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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
