The new Fayón by José Borobio Historical milestone · Fayón, Bajo Aragón-Caspe, Zaragoza Image of Fayón, not of the place itself. The opening of the Riba-roja reservoir in 1967 flooded the old quarter and made it necessary to build a new village, designed by the architect José Borobio. The population went from some one thousand six hundred households in 1960 to little more than six hundred ten years later. 1967 Photo: Josep Salvany i Blanch (Public domain) What to see and do in Fayón
