The Grotta del Mitreo lies on the slopes of Mount Ermada, overlooking the area where the river Timavo resurfaces after vanishing underground at Škocjan (ancient San Canziano) in present-day Slovenia, following a subterranean course of approximately 38 kilometres. Although the sanctuary was destroyed in the 5th century, several structural elements remain visible, including votive niches and the lateral benches where initiates would have gathered during ritual ceremonies. The location, in a natural cave close to the river’s resurgence, forms a significant part of the site’s setting.
