The construction of the railway up to the Jungfraujoch in Switzerland's Bernese Alps began in 1896. It was then that an opening, covered by a wooden door, was created in one of the railway tunnels in order to clear debris generated during the tunnel's construction. This door to the Eiger later proved vital in a number of rescue missions to save climbers attempting the ascent of the Eiger's North Face.
