Farjollah Sedaqat took over official duties at Evin Prison in Tehran on Monday, the state-run news agency ILNA reported.
Sedaqat was previously the chief of judicial affairs at the Office of Prisons in Tehran Province.
His previous titles include warden of Qasr, Qezel-Hesar, and Fardis prisons.
Evin Prison was built by the Shahs regime as a maximum security prison to house political dissidents, but it became the Islamic Republics most dreaded gulag and the site of thousands of political executions.
