Orpheus's Monument stands in front of the town tower in the middle of Slovenian Square (Slovenski trg) in Ptuj. This narrow, five metre high monolith of Pohorje marble is the symbol of the town, its former pillory and the oldest public monument in Slovenia preserved at its original location.

The white monolith was erected in memory of Marcus Aurelus Vera, the mayor of Petovio in the second century. It is decorated with depictions from Orpheus's story. On the wider front plate there is the traditional ornamentation known from the schemes of temple fronts. Above the triangular front there is a decorative ending with lions' heads and figural masques, lower there is the chiselled Orpheus playing among the animals. Below the inscription tablet are added reliefs, attached to Evridika's salvation from the underground. Reliefs with images of animals are on the narrower parts of the stone as well. In the Middle Ages the monument on its pedestal was used as a pillory, a pillar of shame on which wrongdoers were chained in iron rings.
