Things to Do in Osmaniye: Karatepe-Aslantas and Kastabala

The quiet corner of the Cukurova, and the great inscription inside it

Osmaniye is a province most people cross on the motorway on their way to Gaziantep or Adana. Let us say that plainly at the start: this is not somewhere you spend a few days. But on a hill in its Kadirli district sits one of the most important archaeological finds in Anatolia, and most travellers have no idea it is there.

Karatepe-Aslantaş is a Late Hittite fortress from the 8th century BC. What makes it unusual is that the carved reliefs and the bilingual inscription at its gates are **still where they were excavated**. Objects like these are almost always moved to a museum. At Karatepe they were not, and there is a reason for that: Halet Çambel. More on her below.

There is also an administrative muddle. Osmaniye belonged to Adana until 1996, and even after it became a province in its own right, many guides still file Karatepe under Adana. If your search did not find it, that is why.

Quick answer

Osmaniye is a small Cukurova province visited for the Late Hittite fortress at Karatepe-Aslantaş, with castles and Amanos highlands making up the rest.

• This is a day, not a holiday. Karatepe is half a day and the rest is driving.
• You need a car. Reaching Karatepe on public transport is not practical.
• Karatepe is in Kadirli, Osmaniye, not in Adana. Most guides get this wrong.
• The Cukurova is fiercely hot in summer; spring and autumn are the only sensible seasons.

1. Karatepe-Aslantas Open-Air Museum and National Park

The reason the province is on this site at all. On a hill above the Ceyhan river, a fortress founded in the 8th century BC by a ruler named Azatiwada. It has two monumental gates, lions at the south-west one and sphinxes at the north-east. The basalt orthostats around the gates carry hunting scenes, banquets, ships and gods, and all of it is still standing where it was carved.

That is the point of this place. Anywhere else in Anatolia, a relief sequence on this scale would have been lifted and trucked to Ankara or Adana. Here it was not, because Halet Çambel, who ran the excavation, resisted in the 1950s and won. The site became a national park in 1958 and was arranged as Turkey's first open-air museum in 1960.

The site is wooded and shaded, which in the Cukurova is a small mercy. The walk is stony and uphill. There is an indoor building for the smaller finds. Verify opening status and the state of post-2023-earthquake repairs officially before you drive out.

2. The Aslantas Dam and reservoir

Built on the Ceyhan between 1975 and 1984 for irrigation, flood control and power. The road to Karatepe follows the shore of the reservoir, and the view makes the drive a reason in itself.

But the dam earns its place in this guide for another reason. The original scheme would have raised the water higher and drowned a number of archaeological sites, Karatepe among them. Çambel intervened again and got the level lowered. Today Karatepe sits on a peninsula with water on three sides. Some sites, such as Domuztepe, were partly submerged anyway.

Access to the dam structure itself is restricted, as at any power installation, so verify arrangements rather than turning up. The shore road gives you places to stop and look.

3. Hierapolis-Kastabala

A Roman-era city spread across the plain near Osmaniye's centre. Its colonnaded street is still legible from the columns left standing, the theatre's seating survives, and bath and church remains lie scattered around.

Kastabala is a rougher experience than Karatepe. The site is largely open, signage is limited, and there is barely a marked path. In exchange, entry is free and you will usually have it to yourself, moving at your own pace.

A naming note: sources muddle this site. Some records label the city itself "Kastabala Kalesi", when the castle is a separate structure on the rock immediately above it. That is the next entry. Repair work has continued since the 2023 earthquakes, so verify which parts of the site are currently walkable.

4. Bodrumkale (Kastabala Castle)

A medieval castle on the rock rising roughly 45 metres out of the plain, just west-north-west of the Kastabala city site. Sections of its walls and towers survive. It looks down over the ancient city and across the Ceyhan plain, which is what actually repays the climb.

It goes by two names and this causes confusion: Bodrumkale and Kastabala Kalesi are the same building. It sits less than 200 metres from the ancient city, so plan the two as one stop.

The climb is short but rocky and uneven, so closed shoes matter, and there is no shade at midday in summer. This is a ruin, not a restored monument; set your expectations accordingly. Check its condition after the earthquakes officially.

5. Hemite (Amuda) Castle

A ruined castle on a steep crag above the Ceyhan river. Sources describe four towers; only the eastern one is standing today. It sits near the village of Gökçedam.

The castle's position explains why it is there: it controls the river crossing and the road out onto the plain. From the top you see the bend of the Ceyhan and the flat of the Cukurova beyond.

One note: sources disagree about which district it is in. The Culture Portal says Kadirli; mapping services and encyclopaedic sources say Osmaniye Merkez. Navigate to the village of Gökçedam rather than trusting the district name. The climb is steep and unmarked, so think about the weather and your footwear before starting up.

6. The Hemite rock relief

Carved into the south face of the rock below the castle, a Hittite warrior figure. You can make out the headdress, the rounded beard, a staff held up, and shoes with turned-up toes, all familiar markers of Hittite iconography.

Honestly: the relief is worn, and if you do not know what you are looking for you will struggle to separate it from the rock. It reads far better in raking light, early morning or late afternoon. Under midday sun it nearly disappears.

It is the same stop as the castle, a couple of hundred metres below. Coming here after seeing Karatepe's orthostats sets the protected and the unprotected versions of the same culture side by side. A small stop, but the context is strong.

7. Toprakkale

A castle on a mass of basalt right beside the motorway junction. The position is no accident: this is the mouth of the pass that links the Cukurova eastward through the Amanos range, and the castle watched that road for centuries.

Excavation is ongoing. It stopped after the 2023 earthquakes and restarted in September 2025. Because of that the site is closed to visitors: you can see the castle from the road and from around it, but you cannot go in. Check the dig's status and any opening officially rather than driving up to a locked gate.

Even so it costs nothing, because it is on your route: pulling over at the junction for a few minutes on the way to Gaziantep or Adana, and looking at that silhouette on the basalt, explains why this region is so thick with castles.

8. Savranda Castle

A ruined castle at 553 metres holding the pass up into the Amanos mountains, beside the Kalecik dam on the Kaypak village road. Its circuit is roughly 800 metres; sources disagree on the number of towers, so we will not give a figure.

Coming here is a choice. The castle is ruined: there are standing wall sections and tower remains, and nothing restored. The reward is the position. From above the pass you look at the Cukurova and the mountains at the same time, and why the castle went exactly there becomes obvious in one glance.

The road is narrow and winding, unsurfaced for the last stretch, and it turns to mud after rain. Do not attempt it in winter or bad weather. Verify current access and road condition locally.

9. Zorkun plateau

A highland in the Amanos range, inside pine forest. The road climbing up from central Osmaniye takes you out of the Cukurova heat into shade and cool air. This is where local people go in summer, and weekends get busy.

Set your expectations correctly: this is not a developed resort. There are no hotels and no organised facilities. There are tea gardens and seasonal businesses, most of them shut in winter. The reason to come is the view, the forest, and escaping the heat.

The road is a mountain road, winding and narrow in places. Late summer and autumn are its best window. If you plan to stay overnight, research first, because what is open changes with the season and nothing is guaranteed.

10. Haruniye hot spring

A thermal source at the foot of Düldül mountain, roughly 15 km north of Düziçi, within the boundaries of Kuşçu village and operated by the Düziçi district authority.

Here is something we have to be honest about: official pages carry inconsistent information about the facility's operating status, and we could not verify its current condition after the 2023 earthquakes. Calling the Düziçi Kaymakamlık to ask whether it is open beats arriving to find it shut.

We are not giving figures for water temperature, flow or any treatment claims; sources conflict and it strays into medical territory. If you are curious about Turkish thermal culture and are already near Düziçi, it is a reasonable stop.

11. Düldül mountain

The highest point of the Amanos range at 2,448 metres. People hike and camp here, and both Turkish and foreign groups come.

This is not a casual day out. Reaching the summit needs preparation, proper kit and preferably local guiding. Weather on the mountain changes fast, even in summer. Do not head up alone and unplanned.

Even if you have no intention of climbing it, the mountain explains the province's geography: the flat of the Cukurova stops abruptly and the Amanos range rises like a wall. Every castle in Osmaniye exists because it held a pass through that wall. You can see the mass of the mountain from the Zorkun road and from around Düziçi.

Why Karatepe matters

The short answer: the inscription at the gates gives the same text twice, once in the Phoenician alphabet and once in Anatolian hieroglyphs, which is to say in Luwian. A ruler named Azatiwada speaks in the first person, saying whose man he is, why he built the fortress, and what will happen to anyone who erases his name.

Popular accounts summarise this as "the Rosetta Stone of Luwian". That overstates it and is worth correcting. Hieroglyphic Luwian had already been partly deciphered in the 1930s; Gelb, Meriggi, Forrer and Hrozný had read a portion of the signs before Karatepe was found. Karatepe was an enormous windfall of text and a genuine breakthrough for content, but it did not deliver a correct sign inventory. Some of the faulty readings it entrenched actually delayed the recognition that hieroglyphic Luwian and cuneiform Luwian were the same language.

The work that fixed the sign values came in 1973, from Hawkins, Morpurgo Davies and Neumann. The interesting part is that the trigger came from outside Luwian territory altogether. Notes on Urartian pots were written in the hieroglyphic Luwian script but in the Urartian language, and they showed that a sign long read as a vowel was actually a syllable. That single correction set off a chain reaction that rebuilt the whole reading system.

The dating is less settled than it looks, too. The common position puts the inscription at the end of the 8th century BC, roughly 700. Against that, in 2021 Novák and Fuchs argued that Azatiwada's overlord Awariku may not be the Urikki of the Assyrian records but an earlier namesake from the same dynasty, which would put the fortress before 765 or between 765 and 740. The argument is not about the century, it is about who Awariku was. What a guide can honestly do is give the range: 8th century BC, usually placed around 700, with a serious objection on the table.

One line in the text: Azatiwada says that in the lands he rules, women now walk with spindles, meaning in places where men once feared to go. It is security propaganda written three thousand years ago and you can still tell exactly what it is doing.

Halet Cambel and the decision to leave the stones where they were

Knowing that what you are looking at is there because of one person's stubbornness changes the visit.

Halet Çambel was born in Berlin in 1916 and died in Istanbul in 2014. She competed in fencing at the 1936 Berlin Olympics and, with her teammate Suat Aşani, refused an invitation to meet Hitler on political grounds. She is often called the first Muslim woman to compete at the Olympics; sources hedge on that, not least because a teammate competed in the same event at the same Games. The safe statement is that she was among the first Turkish women to compete at the Olympics.

The archaeology is the real story. When Karatepe was found in 1946, Bossert led the excavation and Çambel was central to the team. In the 1950s the state wanted the reliefs moved to a museum. Çambel objected and argued for conserving them where they were carved. What you see today is the result of that fight: national park status in 1958, and in 1960 Turkey's first open-air museum. Small finds went into an indoor building; the orthostats stayed put.

In the 1970s the dam scheme on the Ceyhan threatened the same site, this time with water. Çambel got the level lowered and Karatepe survived. It has water on three sides now.

She was not only the excavator either: she was co-editor, with Hawkins, of the standard scholarly edition of the Karatepe inscriptions. She received the Prince Claus Award in 2004.

The UNESCO status, and a trap to avoid

There is an easy and consequential confusion here, so let us be precise.

Karatepe-Aslantaş is **not on the World Heritage List**. It was added to UNESCO's **Tentative List** on 14 April 2020. A tentative list is a shortlist of places a country may nominate later; it is not an inscription. Karatepe is also not among the sites Turkey is currently pushing an active nomination dossier for.

In 2025 headlines appeared saying Karatepe had "entered UNESCO", and they are true, but they refer to a different programme: the Karatepe inscriptions were added to the **Memory of the World** register. That is the documentary heritage programme and has nothing to do with the World Heritage Convention. Conflating the two is a common mistake.

And one more: **Arslantepe Mound** in Malatya was inscribed on the World Heritage List in 2021 and is **an entirely different site** from Karatepe-Aslantaş. The names are very close. Malatya's is **on** the list; Osmaniye's is a **candidate for** it.

Adana or Osmaniye

Karatepe is in the **Kadirli** district of Osmaniye province. That much is settled.

The confusion is historical: Osmaniye became a province in 1996, having been a district of Adana before that. Everything published before then, and most of the current content that copies it, files Karatepe under Adana. Some sources get the district wrong too and say Düziçi.

The practical upshot: search for "Karatepe-Aslantaş" in your map app rather than trusting a province name. From Adana it is about an hour and a half.

Getting there

You need a car. Touring this province on public transport is not realistic, least of all for Karatepe.

The nearest airports are Adana and Hatay. The city of Osmaniye sits on the motorway with good coach links, but once you leave it, reaching Karatepe, Kastabala or the highlands without your own vehicle is hard. If you are travelling the Gaziantep-Adana axis, Osmaniye is already on your route and a half-day detour for Karatepe makes obvious sense.

Karatepe is about 45 minutes from the centre via Kadirli, on good asphalt.

When to go

Spring and autumn. This is the Cukurova; the summer heat is serious, and touring a shadeless site like Kastabala at midday is punishment. Karatepe is wooded and therefore more bearable, but go early anyway.

Winters are mild but wet, and the unsurfaced approaches like Savranda's turn to mud. For the Amanos highlands and Düldül, late summer and autumn are the window, and roads can close in winter.

What to eat

Osmaniye's cooking is Cukurova cooking: kebab-led, spicy, inside the same tradition as Adana. The province is not a food destination in its own right and lives in the shadow of its neighbours, which is worth saying plainly.

What it does stand out for locally is peanuts; Osmaniye accounts for a significant share of Turkish production, and in season you find them fresh at the roadside. The tradesmen's restaurants in the centre serve kebab and breakfast at a solid standard.

Frequently asked questions

Is Osmaniye a destination?

No, and that is the honest answer. This is a place you come to for Karatepe and see in half a day. If Adana, Gaziantep or Hatay is on your route, adding Karatepe makes a great deal of sense; setting out for Osmaniye alone does not.

Is Karatepe in Adana?

No, it is in the Kadirli district of Osmaniye. It belonged to Adana until 1996, which is why older sources still say Adana.

Is Karatepe a UNESCO World Heritage Site?

It is not. It joined the Tentative List in 2020 and is not inscribed. What entered a UNESCO register in 2025 was the inscriptions, on the Memory of the World programme, which is separate. Arslantepe in Malatya is on the World Heritage List, but that is a different place.

How long does Karatepe take?

Between two hours and half a day, depending on how much you read. Knowing what the reliefs mean changes the visit completely; arrive unprepared and it looks like a row of stones.

Are Kastabala and Bodrumkale the same place?

No, but they are next to each other. Kastabala is the Roman city on the plain; Bodrumkale is the medieval castle on the rock above it. They are less than 200 metres apart, so plan them as one stop. Some sources label the city itself "Kastabala Kalesi", which is where the confusion starts.
