The Grand Curtius occupies one of the most remarkable buildings in Liège — the 17th-century mansion of patrician Jean de Corte, known by his Latin name Curtius. Together with the nearby Musée d'Ansembourg, its collection offers a sweeping overview of archaeology and decorative arts in the Liège region from Gallo-Roman times through the Middle Ages to the 18th century.
Highlights include the gospel book of Bishop Notger (ivory and enamel, 10th and 12th century) and a Madonna attributed to Dom Rupert. The museum also holds coins, seals and medals from the old Prince-Bishopric of Liège.
