A "bright and artistic" teenager with mental health problems fell 100ft to her death from the Menai Suspension Bridge, an inquest heard.
Coroner Dewi Pritchard-Jones said at the Caernarfon hearing that Pauline Swatridge, aged 15, of Bangor Street in Y Felinheli had killed herself.
He added: “Unfortunately I have had many deaths in that locality. The barriers are so it's almost impossible for anyone to accidentally fall over them.
“My belief is this young lady climbed over the barrier and fell to her death.”
Mr Pritchard-Jones said the teenager had suffered from mental illness. Her body was found on rocks.
The hearing that the pupil of Ysgol Friars in Bangor was born in France but grew up in Surrey and then in Wales.
Pauline, who had been diagnosed with schizophrenia, could speak French, English and Welsh. She was particularly musical and talented at art.
Her family said her short life was "well-lived, filled with laughter, mischief, artistic creation and caring for others."
Pathologist Dr Mark Lord said there was a "significant impact" and she received multiple injuries.
Mr Pritchard-Jones added: "I prefer to steer away from trying to work out exactly what was in this young lady's mind at that particular time and to adopt the more modern practice and to record a narrative verdict."
The tragedy happened last May.
