Barrel Rolling Ceremony in Rátót
Celebrating the completion of a bridge by rolling a barrel across it is a longstanding tradition. According to old superstition, being the first to cross a new bridge brings bad luck – therefore, a barrel is rolled across it as soon as the structural works are completed, in order to “divert” the curse onto the barrel. We reinterpreted the tradition somewhat, as the bridge in question is not completely new and we also waited with the ceremony until the bridge was ready for traffic.
