You will find a QR in each language at the beginning of the exhibition, which will guide you from decade to decade along the timeline. In it, we tell you about random events of a scientific, technical, industrial and human nature, with global repercussions, or that have occurred in Euskadi, Bizkaia, on the left bank, or in Portugalete. It is not intended to be exhaustive, they are just strokes to put into context what you can find in the exhibition so that you can pull the thread you want. You will also find QR codes on the floor of the rooms to obtain this information.
