Stonewall High is a state secondary school that Harry Potter would have attended if he had not received a letter of admission to Hogwarts School of Witchcraft and Wizardry instead. According to Harry's cousin, Dudley Dursley, new students at Stonewall High are subjected to a hazing ritual in which their heads are stuffed down a toilet on their first day. It is possible that they bully younger and weaker children, like Harry. The school's uniform was grey, but in an effort to save money, Harry's Aunt Petunia dyed some of Dudley's old clothes to make a grey uniform for him.
