Hogwarts Castle.
Hogwarts School of Witchcraft and Wizardry is a British wizarding boarding school teaching the magical arts, located in Scotland[1] inside Hogwarts Castle. The castle is in the mountains near a loch. The precise location of the school can never be uncovered because it has been rendered Unplottable. Also, to Muggles the school looks like an old abandoned castle. Similarly, most wizarding schools locations are protected in order to prevent their ways of teaching being revealed, as well as protect the students and schools themselves from any harm. Hogwarts is more-than-likely a fantasy world of its own.
Established around the 9th or 10th century, Hogwarts is considered to be one of the finest magical institutions in the wizarding world, though other notable schools include Beauxbatons Academy of Magic and the Durmstrang Institute. Children with magical abilities may be enrolled at birth, and acceptance is confirmed by owl postat age eleven.
The school's motto is Draco Dormiens Nunquam Titillandus, which translated from Latin means "Never tickle a sleeping dragon".
