Moaning Myrtle's Bathroom

Moaning Myrtle's Bathroom appears in Harry Potter.

Moaning Myrtle's Bathroom, a haunted girls' lavatory on the second floor of Hogwarts, emerges as a pivotal location in the Harry Potter series, primarily due to its connection to the long-sealed Chamber of Secrets. Introduced in the second book, it serves as the hidden entrance to the Chamber, activated by a serpentine sink, and remains a recurring site for magical mishaps and ghostly interactions throughout the series. While its central role diminishes after the Chamber's destruction, it retains significance as Myrtle's eternal haunt and a place of occasional refuge and experimentation for students.
