Anyone who was in Newcastle over the weekend might have been a bit intrigued to see a carboard box tower - but they might also have realised it wasn't there for long. 

On this occasion, it wasn't a mind-trick or an optical illusion, it was an art exhibiton.

This weekend, NOVUM Newcastle Summer Festival welcomed globally acclaimed visual artist, Olivier Grossetête, to the city.

The illustrious French artist, known for his cardboard structures crafted in collaboration with local communities, fashioned a temporary extension to Newcastle's Civic Centre.

In Newcastle, the monumental installation was built on Friday (August 11), on Ceremonial Way, adjacent to the Civic Centre, in an epic 8 hour participatory build.

On Sunday (August 13) the public came once again to take part in and witness the "Colossal Destruction"—a deconstruction event - which saw them destroy the creation.

Grossetête's team has been building his community-driven monumental constructions since 2003, engaging thousands of community members in his cardboard and tape escapades across five continents.

Kate Craddock of Curated Place, Creative Producer of NOVUM, said, "We were thrilled to welcome Olivier to Newcastle and to offer the local community a chance to create a monument that pays homage to our incredible city.

"Newcastle’s rich architectural heritage, including our famous bridges, the Georgian elegance of Grey Street, and the Grade II listed Civic Centre itself, all played a role in shaping Olivier’s final design.
