Halloween – An Ancient Mystery Trailer (2025)

18 October 2025 Factual, Mystery 90 mins

Halloween, often seen as an American custom, dates back to the Celtic festival of Samhain, which was already known in Gaul and Ireland. A two-thousand-year-old bronze calendar attests to this tradition. At that time, people believed that the gates to “another world” were open. The documentary uses archaeological evidence to show how Celtic customs gave rise to the modern Halloween festival.
