Titelberg is the location of the largest Oppidum (Celtic hillfort) of the Treveri tribe. It rose to its heyday in the first century BCE, as a prominent economic and political centre of the Treveri before the arrival of the Romans.

The Oppidum, situated on a hill surrounded by steep slopes, was also protected by an impressive fortification of the Murus Gallicus type, which completely surrounded the settlement. Two gates at each end provided access.

The main activity at Titelberg was the extraction and processing of iron ore and the production of iron tools and weapons. There was also production based on bronze and pottery, along with food production and animal husbandry. Titelberg was furthermore the main site for minting Treveri coins.

In addition to the residential and artisinal area, archaeologists have uncovered a dedicated space for Roman traders, and a large area referred to as Titelberg’s Public Space, dedicated to political and religious events, as well as occasional trading fairs, especially related to cattle.

Located at the intersection of important Gallic roads, Titelberg clearly held a prominent position in Treveri society; a proto-urban centre for its emerging economic aristocracy.

Following the Roman conquest of Gaul, Titelberg’s political role faded, especially following the relocation of Treveri aristocracy to the city of Trier (Augusta Treverorum), founded by the Romans around the year 17 BCE. Titelberg remained a vicus long into the Gallo-Roman era, but its fortifications were left to crumble, and its position as a political centre for the tribe came to an end.
