Guilhou family Protestant cemetery Curiosity · Mieres, Caudal, Asturias Image of Mieres, not of the place itself. A burial ground built between 1860 and 1880 by the French industrialist Numa Guilhou, founder of the Fábrica de Mieres, to bury the foreign families who came with industrialisation. It is the only Calvinist Protestant cemetery in Asturias and Guilhou himself lies there. Photo: José Antonio Gil Martínez from Vigo, Spain (CC BY 2.0) What to see and do in Mieres
