The sinking of the RMS Titanic remains one of the most enduring and mysterious tragedies of the 20th century. For decades, investigators and amateurs alike have floated theories for why it occurred and who was to blame for the extraordinary loss of life, but no one answer could fully explain what happened.

From our window one can see a set of the film The Green Years, directed by Paulo Rocha in 1963. This was our starting point: guided by Rocha's gaze, we look back at the places of that film.
