The church of Liessies, which is dedicated to St Hiltrude, a miracle worker, has only a few fortification elements. Two towers embedded in the façade on either side of the portal and a few embrasures, that’s all.

A first church was built here around 1100 as part of Liessies Abbey, which was built in 751 and destroyed in 1791. After its destruction in 1541, it was completely rebuilt.

However, the inside is more interesting than the outside: a Byzantine copper cross decorated with precious stones and enamel, which probably dates back to the Crusades. There are also marble busts of Hiltrude and her brother Gontrad, wooden statues and a gilded bronze shrine. All these objects date from the 16th and 18th centuries. And as Sainte-Hiltrude is always open, you can also admire it from the inside.
