Hogwarts School of Witchcraft and Wizardry is a British wizarding school that teaches the magical arts, located in Scotland inside Hogwarts Castle. The castle is in the mountains near a loch. Established around the 990 A.D. it is considered to be one of the finest magical institutions in the wizarding world.

By the use of a sorting hat, students are sorted into one of the four houses, Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. The student after being sorted remains in that house until the end of their schooling years.
