The collection contains fragments of sculptures, carved architectural elements of artistic value, and fragments of tombstones from the period stretching from the 11th to the 16th century.

Late medieval wooden sculptures and panel paintings are to be found in two different exhibition spaces. While most of the winged altarpieces that are fully intact are displayed on the first floor, on the ground floor, single-piece works of art, including components of one-time winged altarpieces that now qualify as such, are in the majority. It is here that visitors can see the earliest pieces in the collection: works that date from the 14th century.
