League of God's House
About 1500 the abbey church was modified from a single-nave Carolingian construction into a three-nave late Gothic church. Shortly thereafter, in 1524 and 1526, through the Ilanzer Articles, the League of God's House was able to weaken the temporal power of the bishop, which had the indirect effect of reducing the income of the abbey. Consequently, there was limited construction on the abbey following this.
