ABSTRACT
The Book of Donors is full memorial potential was only achieved when it functioned as part of a complex architectural and liturgical whole. Within the nave of the city's most elaborate Gothic edifice a distinctive chapel space was created in which the book was housed. This chapel of the Blessed Virgin, dedicated to the cathedral's patron, also contained the fabrica altar. The chapel apparently filled the space between the easternmost piers of the north nave arcade, adjacent, but not physically linked, to the choir screen of seven bays that divided the east end from the open nave below it. Bishop Conrad III von Liechtenberg was one of the cathedral's most ardent supporters. The bishop's tomb comprises a recessed and vaulted wall niche divided into three bays. Both the west end and the Chapel of the Blessed Virgin Mary were constructed as liturgical replacements for earlier structures.
