Whereas Hecatompylos had served as the first Parthian capital, Mithridates established royal residences at Seleucia, Ecbatana, Ctesiphon and his newly founded city, Mithradatkert (Nisa, Turkmenistan), where the tombs of the Arsacid kings were built and maintained. Ecbatana became the main summertime residence for the Arsacid royalty. Ctesiphon may not have become the official capital until the reign of Gotarzes I of Parthia (r. c. 90–80 BC). It became the site of the royal coronation ceremony and the representational city of the Arsacids, according to Brosius.
