The most famous representative of the dynasty, Godfrey of Bouillon (Duke of Lower Lorraine, c. 1060 to 1100), takes us back in time to the late 11th century. Geographically, however, the life story of this man takes us far from his homeland: across the Mediterranean to the Holy Land. He participated as a leading figure in the First Crusade and the conquest of Jerusalem. After the city's capture, he was to become king of the Crusader Kingdom of Jerusalem, but he rejected such a title, arguing that the only king over Jerusalem could be Christ himself, who was crucified and buried here—and resurrected.

This beautiful suspension bridge is 55 meters long and is located at the intersection of several hiking trails. The Moulin de l’Épine footbridge was built to connect hikes from Botassart and Corbion. The bridge only opened in 2020 after years of legal wrangling. A wooden watchtower stands on both banks of the Semois River. The Moulin de l’Épine footbridge consists of 22 galvanized steel elements with wooden planks held up by two strong cables. The bridge wobbles and sways quite a bit when hikers walk across it, but is otherwise as safe as can be. (TravelValley)

The fortified castle of Bouillon is situated on three rocky ridges and offers stunning views of the city. During your visit, you can also take in a falconry performance. Falconry was a true art form during the Middle Ages. You can conclude your visit with the Scriptura Museum, which chronicles the history of education, and the exhibition of the fresco "The Armed Pilgrimage of Godfrey of Bouillon." The castle is open daily.

When we were there (early June) the view was largely obstructed by the bushes… a shame, but it remains a beautiful spot.
