The presented artefacts come from the second half of the 13th century (from the chapel and refectory) and from the first quarter of the 14th century (from the chapter house and cloisters). Some of the exhibits obtained through archaeological research can be dated to the 15th century. The most frequently used decorative and sculptural material was clay, which could be modeled or carved. It was cut out with the use of matrices and templates, and sometimes, as in the case of floor tiles, only stamped. Shaped elements were burned and often polychromed or painted.
These decorative ceramic forms exemplify early architectural sculpture in medieval Prussia. Small elements were sometimes made of natural stone. Artificial stone, or extremely durable screed gypsum, was also used, usually using a mold-casting technique. It was an important sculptural material used in the monastic state, both in architectural decoration and in monumental sculpture.
