The twin-peaked hill of Santiago Millas Curiosity · Santiago Millas, Astorga, León Image of Santiago Millas, not of the place itself. The place name, documented as Santiago de Mielles in 1334, is linked to the Latin gemellus, twin: the village is split between two quarters set on the two summits of one and the same hill, 955 and 938 metres high, separated by a track.
