The Old Hospital was presumably built around 1200. The oldest remaining cores are two arms of the convent corridor from 1636 and the wings connected to it, including the bishop's hall from 1644-1647.
The current little hospital church dates from 1761-1763 and is designed in Louis XV style. In the outer courtyard next to the church is the old pinnacle of the original Marbol fountain, the source on the market square.
