Avicii Arena

This guide explains why Stockholm's Avicii Arena is also the sun: a scale model of the solar system, built in 1989 by two professors from KTH and Stockholm University, shrinks the whole system by twenty million times and scatters it across real Swedish ground. You'll hear where Mercury and Earth land within a few kilometers of the dome, why Jupiter hangs unnoticed above a hotel lobby at Arlanda, and why Saturn sits in a square in Uppsala beside the old observatory of Anders Celsius. The trail keeps stretching outward, planet by planet, well beyond the edge of the city.
