Since 2005, on the occasion of the Day of Holocaust Remembrance and Counteracting Crimes against Humanity celebrated in Poland on 19 April, the Grodzka Gate–NN Theatre Centre has organized the artistic and educational action Letters to Henio.
On this day, citizens of Lublin send letters to Henio Żytomirski – a Jewish boy who was born in 1933 in Lublin and was murdered by the Nazi in a gas chamber, probably in November 1942. The life story of this boy became the inspiration for the Grodzka Gate–NN Theatre Centre to prepare the exhibition entitled “A Primer,” devoted to the life of children in Majdanek concentration camp.
