We took a wrong turn on the road to Ronda, Spain. We went through a cave / house street in Setinel, Spain. About 3 inches on each side of the car, which turned into a tunnel with houses on one side. People walking through. Could not figure out how to escape. We asked a cop who told us the way. Over the river and through the alleyway. Neat place.
