Arshamshat
Arsamosata (Armenian: Արշամաշատ, Aršamašat; Greek: Ἀρσαμόσατα) was a city in Armenian Sophene near the Euphrates. It was founded by King Arsames I of the Orontid Dynasty in the 3rd century BC. It was left and destroyed in the 1st century BC. In the Middle Ages it was called Ashmushat.
The city has been identified with the modern Kharput (Elazığ) . Others conjectured the location somewhere between Kharput (Xarberd) and Palu (Balu). It has also been identified as the abandoned settlement site known as Haraba, located some 60 km east of Elazig.
Much of that site now lies submerged under the waters of the Keban dam. It is not to be confused with Samosata.
No longer a residential bishopric, Arsamosata is today listed by the Catholic Church as a titular see.
