Choisy Cathedral, otherwise known as the Church of St. Louis and St. Nicholas, was the first cathedral of the diocese of Créteil, from 1966, when the diocese was created, to 1987, when the present Créteil Cathedral was inaugurated.
The church was built by the architect Ange-Jacques Gabriel under commission from Louis XV to provide a suitable place of worship for the court when the king was staying at his newly purchased residence at the Château de Choisy. The first stone was laid, by the king himself, on 4 July 1748, and the church was dedicated in the presence of the king, the court and the Archbishop of Paris on 21 September 1760.
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.
