A pristine marble statue of the messenger god Hermes, perhaps buried to protect it from overzealous Christianised Romans, was located in the sewers of Heraclea Sintica, a lesser-known ancient site near the border of Greece.

The Grego-Bulgarian border region was the site of the Macedonian kingdom of Philip II and Alexander the Great, and it's believed Philip II built Heraclea Sintica. The team of excavators said the statue is one of the finest ever found in Bulgaria.
