Église Saint-Maurice (Church of Saint Maurice) is notable for its medieval tower and for being one of the earliest examples of Gothic Revival architecture in Alsace.
The church was first mentioned in 1165. The basis of the tower is Romanesque (late 12th-century). It is decorated with reliefs on the outside and with frescos on the inside. The upper part of the tower is Gothic and dates from the end of the 15th century. The rest of the church was rebuilt according to plans (1843, 1844) by the architect Charles Morin (1810–1897), and inaugurated in 1848. In 1888, the nave was covered with a wooden barrel vault.
The pipe organ is a 1762 work by Johann Andreas Silbermann. It was moved into this church from Old Saint Peter's Church, Strasbourg, in 1865.
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.
