Krakelingen and Tonnekensbrand Geraardsbergen in Geraardsbergen
A UNESCO-listed double ritual in Geraardsbergen: a daytime procession up Oudenberg hill where officials drink wine containing live fish and bless ring-shaped breads, followed by an evening barrel-bonfire on the same hilltop. Documented since at least 1393, it is one of the oldest continuously observed folk rituals in the Low Countries.
In Geraardsbergen, local officials still drink wine from a sixteenth-century silver goblet containing live minnows as part of a ritual that predates the written record of the custom by centuries -- the city's oldest surviving account book, from 1393, already includes a line-item for the bonfire that closes the same day's events.
