A notable archaeological discovery has been made in Lenjan, Isfahan province, Iran, where an inscribed pottery fragment, or ostraca, from the Sassanid era was unearthed. This finding sheds light on the area’s historical commercial and industrial activities along the Zayandehroud River. The discovery, deemed significant for historical research, was made by the Lenjan Heritage Preservation Association during a scientific visit. The inscribed pottery, containing information about remittances and goods exchanges, highlights Lenjan’s role as a prosperous settlement. Experts believe this site was a key industrial hub during the late Sassanid era, potentially continuing into the early Islamic period.
