The village was built on an imposing rocky spur that emerged from the sea millions of years ago as a result of tectonic uplift. Located at the centre of a large territorial area about 15 kilometres in diameter, the spur can be seen from every direction. Characterized by natural steps and man-made terraces, the surrounding landscape is an embroidery which is partly natural – with its clayey and tuffaceous shades – and partly man-made – with crops, olive groves and vineyards from which Designation of Origin (Denominazione di Origine or DO) products are produced with indication of the geographical name. This bond with the landscape has helped to create a strong union between agricultural products and the territory of origin.
The public park contains many examples of century-old plants and hosts the most traditional events of the ancient village: the Homemade Lasagna Festival, and the Festival of Craft Beer and other products from the local area. Montenero was one of the first castles to be built on the western side of Monte Amiata, of which unfortunately only a few traces found inside the park are still visible.
