Noves de Segre, Spain. In this small town with about 70 permanent residents and additional vacationers, single family homes are built several stories high on a small footprint. I am guessing that the compact size of these Pyreneese towns has to do with fortifications, land available for crops, and rocky soil which makes it very labour-intensive to build foundations. You can see a view out of our window and a view of the town from a little hill that I walked up early one morning - in the dark:-)
