Despite their high level of activity, and not withstanding the problems which the Dominicans encountered from secular clergy and the City alike, from around 1307 or 1308, they began extending their church. By 1317 the construction had reached the fifth pillar of the nave. A new consecration ceremony was held on the 17th September 1345, on the occasion of a General Chapter presided by Berthold de Buchegg, Bishop of Salzburg. We do not know what changes or additions were made to the windows, but the new choir had six bays instead of the previous three, and the double nave, which made this a veritable " Hallenkirche ". It boasted ten lit bays, with as many high bays to the South, and lower bays to the North, which backed on to the cloisters. We can be certain that the window panels from the first church were incorporated, if only partially, into the new one.
