St Illtyd's church is without doubt the oldest standing building within the County Borough of Blaenau Gwent. Although currently dedicated to St Illtyd, the original dedication of the church was to St. Heledd or Hyledd. Heledd was also a real person who lived in northern Powys in the early 7th century. Her brother, Cynddylan, was king of Powys until he was killed by the Anglo-Saxons. She appears in Canu Heledd ("The Song of Heledd") another series of poems, also composed in the 9th or 10th century Nikon D5200 Thanks for looking
