Desc: Canfranc, l'or et le tungstène: Directed by Xavier Pajot. Transparent in the shade, opaque in the sun. Its melting point is, among metals, the highest. It was sought out to reinforce metal alloys. It increases the penetrative capacity of explosive projectile heads. It has the same density as gold. Gold and tungsten passed through the dormant train station of Canfranc during World War II. They wanted to silence the man who shed light on the issue of smuggling and the obscurity remains: how much gold passed through Canfranc between 1939 and 1945? Where did this gold come from? Where was it headed? Canfranc, gold and tungsten is a documentary that lifts the veil of this strange time of trafficking.
