The partnership with the Vienna Burgtheater resumed in 2025. For the first time in the recent history of the festival, Austria’s famous national theatre visited Bregenz during the summer festival – with guest performances that featured a world premiere and a co-production. The co-production, which opened at the Kornmarkt Theatre on 18 July 2025, was bumm tschak oder der letzte Henker, the latest work by the multiple-award-winning Austrian playwright Ferdinand Schmalz. The play was directed by the Swiss stage director Stefan Bachmann, artistic director of the Burgtheater.
