In the crypt underneath the choir a few remnants of the 11th century (Romanesque) building can still be seen.

Saint-Hubert is a municipality of Belgium. It lies in the country's Luxembourg Province (Walloon region). The town is named in commemoration of Saint Hubert, whose thighbones were moved in 825 to the Benedictine Abbey of Andage (Andagium), thereafter called Abbey of Saint-Hubert. Saint Hubertus or Hubert (died 727) called the "Apostle of the Ardennes" was the first Bishop of Liège. The church became a focus of pilgrimage after the translation of his bones in 825. The interior is Late Gothic.
