Recently brought to light and made understandable to the layman, the remains of the C11th abbey church are indicated on the list of the 159 properties of the outstanding heritage of Wallonia.

The key building period corresponds to the reign of the abbot Poppon. The plan of that period essentially continued to serve its dual purpose as a monastic church and a church of pilgrimage until the end of C18th. Preceded by an imposing tower restored in 1534, but of which only the ground floor, measuring 15 m high, remains, the nave (partly excavated) leads to the monks’ chancel and to the chancel reconstructed through archaeological research.

After having visited the Museum of the Principality and having virtually entered the abbey church using the latest 3-D technologies, the visitor can really stroll from the transept to the chancel, from the nave to the crypt to feel the imposing presence of the walls, which disappeared after the French Revolution.
