Tempelbezirk im Altbachtal, Roman temple district in Trier, Germany

Tempelbezirk im Altbachtal is a Roman archaeological site in Trier containing remains of more than 70 religious buildings from different periods. The structures range from wooden buildings to stone constructions and show how this sacred place developed over several centuries.

Excavations from 1926 to 1934 revealed different building phases starting from Augustus' time with wooden structures that were later replaced by stone buildings. This transformation shows how Roman presence and prosperity in the region increased during the first two centuries after conquest.

The sanctuary served mainly the local Treveri gods, whose imagery followed Roman models (interpretatio Romana); larger shrines were built as Gallo-Roman ambulatory temples. In the 4th century the cult of Mithras was added, and no Christian churches stood here. The site is now covered by allotment gardens, so the finds themselves are shown in the Rheinisches Landesmuseum Trier.

The excavated area was levelled after the Second World War and is now a Kleingarten allotment site, so the temples are not visible and there are no marked paths to follow. The finds, including the Epona relief and the Mithras relief, are held in the Rheinisches Landesmuseum Trier.

Rare reliefs and small statues were found at this location, including depictions of the goddess Epona and a bronze Mercury. These findings show the exchange between local and distant religious traditions.
