The Shamrock
All the same, even with Christianity’s newfound prominence, traces of Celtic culture remain. For instance, Ireland’s national symbol, the shamrock (a green, three-pronged leaf) represents the “Holy Trinity” of Catholic tradition – the Father (God), Son (Jesus Christ), and the Holy Spirit.
Gaelic
To top it off, the Celtic cross represents the region’s unique take on the Catholic cross. In addition, a lot of Celtic folklore stories, are still told in Ireland. Like Welsh, the Irish language, Gaelic, is a Celtic language. For the most part, Gaelic disappeared in the 19th century, when the English colonized Ireland, but the language is still spoken in the western part of the country.
