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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
