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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
