Varsan

Varsan, also called Warthan, was a medieval town on the Aras in the Mughan plain. A road from Ardabil crossed Mughan to the river here and continued through Baylaqan towards Barda, making the crossing part of a wider network between Iran and Arran. Islamic geographers described a prosperous market town with walls and a Friday mosque. The extensive fortified remains at Ultan Qalasi on the southern bank of the Aras lie at the site of this settlement, a Sasanian-period fortified city beside the river crossing.
