Antique Poetovio used to rank among the biggest centres of Mithraic religion in the Roman Empire.
The residential area called Zgornji Breg, a densly populated residential quarter of Poetovio, boasts the biggest Mithras Shrine discovered in 1913. It has been preserved under the protective building erected by the former Museum Society. The Shrine from the 3rd century is rich in sacrificial altars bearing dedications of legionnaires of the Thirteenth Gemina and the Fifth Macedonica Legions. The original equipment of the Shrine comprises a votive relief dedicated to sublime Nutrices, a bust of the goddess of fertility – Magna Mater, a relief altar brought here from a Mithras Shrine discovered in Modrič na Pohorju, and a relief plate depicting Saxan, the patron saint of stone masons, brought here from Šmartno na Pohorju.

The gate of the protective building of Mithra’s Shrine III (Zgornji Breg, Ulica k mitreju) is from July 3 2020 to August 31 2020 open from Tuesday to Friday from 10 a.m. to 4 p.m., Saturday and Sundays from 10 a.m. to 6 p.m. (Monday is Mithra’s Shrine III closed).
