The Adiyaman Archaeological Museum is situated in the city center. It is a one-story museum with three sections: coinage, ethnographic, and archaeological. The museum houses priceless artifacts that were uncovered during the prehistoric Commagene excavations. The head of the Commagene king Antiochos I was discovered in 1983 during the Samsat excavations. It is the museum's most uncommon artifact. The other famous item in the collection is the cult statue, which was founded during the Cirakli village digs in the Kilisik grave in 1970. The statue resembles those of Sanliurfa Gobeklitepe's peers. Additionally, there are tools from the Paleolithic era in the collection, along with items from the Hellenistic, Roman, Seljuk, and Ottoman eras.
