reform of Hirsau
Originated with the Benedictine abbey of Hirsau (Baden-Wurttemberg, W. Germany). Finished in 1065, this then became the center of a school of architects who evolved new shapes for Romanesque churches, better suited to the Gregorian liturgy, which they were championing (“greater choir” for the singers, “lesser choir” for the non-singers, both usually before the crossing; no apse; and towers forming part of the facade). The new ideas spread through central and southern Germany in the tenth and eleventh centuries. (Pothorn, 1979)
