Capel Curig takes its name from St. Julitta’s Church in the ancient graveyard by the river bridge on the Llanberis road.  Tradition claims this chapel to be the 6th-century foundation of St Curig, a Celtic bishop. Centuries later, probably when the present ancient church was built, the name appears to have been Latinised as Cyricus, which is the name of a 4th-century child martyr whose mother was Julitta. They are usually named together as Saints Quiricus and Julietta.  Does that help explain?  This is unused J. Salmon card *1037, showing its age but still clean enough for Grade: 1
