Mosan Renaissance architecture

The Mosan style developed in the Prince-Bishopric of Liège in the 16th century during the reign of Prince-bishop Érard de La Marck (r. 1506-1538).

Stone-framed rectangular windows, round-arched doorways and sometimes decorated architraves, all on walls of brick, are characteristic of the style.

Stone window frames, mullions and courses, contrasting in colour with the red brick background, create strong patterns on the exteriors.

Plain stone squares may be added to fill out the pattern; in some buildings like the merchant's mansion that is now the Curtius Museum these carry reliefs of a single animal or head.

In grander buildings, the interiors may included vaulted halls, and the exteriors "square pavilions topped with ornate roof spires, cross windows and cornices".
