Galician horreos
Galician granaries (hórreos) are one of the most emblematic architectural symbols of Galicia and a very special cultural expression within the European context. These elevated structures, abundant in this region of Spain, originated from the need to protect food from ground moisture and animals that infested agricultural areas. Over the centuries, they have become not only a functional resource but also an essential part of the cultural, ethnographic, and landscape heritage for understanding the history of rural life.
What are Galician horreos? Origin and function of the granaries
The term hórreo comes from the Latin word horreum, which means “storehouse” or place for storing grain. Its main function was to store agricultural products such as corn, wheat, chestnuts, or rye, keeping them dry and well-ventilated.
Built predominantly of wood and granite stone, Galician granaries are characterized by being raised on columns, called pegollos in Galicia, which end in circular pieces called tornarratos or vira-ratos, specifically designed to prevent rodents from climbing to the stored food.
The elevated structure, besides facilitating ventilation, protects the contents from ground moisture, a major challenge in a region as rainy as Galicia. Thanks to this highly effective design, hórreos have not only endured for centuries but have also been copied in various parts of the world where Galician emigrants settled, especially in Latin America.

Morphology and typology
Although all Galician horreos share the purpose of preserving food, their design varies considerably depending on the region of Galicia. The most obvious differences are seen in the shape of the roof, the supporting stones, and the overall structure.
On the coast, for example, long granaries with slate roofs and large side windows, designed to take advantage of the breeze for ventilation, are common. Inland, some models are more compact and robust, adapted to rainier climates. Stone and wood are the predominant materials, although in certain areas only one of these two materials is used in the structure. This varies considerably from region to region.

The granary of Carnota: the longest in Spain
Among all the Galician granaries, one stands out: the Carnota granary. Located in the town of Carnota, in the province of A Coruña, it is renowned for being the longest in Galicia, measuring over 32 meters. Its monumental size is striking not only for its dimensions but also for the remarkable preservation it has enjoyed over the years.
The granary of Carnota rises on 32 pairs of stone columns and is topped with a seemingly endless roof of local tiles. This length reflects the agricultural importance of the area in times past, when considerable space was needed to store the harvests produced to sustain the local parish.
This example is a clear testament to Galician architectural tradition, a tangible demonstration of how the rural community used available resources—stone, wood, and clay—to build efficient, durable infrastructure that harmonized with the environment. Today, it is considered a monument that attracts many tourists each year.
Heritage and conservation
For years, hórreos (traditional Galician granaries) have gained formal recognition as part of Galicia’s cultural heritage. Many of these structures have been restored and protected by public institutions and cultural organizations in order to preserve this ethnographic legacy.
Heritage protection regulations have helped many Galician granaries, which were in danger of disappearing due to rural abandonment, not only to be saved, but also to be admired by Galicians themselves and by visitors from other places.
A symbol of identity
Beyond their original function, Galician granaries represent an essential part of Galician identity. Their silhouette against the green landscapes, their natural materials, and their presence in small villages and on rural hillsides evoke a way of life that has profoundly shaped the history of Galicia.
In popular culture, hórreos appear in photographs, postcards, travel books, and works of art, reflecting the aesthetic power of simplicity and functionality. They have become an emblem not only of Galicia, but of Spain as a whole.
