Salzburg begins restoration of historic Bürgermeisterloch wall opening

Restoration has begun on the historic fortifications west of Salzburg Fortress at the Bürgermeisterloch, a passage cut through the wall. The section is expected to cost around 1.3 million euros, ORF reported.

The five sections of the defensive wall on the Mönchsberg formed part of the city’s historic military fortifications, known as the Schartenwall, built during the Thirty Years’ War. They were intended to secure the narrow point between the Mönchsberg and the fortress hill.

The 17th-century masonry must be repaired and reinforced to prevent rock and other material from breaking away. Workers are repairing the top of the wall and renewing the mortar between the stonework. They will also remove vegetation, improve protection against moisture and anchor loose stones with steel rods.

Archaeologists are accompanying the work, which is being carried out stone by stone to ensure that historical remains are not overlooked or damaged. Materials that are as authentic as possible, including conglomerate stone, are being used.

The opening was first documented in 1867. More than 200 years after the fortifications were built under Prince Archbishop Paris Lodron in the 1630s, the wall was breached on the orders of Salzburg mayor Heinrich Ritter von Mertens. As a resident of Brunnhausgasse, he used the passage beneath the arch on his daily walk to work at city hall, leading Salzburg residents to nickname it the Bürgermeisterloch.

The restoration is scheduled to continue until autumn 2027.
