En uno de sus valles recorrido por el río Iregua, está el Camero Nuevo, tierra de bosques, pastizales, cumbres y pequeños valles, donde se sitúan 13 pueblos con historia, tradiciones y leyendas, que siglos atrás se agruparon bajo la denominación de Hermandad de las 13 Villas.
This small spot located on the González Lacasa Reservoir is the village of Nieva. It has beautiful samples of traditional Camerano architecture and a parish devoted to Nª Sra. de la Visitación. Inside, an image of the Virgin and Child in alabaster with a dedication dated 1798, although it is a XVI century work.
In the surroundings, in the Cerro de Castejoncillo, archaeological remains from the Bronze Age and with occupation until the Roman era were traced. Nearby is the Chapel of Saint Julian, where tradition says there was a village, as evidenced by the site that is near the Roman Road of Iregua, which runs through the region.
