Symbols
The most common St Patrick's Day symbol is the shamrock. The shamrock is the leaf of the clover plant and a symbol of the Holy Trinity. Many people choose to wear the color green and the flag of the Republic of Ireland is often seen in St Patrick’s Day parades around the world. Irish brands of drinks are popular at St Patrick’s Day events.
Religious symbols include snakes and serpents, as well as the Celtic cross. Some say that Saint Patrick added the sun, a powerful Irish symbol, onto the Christian cross to create what is now called a Celtic cross. Other Irish-related symbols seen on St Patrick’s Day include the harp, which was used in Ireland for centuries, as well as a mythological creature known as the leprechaun and a pot of gold that the leprechaun keeps hidden.
