Andlau Abbey was a women's collegiate foundation for secular canonesses located at Andlau in Alsace. Andlau Abbey was founded in or about 880 by Richardis, later Saint Richardis, empress of Charles the Fat, on her ancestral lands. The abbey survived the Reformation, thanks to the efforts of the Abbess Rebstock, who is commemorated in the present church, but not the French Revolution.
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 Leo XI 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.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
