Church of Our Lady of the Assumption (Olloy-sur-Viroin)

Highlight • Religious Site

Olloy-sur-Viroin is a town and submunicipality of the Belgian municipality of Viroinval. Olloy-sur-Viroin is located in the province of Namur. The Église Notre-Dame de l'Assomption, parish church in neo-Gothic style, built in the nineteenth century.
The building was restored at the beginning of the twentieth century.
The building has three naves, a non-projecting transept and a square choir. The tower is independent of the rest. We had the impression of discovering a belfry.

Fondry des Chiens Gorge

Highlight • Gorge

Near the town of Nismes, the Viroin-Hermeton Nature Park is home to an exceptional nature reserve. A narrow gorge, up to 20 meters deep, is home to a biotope rich in biodiversity. This gorge was formed over millions of years by rainwater erosion. The particular soil conditions created a ravine with large boulders. The "Fondry des Chiens" is a nature reserve and is considered a natural monument. The trail to the top can be quite technical, but the difficult sections are actually short.

Through the depths hollowed out in the limestone, you reach the Roche aux Faucons (the falcon rock) and the viewpoint over the village of Olloy-sur-Viroin, the Viroin valley, the wooded hills, a quarry and the railway where the "steam train of the 3 valleys" occasionally passes. In the distance, the hilly landscape of the Kalkzoom changes into the Ardennes forests.
