This week, as the world prepares to mark International Holocaust Remembrance Day, a year after the COVID pandemic closed historical sites around the globe, Holocaust memorials, museums, and national and international institutions, are still challenged by the cancellation of perhaps the most iconic and resonant rituals of remembrance: gathering and commemorating at the actual sites where the mass murder was perpetrated. There’s been a flowering of innovative commemoration initiatives providing virtual access to memorial sites, and ways of commemorating from a distance via social media platforms and other online tools. Memorials and other Holocaust-related institutions intensified their activities on Zoom, Instagram, Twitter, Facebook and YouTube most particularly between March and May, the period in which most of the Nazi camps were liberated 75 years ago.
