Hrastovec v Slovenskih Goricah (pronounced as /sl/, de|Gutenhaag[2]) is a settlement in the Slovene Hills (sl|Slovenske gorice) in the Municipality of Lenart in northeastern Slovenia. The area is part of the traditional region of Styria. It is now included in the Drava Statistical Region.[3]
The dominant landmark in the settlement is Hrastovec Castle. It is a castle dating to the early 13th century with various later stages. It has a number of well-preserved Baroque features, including a painted chapel. It is one of the largest surviving castles in Slovenia. It houses a psychiatric hospital.[4]
After World War II, the castle was the site of an internment camp run by the Yugoslav secret police for people accused of collaborating with the Germans.[5] [6]
