What we know today as Camino de los Pilones was an old bridle path that connected the towns of Villarroya de los Pinares and Allepuz for about six kilometers.
Its main characteristic is the existence of large pylons built with masonry, stone and mortar. More than a hundred are preserved. They are cylindrical in shape, thickened and larger in diameter at the bottom and at the top. They are plastered on the outside and have a height of about 2.50 meters and a diameter of 0.65 meters.
They are placed at regular distances, approximately one every 30-50 meters, which signaled the path and guided the walkers, as they run along high hills, reaching over 1500 meters, with hardly any vegetation. With the blizzards, formerly so frequent, it was very easy to get lost or fall down a cut or ravine.
Pylons of similar size and shape to those of Villarroya and Allepuz have been found in the La Nava district and on the Pinar hill between Fortanete, Cantavieja and La Iglesuela del Cid. In the latter locality there is another section with pylons in the Puerto de las Cabrillas, in the direction of Portell. TThere are also some in the municipalities of Corbalán, Cedrillas and El Pobo. The route of the Camino de los Pilones as such is very old, we can affirm that it already existed in the Middle Ages, and it was probably the same one used by King Jaime I in his march from Teruel to Peñíscola.
