Graf-Lodronscher Primogenitur Palace

The Paris Lodron Primogeniture Palace, also known as the Old Borromäum, in Salzburg dates back to the primogeniture established by Paris Lodron in 1643.

In 1643, Prince-Archbishop Paris Lodron handed over to his brother Christoph von Lodron a part of the land gained by draining the Itzling and Schallmoss bogs within the city walls of Salzburg as part of the primogeniture fideicommissum. The Palatium Lodronicum also included what was later called the Old Borromäum, or the current building of the Mozarteum University in Dreifaltigkeitsgasse. The Primogeniture Palace itself was built by cathedral master builder Santino Solari.

During the city fire of 1818, this house also burned down, but it was largely restored. In 1846, Cardinal Schwarzenberg acquired the building, and in place of the previously existing low courtyard wing, the Borromäus Church was built here between 1846 and 1848. In 1849, the Collegium Borromäum, a Catholic private school named after the newly built church, was founded in the main house. It initially served primarily for the training of priestly candidates and later became a general gymnasium. This moved to Parsch in 1912, where it is still located today.

After that, the house temporarily served as a residence. From 1913, the newly founded Salzburg Marionette Theatre was also housed in the old gymnasium of the Old Borromäum. The Aicherpassage on the ground floor of the building still commemorates this today. In 1894, the city gate arch over Dreifaltigkeitsgasse (Mitterbachbogen) located at this house was demolished as a traffic obstruction. After the Second World War, the offices of the bombed-out Museum Carolino Augusteum were located here.
