The Vathi’s mines at the Kroussia mountains

The subsoil of Kilkis holds a large number of mineral deposits. Some of the most important deposits are located in the village of Vathi and the surrounding area, known already in antiquity. The presence of copper deposits is indicated by the bright green and blue hues of rocks, caused by the copper minerals malachia and azurite in them.
The visible and easily accessible network of ancient mines in Vathi comprises a particularly interesting and alternative experience for the area’s visitor.
