Caves and potholes in Artesa de Segre

Artesa de Segre, in la Noguera, sits on the bank of the river Segre, at a point where the Lleida plain begins to give way to the foothills of Montsec and the Pre-Pyrenees. A town of some regional weight, its municipal district stretches toward more rugged, limestone relief to the north, where the catalogue of cavities finds its natural context.
