Thanks for the query. It looks like you’ve provided a snippet in Swedish: “var är förrädarna inspelat” which translates to asking where "Förrädarna" was filmed. Direct answer:

• Förrädarna is a Swedish TV reality game show that has been filmed at Häringe slott (Häringe Palace), which is located just south of Stockholm in Harginge/Häringe in Södermanlands län. The production has commonly used Häringe slott as its filming location for the game’s setting. This is corroborated by multiple Swedish media reports noting the slott as the filming venue for the series.

If you’d like, I can pull up the latest official statements or updated filming details from TV4 or Häringe Slott to confirm any recent seasons or location changes.
