Holocaust Memorial Day this Friday, 27 January, sees an interesting step in York, England, the city which saw the terrible massacre of its Jewish community on the site now occupied by Clifford’s Tower, in 1190. Although sidelined for many years, that has now become a well-known and well-described episode in the city’s long history and as usual there will be a ceremony at 6pm this Thursday evening at the famous grassy mound, including a Kaddish or prayer for the dead. This will be followed an hour later by a civic event at the Tempest Anderson Hall, relating the Holocaust to modern persecution across the world.
