‘”Cafe Little Boy” has its origins in the story of the Fukoromachi primary school in Hiroshima, destroyed by the atomic bomb nicknamed “Little Boy” . Only one wall remained standing, on which the survivors left messages for family and friends. This evolving installation invites visitors to write on the walls in chalk in response to that tragic event, further elaborating the collective memory’. (information on wall outside room). I liked the fact only 5 people were permitted in the room at any time.
