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.
Crossing the bridge we reach the neighbourhood of Barruelo, whose cobbled square and fountain are of a simple beauty.
The ruins of the church devoted to the Virgin of Las Vegas, from the XVI century, are preserved in its highest part, where there is a beautiful sacristy. A few meters away, following the space occupied by the old threshing floors, we find the chapel of Saint Andrew, in a primitive Romanesque style with a round apse, which was declared a National Artistic Historical Monument in 1981.
