This photo is taken from a containment dyke against avalanches built in 1963 called 'Diques Cola del Caballo'. This structure with a very particular shape is a combination of empty dam and rake dam and has two purpose: with its higher part in the shape of rake it cuts the avalanches, with its weirs it filters the excess of water. The aim was to protect the Canfranc station below.

The Canfranc International railway station is a formerly railway station located in the Spanish Pyrenees, in the Aragón region. The station's operation abruptly ended on March 1970, when a train derailment on the Pau-Canfranc railway line demolished a bridge on the French side of the Pyrénées.

After the closure of the route the station became inoperative and started to deteriorate. In 2013 the government of Aragon started to make plan for the rehabilitaion of the station. A 5-star hotel from the Barceló Hotel Group is due to open on the 24 January 2023.
