Architectural style of 17th-18th centuries in Prince-Bishopric of Liège
Mosan Renaissance also known, at least in French, as the Mosan style,[1] is a regional architectural style dating from the 16th to 18th centuries. The style is related to Renaissance architecture, but with very limited classical influence; it has been described as "voluntarily anachronistic".[2] The term should not be confused with Mosan art, which applies to Romanesque art and architecture during the Middle Ages in the region of the Meuse river valley.
The Mosan style developed in the Prince-Bishopric of Liège in the 16th century during the reign of Prince-bishopÉrard de La Marck (r. 1506-1538). The style is an adaptation of earlier vernacular methods of timber framing, but using stone instead of wood. 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. Where there are columns, mostly in arcades, the capitals are usually very simple. In grander buildings, the interiors may included vaulted halls, and the exteriors "square pavilions topped with ornate roof spires, cross windows and cornices".[3] In general the decoration on exterior walls projects very little, but on roofs there may be projecting ornament in various forms.
