Kahta Yenikale is situated 60 km. away from Adıyaman, 20 km. north of Kâhta, in the vicinity of the village of Kocahisar (Old Kahta). The castle is located on the road route of Karakuş Tumulus, Cendere Bridge and Mount Nemrut, directly opposite the old castle on the Arsameia hill. Its imposing appearance on the summit of a steep and high mountain attracts attention. The precise date of construction and the identity of the builders are unknown. However, it is thought that the first construction dates back to the Komagene Kingdom period. Over the following centuries, the castle has survived to the present day, with the additions made during the Roman, Artuqid, Seljuk, Mamluk and Ottoman periods. The castle comprises two distinct sections, namely the inner palace and the outer palace. Additionally, it contains a bazaar, a mosque, a dungeon, a cistern, waterways, dovecotes, and inscriptions. The inscription on the entrance gate of the castle bears the names of the Mamluk Sultan Kalaun, the inscription on the mosque bears the name of Melik Eşref Selahaddin Halil, and the inscription on the entrance gate of the palace bears the name of Melik Nasır. The dovecote on the southern slope of the castle can be reached by hidden stairs. These structures were built to raise pigeons, which were used to facilitate communication within the state and to deliver mail. There are 32 roosting places. As one descends, secret passages provide access to the other side of Kahta stream and offer an escape route from the castle in the event of an attack. The castle, which underwent partial repairs in the 1970s, was subsequently restored in 2012 at the initiative of the Ministry of Culture and Tourism.
