Above the cemetery, catacombs cut directly into the rock face of the Festungsberg. They may date to the Early Christian era - the time of Severinus of Noricum, the Roman-era saint who ministered to the people of the Danube frontier during the Migration Period, when the Roman Empire's western provinces were dissolving. Whether these cavities served as hermit cells, refuges, or burial chambers in those early centuries remains debated, but by the medieval period they held two consecrated chapels. The Maximuskapelle and the Gertraudenkapelle were dedicated in 1178 under Archbishop Conrad of Wittelsbach, and their patron is striking: Thomas Becket, the Archbishop of Canterbury murdered in his own cathedral eight years earlier. That a Salzburg archbishop would honor an English churchman killed for defying his king speaks to the politics of the medieval church - clerics recognized their own, and Becket's martyrdom resonated across every archbishopric in Europe.

The adjacent St. Peter's Abbey was established around 700 by Saint Rupert of Salzburg, and the cemetery grew alongside it, likely on the site of an even older burial place. The oldest surviving tombstone dates to 1288, and the first written mention of the cemetery appears in an 1139 deed. A second chapel, the Margarethenkapelle, was rebuilt in 1491 and occupies a central position among the graves. In 1878, the cemetery was closed. For half a century, the grounds deteriorated - ivy overtook markers, iron rusted, stone crumbled. Then in 1930, the monks of St. Peter's successfully petitioned for the admission of new burials, and the cemetery returned to life. That reopening preserved the Petersfriedhof as a working burial ground rather than a museum piece, and new graves continue to appear among headstones that predate Columbus.

The names on the stones read like a cultural register of the city. Santino Solari, the architect who designed the current Salzburg Cathedral, was buried here in 1646. Heinrich Ignaz Franz Biber, one of the great Baroque violin composers, followed in 1704. Maria Anna Mozart - Nannerl, Wolfgang's gifted elder sister who was denied the performing career her brother enjoyed because of her sex - was laid to rest here in 1829. Michael Haydn, Joseph Haydn's younger brother and a distinguished composer in his own right, was buried in 1806. In the 20th century, the cemetery received Franz Wasner, who guided the Von Trapp family's musical life before and after their famous escape from Austria, and Clemens Holzmeister, the architect who designed the Salzburg Festival's performance spaces. Even a U.S. Army major general, Harry J. Collins, rests here - buried in 1963, far from America but in a place that takes its dead seriously.

What sets the Petersfriedhof apart from many European cemeteries is its intimacy. There are no grand mausoleums or sweeping avenues of tombs. The graves cluster close together beneath the cliff face, shaded by the Festungsberg and overlooked by Hohensalzburg Fortress hundreds of meters above. Wrought-iron lanterns mark individual plots. Seasonal flowers are refreshed by the families and by the monks of St. Peter's who still maintain the grounds. Visitors walk paths barely a meter wide between headstones that span seven centuries, with the rock-cut catacombs looming above and the sounds of the old town - church bells, street musicians, the murmur of the Salzach - drifting over the cemetery wall. It is one of Salzburg's most visited tourist attractions, but it remains, fundamentally, a place where the city buries its own.
