7th - 12th century

The settling Bayuvarians preferred the left side of the Traun where it met the Danube for their settlement, and two burial sites from the second half of the 7th century have been uncovered at the present VOEST-Alpine site, bearing witness to the multiple cultural relations to the East (Byzantium) and the South (Italian-Lombards).

The settlement at the crossing over the Danube gained in significance as the Duchy of Bavaria expanded its power eastwards across the river Enns in the 8th century.

The first documentary mention of Linz occurred in 799, when Count Gerold, Prefect of the Ostland and brother-in-law of Charlemagne received tenure of the St. Martins Church with its ‘castrum’ (fortified settlement) in the ‘Locus Linze’ for his lifetime from Bishop Waltrich of Passau.

During the reign of the Carolingans Linz was the central settlement of the Traun province with a market and customs, as entered in the Customs Book of Raffelstetten (903-905).

Presumably around 1000 A.D. the focal point of the settlement was transferred from the ‘castrum’ to the west of St. Martin’s Church at the foot of the castle hill to the terrace around the Old Market, which was safer from flooding. A Jewish community was concentrated around the Old Market in the pre-Babenberg period.

985/991
Bishop Pilgrim of Passau has the tithe of the Baptist Church in Linz fixed.

903/905
Entered in the Customs Book of Raffelstetten as a royal market with a customs seat.

9th century
Rebuilding of St. Martin’s Church in the style of a representative Carolingan central construction, which was probably destroyed in the 10th century.

799
First documentary evidence of the "locus Linze", St. Martin's Church on the castle mount plateau and a defensive enclosure (castrum), whose location is thought not to coincide with the site of the subsequent Linz Castle. Waltrich, Bishop of Passau, awards St. Martin's Church to Gerold, Prefect of the East Lands and brother-in-law of Charlemagne, to own during his lifetime in return for payment of interest. The church had previously been the property of the royal chaplain Rodland.

7th century
Construction of two fields of Bavarian row graves on the northern bank of the Traun where it enters the  Danube, now the location of the VOEST-Alpine (formerly Linz Zizlau), south east of late classical Lentia.
