During the Kingdom of Armenia (antiquity), many palaces were constructed for the successive kings. Ruins of a royal palace can be found in the early Armenian capital of Yervandashat, which was built to serve as the seat of Orontid Armenian Kings by Orontes IV. During the period of the Artaxiad Dynasty of Armenia, emperor king Tigranes the great constructed a grand persianate palace in the newly built city of Tigranocerta. The purpose of the Armenian Temple of Garni is still up for debate, however, certain scholars attest that following the Christianization of Armenia in the 4th century BC, the temple was converted into a summer palace for Khosrovidukht (sister of Tiridates III of Armenia) by the Arsacid dynasty of Armenia.
