Visakha dasi and Radha Mohan das represented Bhaktivedanta Manor at the Holocaust Memorial Day event organised by Hertsmere Borough Council.
The event began with a candlelit parade through Bushey High Street, followed by a ceremony at The Bushey Arena.
Proceedings included recitals, memorials, prayers and a two-minute silence led by local dignitaries, as well as song and music by schoolchildren.
Holocaust Memorial Day is observed internationally to remember the millions of Jews murdered during the Holocaust, alongside the millions of other people killed under Nazi persecution of other groups and in genocides that followed since, in Cambodia, Rwanda, Bosnia and Darfur.
