Giant light installations illuminated the north face of the Jungfrau Mountain in Switzerland on Wednesday night and through the wee hours on Thursday, as the weather was favorable for hosting the light show, which is a part of the celebrations to mark the centenary year of Jungfrau railway.

The light installations, first put on show by artist Gerry Hofstetter on Jan. 1, attracted much international attention and a second illumination is now planned for this week, according to a statement released by the Jungfrau Mountain Railway authority on Jan. 11.

“With fine weather forecast for this week, Hofstetter expects to be back in action from Wednesday to Friday, 11 to 13 January, projecting more attractive images on to the Jungfrau,” the railway authority said.

The Swiss artist projected the flag of Switzerland and a portrait of Adolf Guyer-Zeller, the founder of the Jungfrau railway, onto Jungfraujoch peak in the Bernese Alps.

The Jungfrau railway, Switzerland’s leading mountain railway, first began operations in the year 1921. It carries on average 700,000 passengers every year, from Kleine Scheidegg to the Jungfraujoch peak. The Jungfraujoch station, at an altitude of 3,454 meters (11,332 feet), is Europe's highest railway station.
