Le Lieu Unique is a center for contemporary culture located in Nantes, France.

Built in 1895 as the headquarters of the LU biscuit manufacturers, the building closed in 1986 and fell into disrepair, but became home to various theatre companies, such as Royal de Luxe.

[2] In 1998, restoration work on the only remaining tower began, conducted by Jean-Marie Lépinay, as well as regeneration of the factory by the French architect Patrick Bouchain, in one of his first major projects.

[3][4] Le Lieu Unique opened on 30 December 1999, during the "End of century" festival in Nantes.

A translucent double wall was designed to receive a collection of objects donated by the public which were then store in cans to be opened one hundred years later.
