If you have time to visit only one fortified town, this should be it. From the moment you walk through Sortelha’s massive ancient stone walls, you feel as if you're experiencing a time warp. Except for a few TV antennas, there's little to evoke the 21st century. The streets aren't littered with souvenir stands, nor is there a fast-food outlet in sight. Stone houses are built into the rocky terrain and arranged within the walls roughly in the shape of an amphitheater.
