St Patrick's Day is also known as the Feast of Saint Patrick and marks the date of the Irish patron saint's death.
Held in honour of Ireland's patron saint, St Patrick's Day is a holiday synonymous with partying, good food, and joyful Guinness drinking.
This entails placing a shamrock at the bottom of the cup, before filling it and finishing the drink as a toast to either the people present, to Ireland, or to St Patrick himself.
As such, not only are they now a classic symbol of St Patrick’s Day, but also of Irish heritage more generally.
St Patrick claimed during his time in Ireland to have found God, who told him a ship would be waiting to take him home at the coast.
