According to historical and geographical sources, Totanjeh has been one of the important cities of Tabaristan in the early Islamic centuries. This city had a military function in the Abbasid period. In historical sources, Toranjeh has been recognized as Borji, Toranji, Torji, Tariji, Toranjir, and Tazhir which is located in the lowland zone between Mamatir (Babol) in South, Mileh (Southeast of Amol) in West and Sari in the East. The noteworthy political and military aspects have focused on the localization of Toranjeh city in early and medieval Islamic periods by historical sources and archaeological findings. On the base of documentary evidence, it can be given that the cultural sequence of the city of Toranjeh is divided into three phases. The formation of the Espahbodan Tabarestan reign, the development phase, and finally the collapse of the Samanid rule in the Mazandaran Marashyan period. The authors in the framework of a program of archaeological research surveyed Abolhasan kola-i- Babol located in the province of Mazandaran. The findings and review of archaeological and historical evidence suggest that the studied area (the village of Abolhasan kola-i- Babol) is the probable location of the city of Toranjeh.
