No more abseiling from the roof. No more desperate fugitives plummeting to their deaths on the cobbled street below. Nothing was to get in the way of the new, impregnable Wall. It would keep the state’s citizens trapped inside the GDR until... they resigned themselves to their fate and simply stopped resisting."
