Yes, that is a half-nude woman with wings and a gigantic baby head performing at the opening ceremony today for Switzerland’s $12 billion, 35-mile Gotthard rail tunnel, the longest in the world.

I had assumed that the figure was an angel, acting in remembrance of the nine workers who died during the tunnel’s 17-year construction. The Tagesspeigel reports that it’s actually a bird.

Watch a highlight reel of the performance above, or the entire opening ceremony near the tunnel’s entrance in Erstfeld below.

German director Volker Hesse put the show together and if you have any clue what’s going on please let us know.
