According to legend, Slytherin had built a hidden chamber in this castle, known as the Chamber of Secrets. Shortly before departing, he sealed it until that time when his own true heir returned to the school. The heir alone would be able to open the Chamber of Secrets and unleash the horror within, and by so doing, purge the school of all those who, in Slytherin's view, were unworthy to study magic.
