The centenary of the Tunguska exposion in Siberia was in 2008. To commemorate this event, artists were invited to build a temporary installation in the city of Krasnoyarsk. Artist group Observatorium came up with the Epicentrum: a crooked, bright orange carrel supported by 14 tree trunks, 5 m off the ground. All visitors were free to climb to ‘the epicentre of the Epicentrum’ and, once there, removed from the world, ponder what happened a century ago.

In the context of the commemoration of Tunguska, a comet impact that occurred one hundred years ago, Observatorium developed Epicentrum, a crooked study cell resting on fourteen tree trunks. The tree trunks referred to the area where the blast knocked over and stripped bare millions of trees. Visitors could climb to ‘the epicentre of the Epicentre’ by themselves.
