A rusted submarine strands on an abandoned field, at Arsenal,Venice. The submarine saw centuries of prosperity of marine insdusty in Venice; while also witnessed the falling of that glorious era. History is not always a continuous flow. It is sometimes stranded. The stranded moments of time became forgotten memorieds and obsolettes. Remains of marine weapons, battleship components, as well as other shattered pieces of history, are stranded here. I propose to build an exhibition center at this special site. It will become a shelter of those homeless objects, to recall the memory, and to inspire every generation。
