When we left Fisterra, we white-roaded our way back so we could drive through the twin towns of Lira & Carnota. I wanted to see the dualing Horreos.
Horreos are unusual and unique in Spain to Galicia. They are graineries made of stone and stand on stilts to keep rats from getting to the stores. The design has unusual louvered slats (also of stone) that allow air to circulate but keep rain out. Every home has its own horreo.
In many areas the size of the horreo was an indication of your prosperity. A family with an 8 ft long horreo was middle class.
the reason the two towns of Lira & Canota have these ridiculously long 35 foot horreos was because the two bishops in these towns were in competition. The horreos are both in the churchyards.
Horreos are a source of exteme regional pride in Galicia. I don't know if there is legislation to protect them, or if their protection is through cultural tradition. But, as you can tell from the picture below, Galicians go to great lengths to preserve the Horreo.
