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:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
