To visit the military works of Montsec, go beyond the village along I.C. 19 and stop at the last houses on the left, where there is an enormous concrete shelter, which served as an artillery telephone exchange, (photo, p. [78]). A narrow road leads from this shelter to the entrances of the tunnels on the crest. (Time required to visit: one hour.)
