Pallozas, round houses in Galicia

Wonderful. Thank you, @mspath.

each palloza has two clearly distinguished areas inside: the ástrago, where people live; and the estravariza, the animal stable.

Using natural warmth from each other is an age-old solution to heating that we tend to look down on. But it works. Just think of how hot a crowded and closed albergue room can get. (Unfortunately it tends to come with odor. )
