Murbach Abbey was a famous Benedictine monastery in a valley at the foot of the Grand Ballon in the Vosges. The monastery was founded in 727 by Eberhard, Count of Alsace, and established as a Benedictine house by Saint Pirmin. Its territory once comprised three towns and thirty villages. The buildings, including the abbey church, one of the earliest vaulted Romanesque structures, were laid waste in 1789 during the Revolution by the peasantry and the abbey was dissolved shortly afterwards.
Of the 12th-century Romanesque abbey church, dedicated to Saint Leodegar (St. Léger), only the transept remains with its two steeples, and the east end with the quire. The site of the nave now serves as a burial ground. The building is located on the Route Romane d'Alsace.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
