made the region valuable to Hittite kings. Roads through the Taurus still follow many of the old natural routes, because the mountains allow so few.

If you want objects rather than landscape, the museums are your best step. Finds from Bronze Age sites across this province and the plateau are displayed in regional collections, and the great Hittite material is in Ankara. Seeing a sealed clay tablet or a bronze figure helps the name Tarḫuntašša become real. It turns a line in a textbook into something made by human hands.

Now look north again, toward the ridges. Somewhere under fields, or under a quiet mound with goats and olive trees, a royal city may still be waiting. Kings once argued over its borders. Scribes wrote its name in wedge-shaped marks. As you walk back into the noise of modern Mersin, listen for the traffic, the gulls, the call to prayer. The past here is not gone. It is simply not yet found.
