Hórreos are traditional granaries found primarily in the northwest region of Spain, particularly in Galicia. These structures are elevated on stone or wooden pillars, which helps protect stored grains from moisture and pests. Typically made of wood or stone, hórreos feature a distinctive design with a gabled roof and slatted walls for ventilation. The construction of hórreos dates back to the Middle Ages, reflecting the agricultural practices of the time. They are often decorated with intricate carvings and serve as a symbol of rural heritage. Today, many hórreos are preserved as cultural landmarks, showcasing the region's history and architectural style.
