The Three Viviers Nature Reserve

At this location, west of Sombreffe, there were originally three fishponds, fed by two tributaries of the Sombre (the Trois Viviers stream and another, unnamed one). These three fishponds were separated by a dike and ran alongside the path connecting Gentinnes to Ligny, which has recently been rerouted and re-stoned over a width of 3 meters thanks to the efforts of the "Sombreffe Trails" association. This same path spanned the Trois Viviers stream by a bridge made of a few large trees, which was repaired around 1795 using ash trees lying on the pond's dike. These bodies of water provided the population with fish living in the ponds (sticklebacks, carp), unlike the river fish (trout, salmon) found in the Orneau.In March 2023, a 3-hectare nature reserve was inaugurated on this site. You can observe birds, amphibians, insects, glaucous rushes, the fauna and flora of the pond... An observatory provides a beautiful view of the landscape of the Hesbaye Namur plateau.
