Valero di Bouvignes, also known as Walhère d'Onhaye, was a 12th-century Catholic priest born in Dinant. He is remembered for his moral teachings and his eventual martyrdom. According to local tradition, he was killed while crossing the Meuse river by a fellow clergyman. This act of violence reportedly occurred after Valero criticized the other priest for his immoral lifestyle and called for a change in behavior.
