Sur les vestiges du mur de Berlin, des photos de touristes révèlent des archives invisibles à  l’oeil nu

Vingt-cinq ans après sa chute, le  Mur de Berlin attire toujours de nombreux curieux. Autrefois frontière, il est aujourd’hui le principal lieu touristique de la capitale Allemande. En mixant archives d’hier et photographies d’aujourd’hui, l‘office de tourisme de Berlin  a également voulu en faire un lieu de mémoire et de transmission et un outil de promotion des musées de la ville.

Afin que les touristes n’oublient pas l’histoire qu’il recèle, et ne sous-estiment pas le patrimoine historique qui se cache derrière ces ruines, l’office de tourisme de Berlin  et l’agence allemande  BBDO ont mis en place, en juin 2014, l’opération  Berlin Museum  Flashback.

A cette occasion, des rétroprojecteurs ont été disposés le long des vestiges du mur dans plusieurs quartiers de Berlin. Les projections diffusées par ces appareils sont invisibles à  l’œil nu mais elles se révèlent lorsqu’une photo est prise et le flash se déclenche. A mi chemin entre le street art et le travail de mémoire, cette opération a plongé le touriste au cœur de l’histoire de Berlin.

Un concept simple mixant archives et photographie

Le concept est simple : le touriste repère tout d’abord l’une des bornes rouges signalant l’opération Berlin Museum  Flashback. Il se place face à  la borne  et pose devant une partie du Mur restée intacte, comme il l’aurait fait en temps normal. Lorsque le photographe actionne le flash (étape obligatoire), les capteurs de la borne le détectent et projettent  automatiquement les images d’archives (invisibles à  l’œil nu) sur le Mur.

Résultat: Les touristes qui posent ont la bonne surprise de découvrir sur leur cliché un nouveau décor : en arrière-plan s’est superposée une image historique, accompagnée du message «  Découvrez l’histoire cachée de Berlin   ».

Présentation vidéo du projet:

Outil original de promotion des musées de Berlin  

Cette opération avait également pour but d’inciter les voyageurs à  se rendre dans les musées berlinois pour approfondir leurs connaissances des faits historiques et à  s’intéresser plus amplement à  l’histoire de Berlin, dont ses parties Est et Ouest furent séparées durant près de trente ans.

L’opération a atteint ses objectifs puisque la fréquentation des musées a significativement augmenté et les photos customisées avec ces événements d’une autre époque ont déjà  fait le tour des réseaux sociaux.
