Legacy 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 (e.g. 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.
