Hórreo: If you pronounce this word like OREO you are pretty close. Hórreos are commonplace in northern Spain, from the smallest of hamlets to the largest of private estates. They vary in design from region to region and in Galicia they tend to stretch out lengthwise. They function as corn-cribs, with slatted walls that allow for circulation and a foundation designed to prevent rodents from climbing up. They range in length from 2m to 35m.
