Ani is a ruined and uninhabited medieval Armenian city-site situated in the Turkish province of Kars, near the border with Armenia. It was once the capital of a medieval Armenian kingdom that covered much of present day Armenia and eastern Turkey. The city is located on a triangular site, visually dramatic and naturally defensive, protected on its eastern side by the ravine of the Akhurian River and on its western side by the Bostanlar or Tzaghkotzadzor valley.
