Hórreos of Prioro Curiosity · Prioro, La Montaña de Riaño, León The village preserves wooden hórreos with tiled roofs pitched on two or four sides, the solution used to keep grain out of reach of damp and rodents at the eastern end of the León mountains. Fifteen examples remain, thirteen in good condition, against the sixty-nine that stood in the 18th century; they were declared a Monumento Histórico (historic monument, a Spanish heritage-protection designation) in 1979. Most are of the Asturian type, quadrangular structures raised on four oak posts that isolate them from damp and rodents, with no nails or permanent fixings, so that they could be dismantled and moved. In front of several of them a large carved-log staircase is preserved that does not reach the door, to keep rodents out. Photo: Uviein (CC BY-SA 4.0) What to see and do in Prioro
