Near the Swiss city of Basel, there are five mountains with the same name - Belchen. They form a giant sundial, which was used by the Celts to measure time and space. The Celts built the settlements that developed into modern day Basel on the basis of a magic triangle linked to this sundial. (The Mysterious Switzerland series is produced by SRG SSR idée suisse.)
