The underground of Fort Liberia

The underground of Fort Liberia, Also Called " The underground of 1000 steps" , Fort Liberia's Underground is located between Fort Liberia and the fortified town of "Villefranche-de-Conflent" in the "Pyrenees-Orientales" ( France ).
But the name that was given to this underground is not true since it has "only" 734 steps, the equivalent of the present number of steps to climb to the top of the "Eiffel Tower" in Paris. At the half of the underground there is a magnificent panorama of the city, as a reward for the courageous people who are walking up the stairs on foot.
