Town Hall of Fayón Monument · Fayón, Bajo Aragón-Caspe, Zaragoza Image of Fayón, not of the place itself. The present-day town hall of Fayón is part of the new village designed by the architect José Borobio after the embalse de Ribarroja flooded the old town in 1967; the population went from about sixteen hundred households in 1960 to just over six hundred ten years later.
