Poland's bus route 666, renowned for its ominous number and destination of Hel, a seaside resort town, is undergoing a rebranding. Following persistent objections from religious conservatives, PKS Gdynia, the operating company, has decided to alter the number, symbolically "turning the last 6 upside down."

The route's notoriety stemmed from the association of 666 with the "number of the beast" in the Bible and the similarity between "Hel" and "Hell." This combination proved particularly popular with tourists from English-speaking countries. However, some within Poland found the route number offensive, equating it with the promotion of Satanism.

The decision to change the number has sparked mixed reactions online. While some lament the loss of a unique marketing opportunity and a globally recognized symbol, others believe the change is unnecessary, pointing out the linguistic difference between the Polish word for hell, "pieklo," and the English "Hell." Regardless, the route's fame had spread internationally, attracting tourists who chose the bus specifically for its infamous number.

The change has even prompted satirical suggestions, such as renaming the town of Hel altogether to align with Poland's predominantly Roman Catholic values. The new route number will take effect on June 24th, marking the end of an era for this unusual piece of Polish public transport history.
