The ice well of Guardo Curiosity · Guardo, Alto Carrión, Palencia Image of Guardo, not of the place itself. A circular ice pit dug by hand and lined with stone, where snow was piled up alternating with layers of straw to supply ice to butchers' and fishmongers' shops all year round; ruined for decades, it was recovered by the Asociación de Entibadores Palentinos.
