57 kilometers
Temporary exhibition about the new Gotthard railway tunnel which will be opened later this year. Some stunning facts:
- longest railway tunnel in the world (57 km)
- also the deepest, being more than 2'300 metres below the rocky surface at some points
- 28.2 million tonnes excavated rock, reused for various things, including 6 new islands in Lake Uri

Terrible day for Brussels and Europe. Thinking of all victims, their families and friends.
