All Saints' Church is a chapel located in the Prague Castle complex. The site of the church was originally consecrated in 1185 and a Romanesque building built; the oldest parts of the current building date to a structure constructed by Peter Parler in the 14th century.
Although originally free-standing, the church was badly damaged in an 1541 fire which engulfed the palace and church. Through subsequent successive rebuildings and enlargements, the church became physically integrated with the palace, specifically Vladislav Hall.
The church holds the tomb of St. Procopius and his life is depicted on paintings on the walls. Although accessible from Vladislav Hall, the church is generally only open to the public during religious services and concerts.
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.
