Durmstrang Institute

Durmstrang Institute is a fictional magic school in the Harry Potter books, similar to Hogwarts. Durmstrang is thought to be located in northern Europe, possibly in northern Russia, and existed at least 700 years ago, as that was when they began participating in the Triwizard Tournament. Its headmaster is Igor Karkaroff.

Like Hogwarts, Durmstrang is located inside a castle. The castle is only four stories tall and fires are only lit for magical purposes. It has very extensive grounds. Durmstrang has a reputation for teaching the Dark Arts, possibly because of its former headmaster, Igor Karkaroff. Karkaroff was a Death Eater, but he got out of Azkaban by giving the Ministry of Magic dozens of names of his co-conspirators. He does not admit Muggle-borns to his school, and is said to have not only been teaching them Defence against the Dark Arts but the Dark Arts themselves.

Bulgarian Quidditch Seeker, Viktor Krum, attended Durmstrang, and was still in school during the 1994 World Cup. In the 1994 Triwizard Tournament, Durmstrang's champion was, to nobody's surprise, Viktor Krum. It was ironic that Krum attended the Yule Ball with Hermione, who is Muggle-born and wouldn't have been admitted at his school.

After the events of Harry Potter and the Goblet of Fire, Karkaroff fled after Lord Voldemort rose again. It is not known who took over, or whether the school's reputation improved or worsened due to this.
