After much searching, the location of the church where Jost (or Joost) rang the bell in the film (or movie) "The Way" was found to be the church of Santa María de Figueiras, not on The Way at all, but only 5 km from the cathedral in Santiago. I walked there two days after finishing my camino. I took some photos, two of which I have attached. They show the top of the cruceiro under which Jack (James Nesbitt) sat. Both sides of the cross are covered by black growths of some sort. Is it lichen? I've never seen anything like it. Yes, I rang the bell.
