The baptismal font at St Bartholomew's Church, Liège is a Romanesque brass or bronze baptismal font made between 1107 and 1118 now in St Bartholomew's Church, Liège in Liège, Belgium. The font is a major masterpiece of Mosan art, remarkable for the classicism of its style, whose origin has been the subject of great debate among art historians. The Meuse river valley in modern Belgium and France, roughly coterminous with the Diocese of Liège, was the leading 12th-century centre of Romanesque metalwork, which was still the most prestigious medium in art.
