The medieval buildings of Ochsenhausen Monastery have not been preserved. In the portrait of the founders (1481, by Simon Rubner von Zweinbruck), two noblemen from the house of Wolfertschwenden hold a model of the medieval Monastery Church (Klosterkirche) in their hands. Here the simple hall architecture of the Late Gothic basilica with four windows each on the long sides can be clearly recognized.
The pulpit of the Ochsenhausen Monastery Church created by the Flemish sculptor Aegid Verhelst the Elder is a masterpiece of the Baroque period. Completed in 1742, the pulpit consists of a basket, which appears to be carried by an angel, and a sound-reflecting baldachin with a very elaborate design above it. On this baldachin stands Saint Benedict, who has been carried up to Heaven by angels. The entire work is characterized by its movement striving toward Heaven and its dynamic adornment.
In addition to the Chapter Hall (Kapitelsaal) and the Armarium (cabinet of technical instruments and apparatuses), the Library Hall (Bibliothekssaal), which was not erected in the north wing until 1783, is among the rooms realized in the style of early Classicism. Sixteen pillars support the choir, which is decorated by Ionic columns. The hall is done primarily in white and decorated with gods from classical antiquity (Hermes, Athena, Apollo) and a Muse (Urania). The ceiling frescos contrast these figures, which embody worldly knowledge, with divine wisdom.
