Near the Quidditch Training Grounds, there is a secret room behind a stained-glass window depicting the Hogwarts crest. In 1991, four Bertie Bott's Every Flavour Beans and a Chocolate Frog Card (Merlin) lay in the room. The room was found by a student in 1867 and again by Harry Potter in 1991 in his first flying lesson. Harry's accomplishment was congratulated by his teacher Madam Hooch.
