Arsameia ad Nymphaeum (Arsameia on the Nymphaios), located at the foot of Mount Nemrut in Eastern Turkey and known today as Eski Kale, was a royal seat and the summer capital of the Kingdom of Commagene, an ancient kingdom of the Hellenistic Age. It lays near the Nymphaios (Kahta Çay) River, a tributary of the Euphrates. Arsameia was named after King Arsames from Armenia who founded the Kingdom of Commagene around 260 BC. Its identification was based on a monumental inscription cut into the rock of a hillside to the south of Eski Kale. The ancient city extended to two opposite hills on either bank of the river. Scattered ruins from different periods can be seen on these hills today together with reliefs depicting dexiosis (handshake) scenes between deities and kings of Commagene.

Arsameia was first settled in the 3rd century BC by Arsames who fortified the city as part of his building of a power base against Seleucus II Callinicus (246-26 BC). It is here that, about a century later, one of the descendants of Arsames, King Mithridates I Callinicus, was to build his royal monuments and a cult center (hierotheseion). This made the city a place for worshipping the members of the royal house of Commagene.
The city was surrounded by walls and had a royal palace and luxurious public buildings. An inscription on the rock reports in detail the benefactions of Mithridates’ son, Antiochus I Theos, to Arsameia. Antiochus improved and expanded the palace, reinforced the city walls, secured water supply from nearby springs, constructed altars and dedicated statues to the royal family of Commagene. He also commemorated his father by building a hierothesion upon the Acropolis plateau of Arsameia and constructed a hierothesion for himself at Nemrut Dağ.
In the Late Roman and the Early Byzantine period, Arsameia declined and was restricted to a fortified position on the hill of the subsequent Yeni Kale (“New Castle”), the fortress built by the Mamlūk sultans.
Excavations carried out in the 1950s at the hierothesion at the top of the hill confirmed four periods of occupation; Hellenistic (2nd-1st centuries BC), Roman (1st-2nd centuries AD), Middle Ages (9th-10th centuries AD and 13th-14th centuries AD). The surviving ruins are located mainly at the top of the Eski Kale hill. A processional road that started from the Nymphaios River led to the side of the hill. Three reliefs depicting dexiosis scenes between deities and kings of Commagene define the path up to the sacred place. The best-preserved of all the relief stelae shows king Mithridates, dressed in Persian attire, shaking hands with Herakles (the Persian Artagnes). It stands above a remarkable rock-cut inscription which describes the founding of Arsameia.
There are several other important sites in the vicinity of the famous mountain of Nemrut Dagi including the Karakus Tumulus that served as the burial place of the female members of the royal dynasty of Commagene (Isias, Antiochis and Aka), and the incredibly well-preserved Roman Bridge at Cendere erected by four Commagene cities around AD 200 in honour of the Emperor Septimius Severus, his wife Julia Domna and his sons Caracalla and Geta (see here). This was the heartland of the small kingdom of Commagene.
I erected altars and sacred votive offerings as benefits the manes of my father in
accordance with my piety, and I have established statues and images of the gods, together with the representation of myself, lifelike in shape and form, for eternal memory’.
