Horreos

Paradela- near Portomarin.
Horreos- I think the first documented mention of an horreo was in the 1500s.

An hórreo is a typical granary from the northwest of the Iberian Peninsula, built in wood or stone, raised from the ground by pillars ending in flat staddle stones to prevent access by rodents. Ventilation is allowed by the slits in its walls. Wikipedia
