The Apostolic Church of the East established bishops in nine cities in Afghanistan including Herat (424–1310), Farah (544–1057), Zaranj (544), Bushanj (585), Badghis (585) Kandahar, and Balkh. There are also ruins of a Nestorian convent from the 6th–7th centuries a short distance from Panj, Tajikistan on the north bank of the Amu Darya very close to the Afghan border, near Kunduz. The complex was discovered and identified by Soviet archeologists in 1967. It consists of dozens of small rooms carved into a rock formation.
