CAVING IN BELGIUM: THE BELGIAN CAVE GUIDE
Trou de l'Eglise - Mont-sur-Meuse (No. 07)


 

LOCATION:
Province: Namur
Locality:  Mont-sur-Meuse (Yvoir)
Coordinates:  187.904 / 115.953 / 199.24 m
Map: 53/4
Take direction Mont-sur-Meuse, coming from the river "Meuse".  Enter the village and stop at the church.  The cave is in a large sinkhole, opposite to the church.

HISTORY:
Salle de la Cathédrale (picture by Paul De Bie)The cave was discovered by Bernard Magos, after digging out the entrance, in 1950. First exploration by a team of the U.L.B.  Since then, many teams have tried their luck in this cave but really big discoveries were never made again. However, some significant continuations were found (e.g. Réseau du Cimétière) but the authors remain unknown.

ACCESS:
Originally the cave has two entrances, but one collapsed in the 80's.  The entrance that one takes nowadays is a narrow slot in which the (tiny) river disappears.  A heavy steel door, with a U.B.S. lock, closes the cave.  Contact the Belgian Caving Federations to obtain the key.

DESCRIPTION:
Length: 1065 m,  Depth: 78 m
Originally this was one of the most decorated caves in the country!  However, this easy cave was quickly used a "school cave" and suffered (and still does!) from the huge quantities of visitors.
Nevertheless, it stays an interesting and varied cave.  At the foot of the entrance pitch, several ways lead to the impressive (2 m wide and 15 m high) stream passage at the foot of "the waterfalls".  After 50 m metres, possibility to climb up to the well decorated "Salle des Gours" (6-m. climb).  Another 50 m. further on, the river disappears in a few narrow slots.  One can continue in a fossil 2-level gallery, in West-direction, until this ends. When taking the upper level to come back, one easily finds the way to another part of the cave "Réseau du Babydoll", going East. Here another river, coming from Trou Dury, enters the cave.  The farthest point of this gallery is only 50 m away from Trou Dury.  In the Babydoll, one can admire the most beautiful fossil coral reefs to be seen in any Belgian cave!Giant fossil coral reefs in the Babydoll (Picture by Paul De Bie)
 

RIGGING:
The entrance pitch, 7 m deep, is rigged with a fixed steel ladder.  You don't need any ropes to visit the rest of the cave.  However, a 15 m rope could be of use since some climbs could be a bit difficult for unexperienced cavers (e.g. climbing up to "Salle des Gours")

COMMENT:
In wet conditions, climbing up the waterfalls is an absolute must!


IMPORTANT: this cave is situated in the middle of the village and besides a church and graveyard.  Please do not park the cars in front of the church.  Be discrete: no strip-teasing and no loud noise please!
