The extraordinary Ark Nova concert hall recently left its home in Japan for the first time. It has a height of 18 m (60 ft), a width of 29 m (95 ft), and a length of 36 m (118 ft). Around 12,000 people visited the Ark Nova while it was in use and over 35 concerts were held there for 11 days. Now that the festival has come to an end, the Ark Nova has been dismantled and is headed back to Japan. Sources: Lucerne Festival, Aerotrope
