The baroque landmark of Linz made of white Salzburg marble is 20 m high and was built between 1717 and 1723. The execution was in the hands of Salzburg stonemason Sebastian Stumpfegger after a design by Antonio Beduzzi. On the pillar, three inscription panels with the imperial coat of arms, the coat of arms and the coat of arms of the city of Linz represent the dedication by the emperor, the estates and the people of Linz. They had the pillar built out of gratitude for rescue from the threat of war (1704), fire (1712) and plague (1713). On the pedestal are the statues of the plague saints, St. Sebastian and St. Karl Borromäus, as well as the fire patron saint, the hl. Florian, attached. The column is adorned with a statue of Maria Immaculata. The crowning trinity group is made of gilded copper.
Until 1716, the pillory was located on the main square of Linz, which was relocated to the pigeon market due to the planned construction of the Holy Trinity Column. The great flood in 1872 penetrated to the Trinity Column. During the Second World War from 1943 all decorative elements were removed and the coats of arms embedded in plaster for protection. After the end of the war, the column was completed again until December 1947. [
