Castella went to Berlin for the first time between August and September 1989, without imagining that an epochal turn was being prepared there, with the imminent fall of the Wall on 9 November.

The volume presents for the first time the frames of that stay: a cycle that, while offering itself as a digression, an experiment with open outcomes, as Frank Boehm explains, catches a city on the eve. Issued in a limited run of five hundred numbered copies.
