The Cueva de los Cien Pilares is a large set of cavities excavated under the Cerro de San Miguel, in Arnedo, in the Cidacos Valley. It is not an isolated natural cave, but a cave complex formed by galleries and rooms connected to each other, with rock pillars that support the roof and explain the name of the place. Its origin dates back to the Middle Ages, when the population sought refuge and spaces for daily use in the rock. The visit allows you to see a unique subway landscape: carved rooms, corridors, areas interpreted as housing and spaces linked to religious and domestic uses. From the tour you can understand the relationship between the hill, the town center and the history of Arnedo, a town closely associated with the architecture carved into the rock. The complex is cited as one of the most intricate and striking of the valley, and is part of the Prehistoric Rock Art Trails. Its interest is not in a large natural room, but in the human footprint on the stone and how the habitat was adapted to the relief. The experience is done with a guided tour and usually requires prior reservation, so it is advisable to organize it in advance. It is a destination especially recommended in dry weather and good light, and is more comfortable outside rainy days, when the slopes and urban access are less pleasant.
