The Petersfriedhof or St. Peter's Cemetery is - together with the burial site at Nonnberg Abbey - the oldest cemetery in Salzburg. It is one of Salzburg's most popular tourist attractions. Its origins date back to about 700, when the adjacent St. Peter's Abbey was established by Saint Rupert of Salzburg. The abbey's cemetery, probably at the site of an even earlier burial place, was first mentioned in an 1139 deed, the oldest tombstone dates to 1288. Closed in 1878, the site decayed until in 1930 the monks of St. Peter's successfully urged for the admission of new burials.
Carved into the rock of the Festungsberg there are catacombs that may stem from the Early Christian days of Severinus of Noricum during the Migration Period. They include two chapels: The Maximuskapelle and the Gertraudenkapelle, consecrated in 1178 under the Salzburg Archbishop Conrad of Wittelsbach and dedicated to the assassinated Archbishop Thomas Becket of Canterbury.
A second chapel, The Margarethenkapelle, (re-)built in 1491, occupies a cite in the center of the cemetery.
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.
