Lauriacum

The Legio II Italica built a legion camp around 200 AD, after the abandonment of an older site in Albin next to Virunum (In the area of today's Zollfeld at Maria Saal) and Ovilava (Wels) as administrative center for the Roman province of Noricum.

The legionary camp was subsequently also part of the fortifications of the limes and probably from the 3rd to the 5th century continuously occupied with Roman troops.

The best preserved ancient and early medieval testimonies are the remains of their predecessors accessible in the lower church of the today's Basilica of St. Lawrence.

After completion of the excavation work in 1966 St. Laurenz quickly received new attention: Lauriacum is a titular see of the Roman Catholic Church,[5] and the cathedra was centered in the district of Lorch in the city of Enns.

In the turmoil of the Migration Period, it was abandoned after the withdrawal of the Romans in 488, and was not replaced by the Bavarian and Hiberno-Scottish missions at the dioceses of Salzburg and Passau).
