Private citizens put up a memorial on West Berlin’s Gröbenufer (today known as May-Ayim-Ufer) near the Oberbaumbrücke in November 1961. The stone was dedicated to an “unknown fugitive” who has since been identified as Udo Düllick. In 1984 the site was expanded to honor the memory of eleven other victims. Today only the original memorial stone remains; a Berlin Wall History Mile info board explains its background and recalls the people who died at the Berlin Wall. Five of them were children.
