Liège Cathedral, otherwise St. Paul's Cathedral, Liège, is the seat of the Diocese of Liège. During the French Revolution the ancient cathedral of Liège, St. Lambert's Cathedral, was destroyed systematically, from 1794 onwards. After the revolutionary fervour had evaporated a new cathedral was needed. The ancient collegiate church of St. Paul's was thought suitable for the purpose and was elevated in rank, before 1812. This is the present Liège Cathedral.
