of the most important Celtic Saints of Celtic Christianity for each Celtic nation have become the focus for festivals, feasts and marches: Ireland – Saint Patrick's Day, Wales – Saint David's Day, Scotland – Saint Andrew's Day, Cornwall – Saint Piran's Day, Isle of Man – St Maughold's Feast Day and Brittany – Fête de la St-Yves and Grand Pardon of Sainte-Anne-d'Auray Pilgrimage. Attitudes and customs associated with the routine of the year's work, religious beliefs and practices survived the coming of Christianity in the conservative rural areas of much of the Celtic countries. All over these lands there were sacred places which had earned their status in pre-Christian times and which had only been gingerly adopted by the Christian church and given a garnish of Christian names or dedications, hills, stones, and especially wells which can still be seen festooned with rags in observance of an old ritual.

In Gaelic folklore, it was considered a particularly dangerous time, when magical spirits wandered through the land, particularly at nightfall. The other important feast days that also continued to be celebrated under Christian guise, but often with a pagan spirit were Imbolc (Gŵyl Fair y Canhwyllau in Welsh), the start of lambing, now the feast day of St Brigit and Beltane, the spring feast, now May Day (Calan Mai in Welsh). In their pilgrimages the people combined the celebration of a holy place and a holy day. Pilgrimages are still an important feature of country life, particularly in Ireland, Brittany and Galicia. The most impressive pilgrimages include Croagh Patrick on the west coast of Ireland on the last Sunday in July (the beginning of
