More than a dozen theatre-goers in Germany needed medical treatment after viewing a radical feminist opera which features naked nuns on rollerskates, a lascivious depiction of Jesus Christ and the grilling of human flesh.

The “Sancta” opera, which has an age restriction of over-18s and numerous content warnings about sex and mutilation, proved to be too intense for some audience members at the Stuttgart opera house.

According to the Stuttgarter Zeitung, a local newspaper, a total of 18 audience members came down with nausea, requiring first aid and even a doctor in some cases, while viewing the show.
