Westport, Éire (Republic of Ireland). On each side of the small organ in the Church of Holy Trinity is a stained glass window showing St George, and St Patrick. Saint Patrick; By the seventh century, he had come to be revered as the patron saint of Ireland. Saint Patrick's Day is observed on March 17, the date of his death. Pious legend credits Saint Patrick with banishing snakes from the island, chasing them into the sea after they attacked him during a 40-day fast he was undertaking on top of a hill. However, all evidence suggests that Ireland never had snakes.
