For the Venice Art Biennale 2015, artist Chiharu Shiota introduced an installation named “The Key in the Hand” : a gigantic spider web made of red wool threads where we can see 50 000 keys suspended above two ancient boats. The keys have been collected by unknown people from all around the world to end up hung up on this monumental sculpture, like talismans ; they’re here to remind the memories of the places they have unlocked.
