What is Saint Patrick’s Day, and why do we celebrate it?

St. Patrick’s Day is one of the most important and highly anticipated dates in the Irish calendar. A day to celebrate our Irish culture with some traditional Irish music and a jig, watching the annual parade, and washing it down with a pint of Guinness. But the celebrations go much further than this small island, with landmarks worldwide turning green for the occasion. From the Empire State Building to the London eye, the Burj al Arab to Niagara Falls and even the Chicago River turning green to honor St. Patrick’s Day. The holiday started as a religious event to commemorate Ireland’s Patron Saint, but over time it has become a worldwide event to celebrate Irish culture and heritage.

Born in Great Britain, St. Patrick was captured as a teenager and taken to Ireland where he was sent to work as a slave and tend the sheep on the mountain.

He returned years later as a priest to spread the message of Christianity to the Irish people, using the shamrock to explain the Holy Trinity. This is why shamrocks have long been associated with St. Patrick’s day.

Why green on St. Patrick’s Day?

Known as the Emerald Isle, Ireland has long been associated with the color green symbolizing patriotism and our spectacular green landscapes. However, blue was the original color associated with St. Patrick and Ireland which can be seen in ancient Ireland flags.

Legend has it the color green makes you invisible to Leprechauns, so they won’t pinch you! It’s thought this tradition started in America and has since been adopted worldwide as the color of choice. It is now ‘essential’ to wear green for your St. Patrick’s day outfit, you don’t want to risk getting pinched!
