The architect Johann Jakob Herkomer (1652-1717) succeeded in turning the irregular medieval abbey premises into a symmetrically organised complex of buildings. The transformation of the medieval basilica into a Baroque church based on Venetian models was intended to be an architectural symbol of the veneration of Saint Magnus. The entire church represents an enormous reliquary. For the first time in South German Baroque construction the legend of the local saint inspires the suite of frescoes throughout the entire church. The community at the time also set out to make the new church the envy of connoisseurs for the quality of its artworks. Among the artists who contributed various forms of decoration for the building were Anton Sturm, Franz Georg Hermann, Jakob Hiebeler and Paul Zeiller, whose only extant oil paintings are in the Chapter Hall.
