Although never formally canonized by Rome, Elen is traditionally considered a saint in the Welsh Church. She is known as Saint Helen of Caernarfon in English to distinguish her from the better-known Saint Helena ("Helen of Constantinople"). Elen was mother of five, including a boy named Custennin or Cystennin (Constantine).
She lived about sixty years later than Helena of Constantinople, the mother of Constantine the Great, whom she has been confused with in times past
Elen"s story is told in The Dream of Macsen Wledig, one of the tales associated with the Mabinogion. Welsh mythology remembers her as the daughter of a chieftain of north Wales named Eudaf or Eudwy, who probably lived somewhere near the Roman base of Segontium, now Caernarfon.
Since many characters in these tales are thought to be Christianized reflections of older deities (see: Welsh mythology), it has been suggested that Elen reflects (along with Rhiannon, etc) a tradition of goddesses of sovereignty. She is said to have ordered the making of Sarn Helen, the great Roman road running from Caernarfon to south Wales via Dolgellau, Pennal and Bremia (Llanddewi Brefi).
Though this road bears her name it is considerably older than Elen"s accepted time period.
Many other Roman roads in Wales bear her name (eg Llwybr Elen) and she is thus acknowledged as the patron saint of British roadbuilders and the protectress of travellers. There are over 20 holy wells in Britain dedicated to a "Saint Helen", although these are frequently taken as honoring the mother of Constantine the Great.
She is remembered for having Macsen build roads across her country so that the soldiers could more easily defend it from attackers, thus earning her the name Elen Luyddog (Elen of the Hosts).
