Castilian towns are different than Galician ones (concentrated vs. scattered land occupancy). I could prove it along my route, and I could see it in situ when I arrived to Segovia.

Segovia is well-known because it has one of the most importan Roman aqueducts. But there are more treasures: Mozarabic architecture in the streets, the church where Isabel the Catholic was crowned, the late-gothic cathedral, and the wonderful Alcázar.
