Big Bang
City Festival

Fri 15.10.2021 Sun 30.01.2022

Did you know that Leuven is the birthplace of the Big Bang Theory? In 1931, Georges Lemaître introduced his revolutionary theory of the primaeval atom and the expanding universe. And it rocked the world of science to its core. It’s no small wonder then that Leuven has made the Big Bang the theme of its sensational city festival.

We'll be igniting our very own world-shattering cultural Big Bang in the autumn of 2021. BANG! sucks you into a sensory journey through how the Big Bang continues to inspire art and science today. Enjoy music, exhibitions, events, and everything that makes life BANG! exciting!

BANG! is a KU[N]ST Leuven initiative, a joint venture between KU Leuven and the City of Leuven. Funded by the Flemish Government and the Belgian National Lottery.

BANG! extends the red carpet with some exhibitions, featuring one-of-a-kind pieces from at home and abroad. Tying them all together is the Big Bang and a fascination with the cosmos.
