I passed through there a long time ago and it wasn't lit, which scared the young children present. This tunnel is quite long, without lighting in the middle it's really dark. However, I have seen photos where lighting can be seen. It's a good thing if it is well maintained and lit 24/7.

Ruins of Montaigle © Aurélie Ducroze Montaigle, an exceptional monumental site in Wallonia, is situated on a rocky spur in a romantic setting whose magic transports you back to the time of the knights. A visit to the ruins of this imposing fortress, once a count's residence (14th century), and to the archaeological museum will open a window onto an extraordinarily rich medieval world. In the 100 m² museum, the history of the site and the monument is told through a thematic and chronological exhibition of objects discovered on site (crossbow bolts, cannonballs, tools, pieces of crockery, medals, coins, stained glass, paving stones, slates, jewelry, etc.). The architecture of the fortress and the challenges of saving a threatened monument are also discussed.

Charles Radoux-Rogier, born in Ougrée on February 22, 1939, died in Gérin (near Florennes) on February 9, 1968. Charles Radoux-Rogier began his training with the 147th Class of Student Pilots on May 8, 1961 and received his wings on February 16, 1963. At the time of his accident, Lieutenant Radoux-Rogier was flying with the 2nd Squadron of the 2nd Wing in Florennes. On February 9, 1968, his F-84F FU138 crashed in Gerin shortly after takeoff from Florennes. The cause of the accident varies according to sources: according to the book "The Broken Wings of Belgian Aviation", he suffered a collapse shortly after takeoff, while another source suggests a technical problem. A cross stands at the crash site in honor of Lieutenant Radoux-Rogier. Info: Frédéric Delizée, October 10, 2012 via https://www.hangarflying.eu/
