The garden stands as a memorial to the people of Kent killed in the First World War.
Proposals were raised for the memorial to be located in Maidstone or Rochester, but Canterbury was subsequently chosen in June 1920.
The memorial was dedicated by the Archbishop of Canterbury at the service with an address given by Admiral Hugh Evan-Thomas.
Lord Harris presented the garden to Henry Wace, the Dean of Canterbury, at the service.
