The Baroque building with a U-shape plan on the Main Square was originally a seminary. IIn 1785, Bishop Christoph Anton Migazzi gave the building to the Sisters who turned it into a hospital.

There is a Baroque chapel in the building where there are regular masses. Its thin ridge turret can be easily spotted from the square. The altarpiece of its side altar depicts the founder of the order, John of God, and the main altarpiece depicts Charles Borromeo, archbishop of Milan.
