The Olimje castle is a symmetrical Renaissance building with four wings and impressive round towers. The Paulinian Order later found refuge in the castle, so a single-nave church of St. Mary's Ascension and a chapel of St. Francis were added. Monks converted the lower rooms of the western tower into one of the first pharmacies in this part of Europe.
