At the crest of the Káptalan Hill sits the fortified residence of Győr’s bishops, which has a mixture of Gothic, Renaissance and Baroque architecture.

At the core of the complex is the sturdy keep, with Gothic elements on its lower levels , built in the wake of the Mongol invasion in the 13th century, and a Baroque pediment and balustrade at the top.

Dating to the 15th century, the chapel connecting with east wall of the keep is a peculiar multi-level building.
