Canfranc railway station in Aragon, Spain.
Opened in 1928, it was the stunning centrepiece of the line between Béarn and Aragon, across the French-Spanish border.
But in 1970 a runaway train destroyed a bridge on the French side.
They decided not to rebuild it, and as a result the station was abandoned.
