"Several times, I happened to find myself alone with these "quiet fortresses," especially in inclement or snowy weather. For several hours, I walked tirelessly around the high pastures, or along the water reservoirs, the vault, looking for the best picture possible.

In our mutual silence, I absorbed their impressive and reassuring presence, their high mountain fortified castles looking. And those great "shelters," mine for a few hours, then kindly revealed to me some of their secrets."
