San Luis de la Paz, Gto. Sunday April 10, 2011. As we announced here a few days ago, this Sunday began the guided tours to the Jesuit tunnels. The starting point was at the Alameda Melchor Ocampo. We took the tour, organized by Professor Guillermo Contreras and Mr. Gustavo Castillo, passionate promoters of tourism in San Luis de la Paz. Along with them, we visited the tunnels, and other local historical constructions.
