The Leuven Big Bang City Festival – BANG! – runs from 15 October 2021 through 30 January 2022. It’s all about the majesty and wonder of the cosmos and our place in it, explored through the imaginings and intellect of scientists and artists. The topic itself is no accident. Nearly a century ago, it was here in Leuven that Georges Lemaître first introduced the Big Bang theory. 

BANG! inventively highlights the intersection of science and art through exhibitions, installations, performances, happenings, lectures, and more on this glocally relevant theme.

The City Festival is a KU[N]ST Leuven initiative, a joint venture between KU Leuven and the City of Leuven.
