Bridge of los veinte ojos Monument · Villamañán, Esla-Campos, León Image of Villamañán, not of the place itself. A brick bridge on the old N-630 road known for the number of its arches. It is an uncommon example of a public work built with the same fired clay as the houses and cellars of the comarca. Photo: César Pérez García (CC BY 2.5) What to see and do in Villamañán
