"I seal my office with a spell none but a wizard could break!"

This spell (incantation unknown) enables a witch or wizard to seal a room in such a way that only witches or wizards could break it.[1]

Severus Snape cast this spell on his office at Hogwarts Castle.[1] He suspected, incorrectly, that Harry Potter, a fourth year student at the time, had broken it to steal potion ingredients,[1] when, in reality, Barty Crouch Jr (under the guise of Alastor Moody) had broken the seal in order to steal Boomslang skin from Snape's personal stores, so he could keep making Polyjuice Potion.[2]
