Arsameia, the summer capital of the Commagene Kingdom, is located in the Kahta district of Adıyaman on the Nemrut route, bearing traces from the 1st century BC with Anatolia's longest Greek inscription, its 158-meter-deep tunnel, and rock reliefs; admission is free.
Located approximately 26 kilometers from Adıyaman's Kahta district, within the borders of Nemrut Mountain National Park, the Ancient City of Arsameia holds an important place in history as the summer capital and administrative center of the Commagene Kingdom. This archaeological site, also known as Arsameia on the Nymphaios, still vividly bears the traces of the reign of King Antiochus I.
Guide's Note
Arsameia Ancient City is a stop on the Nemrut Mountain route, housing historical remains belonging to the Commagene Kingdom. The vast majority of visitors find the dexiosis stele, depicting King Antiochus I shaking hands with Heracles, to be the most striking element of the site. Walking among the rock-carved inscriptions and ancient paths holds a special appeal for those seeking a calm and uncrowded atmosphere. Admission is free; there is a small sales point at the entrance where you can get basic necessities like tea and water.
To reach the site, you need to climb a rather steep staircase; therefore, it is recommended to wear comfortable shoes and prepare yourself physically. Visitors consider the view that opens up as they ascend to be a compensating factor for the fatigue. Although the area is not very large, it can be planned as a half-hour stop when combined with a visit to Nemrut.
However, some issues recently highlighted by visitors include:
- Access restrictions: The tunnel entrance and paths leading to the cave are closed due to earthquake and safety concerns; only two viewing platforms and the dexiosis stele can be visited.
- Maintenance deficiencies: It is stated that the information signs are rusted and damaged, and the general maintenance of the area is insufficient.
- Cave and surrounding cleanliness: There are reports of a significant fly problem in the closed cave area.
- Restaurant near the parking lot: Multiple visitors emphasize that the prices at the restaurant at the entrance are disproportionately high; alternative options may be considered.
About Arsameia: The Summer Palace of Commagene
Arsameia was used as the summer capital by King Antiochus I of Commagene, who reigned in the 1st century BC. Built on an east-facing slope on the banks of the Kahta River (anciently known as Nymphaios), the city stands out with both its strategic location and its artifacts reflecting the art of its period. Among the most striking elements still standing at the archaeological site today is Anatolia's longest Greek inscription. This inscription describes a cult area dedicated by Antiochus I to his father and the rituals performed there.
Despite the city being in ruins, two separate tunnels, rock reliefs, and platform remnants still allow visitors to feel the grandeur of that era. Its location directly opposite the Old Kahta Castle makes the view of the valley even more impressive.
When to Visit?
The most suitable periods to visit Arsameia are the spring (April-June) and autumn (September-October) months. During these seasons, the air temperatures are suitable for comfortably exploring the archaeological site, and the surrounding vegetation also provides a beautiful backdrop for photography. The Adıyaman region can be quite hot in the summer months; those planning a visit during this period are advised to prefer the early morning hours. In winter, it is necessary to check weather and road conditions before setting off.
Arsameia is best visited on the route after watching the sunrise or sunset at Nemrut Mountain, making the day much more productive. Most visitors combine these two points on the same day.
How to Get There?
By private car: When heading towards Nemrut Mountain from Adıyaman city center or Kahta district, Arsameia signs will be seen along the way. It is approximately 26 kilometers from Kahta, and the road is generally smooth asphalt.
By public transport and tour: Nemrut tours departing from Adıyaman or Kahta almost always include Arsameia in their itinerary. Contacting local tour operators in Kahta to arrange a day trip is a very practical option. Kahta can be reached by bus or minibus via Adıyaman.
Suggested Itinerary: A Day on the Nemrut Route
Arsameia is located in a position where it can be visited in a single day along with the majority of historical sites in the Nemrut region. The suggested route can be planned as follows: Watch the sunrise at Nemrut Mountain in the early morning, then visit the Arsameia Ancient City on your way down. The Cendere Bridge, located on the route, is another ancient structure that must be seen; this Roman-era bridge completes the historical richness of the region. Since all these areas are close to each other, a one-day tour by car will be very satisfying.
Photo Spots
Arsameia offers several different shooting opportunities for photography enthusiasts. The rock reliefs and Greek inscription provide impressive details for close-up shots. The tunnel entrance is an ideal spot for those who want to capture interesting frames with plays of light and shadow. From the platform on the hill, wide panoramic photos encompassing the Kahta River valley and Old Kahta Castle can be taken. During the golden hour, i.e., early in the morning or late in the afternoon, the light creates a much softer and more dramatic atmosphere.
Things to Know Before Visiting
Since the archaeological site is located on uneven terrain, it is important to wear comfortable and sturdy shoes. The inside of the tunnel is quite narrow and has steep steps; descending into the tunnel may be challenging for visitors with limited mobility. Therefore, the archaeological site is not suitable for wheelchair or stroller use.
Shaded areas in the region are limited; sunscreen, a hat, and sufficient water should be carried with you. Since admission is free, you do not need to purchase a separate ticket, but it is recommended to get information in advance as visiting hours may change.
Food and Drink
Food and drink options are quite limited in the immediate vicinity of Arsameia. The Kahta district is the most suitable stop for meals before or after your visit. Kahta has various restaurants offering regional delicacies. For those planning a long day, carrying snacks and plenty of water will be a practical precaution. Some guides accompanying Nemrut tours organize lunch breaks in Kahta.
