Palais des Princes-Evêques
This is outstanding. See the 16th century courtyard. The main facade is from the eighteenth century, and the west wing is later. It now houses the provincial courts and administrative offices. Prince Bishop Erard de la Marck was commissioned to give it its current appearance. It consists of two adjacent courtyards, only one of which is accessible. The 60 columns richly decorated with human figures with fantastic and grotesque masks, each is different. They are witness to currents humanist currents of Renaissance thought and the discovery of the New World.
