On 27 January the Stumbling Blocks' laying ceremony took place, starting from Campo Maria del Giglio, as part of the 2022 Holocaust Memorial Day celebrations. A stumbling block is a concrete cube placed into the pavement and bearing a brass plate inscribed with the name and life dates of victims of Nazi extermination or persecution. A total of 75,000 stones recall the victims of the Shoah in thousands of places and over thirty European countries. This makes the project, initiated by German artist Gunter Demnig in 1992, the largest decentralized Memorial to the Shoah in the world. Twenty-nine stumbling blocks were laid in the Venice city centre, in addition to the one hundred and five already placed since 2014. For the first time this year the project involves the mainland, with the laying of the first stumbling block in Mestre, on 28 January in Via del Rigo 2. Taking part in the commemoration were the President of the City Council, Ermelinda Damiano, Paolo Navarro Dina of the Jewish Community, Marita Liebermann, director of the German Centre for Venetian Studies, Marco Borghi president of the Municipality of Venice-Murano-Burano, Giovanni Sbordone director of the Venetian Institute for the History of the Resistance and Contemporary Society and Council of Europe Italian Director, Luisella Pavan-Woolfe.
