The Arcaded Galleries

The galleries form two levels of passages linking the castle's four wings. The lower arcades rest on granite piers, while those above have more slender limestone supports. The octagonal shafts of the upper columns meet square bases and capitals. Both the materials and proportions change between the two levels.

Vaults cover the passages, with a different arrangement at the corners. Originally, the galleries had chamfered corners; after a fifteenth-century fire, these were rebuilt as right angles. The present circuit around the courtyard retains its medieval structure, though not every part survives in its earliest form.

The walls preserve a cycle of paintings dating from around 1380–1400. Figurative scenes are accompanied by painted architectural divisions and ornament. The decoration reflects the influence of Bohemian art, probably associated with Bishop Henryk Sorbom's contacts with Prague: he had previously been secretary to Emperor Charles IV.

Conservators left the losses in the old paintings visible. Reconstructions of their complete appearance were presented on separate panels, rather than painted over the originals. This separation makes it possible to compare the surviving medieval paint with the reconstructed composition and identify the fragments preserved through the centuries.
