Tottering precariously above the Jungfraujoch railway in Switzerland sits the Sphinx Observatory, a scientific observatory and research facility. Called the Sphinx Observatory after the rocky summit on which it is located, this high-altitude observatory is one of the world's highest observatories at 3,571 m above mean sea level. Read on to know why this site is a must-see while at Jungfraujoch. It also boasts the second-highest observation deck in Switzerland, which is open to the public.

Why visit the Sphinx Observatory?

One of the world's highest observatories: Seated so high up, it's no surprise that Sphinx Obervatory is one of the world's highest observatories, fitted with a telescope that aids research and discovery.
Extensive views: While the observatory itself isn't accessible, the public viewing deck is situated next to the observatory. On one side, the Mittelland stretches out and provides views of the Black Forest and the Vosges, and on the other, the Aletsch Glacier with its 4000 m peaks around it comes into view.
Science and research: Besides offering breathtaking views, the observatory is the site of astronomical, geological and glaciological research (however, the laboratories cannot be accessed by the public). Over the years, the laboratory has its own electricity, internet and water connections.
The name is Bond, James Bond: The 1969 James Bond Movie *Her Majesty's Secret Service *was shot against the backdrop of this observatory. Even Bollywood movies like *The Hero: Love Story of a Spy *featured this iconic landmark.
