A number of the monastic buildings are still extant. In particular, the former abbey church survives as the parish church of
Saints Peter and
Paul. The original buildings were from around 880. The abbey was entirely rebuilt in the first half of the 11th century. When
Pope Saint Leo IX passed through Andlau in November of that year he was able to translate the remains of the canonised Richardis from the old church to the new
Romanesque one. Nothing remains of the first buildings (except for a hole in the floor of the
crypt said to have been made by the she-bear). The crypt itself dates from the 11th century. Another major re-construction took place in the 12th century after a serious fire, and another in the 15th century. The nave was completely rebuilt in the late 17th century. The present tomb of Saint Richardis dates from 1350, and is sited in a
Baroque chapel of 1707. The church is however most notable for its rich
sculptural decoration, by the
Master of Andlau, which is among the finest in Alsace. It is located on the ''
Route Romane d'Alsace''. ==Burials==
