century BC, the temple was converted into a summer palace for Khosrovidukht (sister of Tiridates III of Armenia) by the Arsacid dynasty of Armenia. After the fall of the Arsacids, Armenia was ruled by a succession of aristocratic families called Nakharar. One of these Nakharar princes, Grigor Mamikonian, built a palace in the citadel of Aruch near the Aruchavank cathedral, some walls of this palace and a unique Armenian throne made of tufa still survive today. The Medieval capital of the Bagratid kingdom of Armenia, Ani, also hosted many palaces. The first palace of Ani, constructed by the princely Armenian Kamsarakan dynasty in the seventh century, served as the most important structure of the city. Located in the main citadel, the Kamsarakan palace was used by the successive Bagratid kingdom as their headquarters.
