Mithraeum I and III

Mithraeum I and III in Ptuj are among Slovenia’s most fascinating archaeological sites, offering a rare glimpse into the mysterious world of Mithraism—a Persian-inspired religion that flourished across the Roman Empire. Dating back to the 2nd and 3rd centuries, these ancient shrines are located near the Drava River, close to the remains of Roman villas, and are a testament to Ptuj’s (ancient Poetovio) significance as a bustling Roman city.

Mithraeum I and III are the best-preserved of five Mithras shrines discovered in Ptuj. Visitors can explore the foundations of these sanctuaries, where Roman soldiers and citizens once gathered to honor Mithras, the god of light and truth. Mithraeum III is especially notable for its well-preserved artifacts, including altars and reliefs depicting key scenes from the Mithraic mythos—most famously, the tauroctony, a dramatic statue of Mithras slaying a bull, and another showing his miraculous birth from a rock.

Guided tours of Mithraeum III are available by reservation, which must be made at least three days in advance. These tours provide valuable context about the rituals, symbolism, and cultural significance of Mithraism in Roman Ptuj. While specific opening hours and admission fees are not listed, the site is a must-see for history enthusiasts and anyone interested in ancient religions.

A visit to Mithraeum I and III is a journey into the spiritual life of Roman Poetovio, revealing the layers of history that make Ptuj one of Slovenia’s richest archaeological destinations.
