Shamrocks and Four-Leaf Clovers
St. Patrick choose a shamrock or a three leaved clover to symbolize the church's Holy Trinity - Father, Son, and Holy Spirit. A four-leaf clover is not a shamrock, but because it is rare to find it symbolizes good luck. (credit: Paul McErlane/Getty Images)
Celtic Music

The Leprechaun
The leprechaun comes from the Celtic belief in fairies and tiny men. In Celtic folktales, they are known for their trickery to protect their treasure. In 1959, Walt Disney released a film that created an American cheerful and friendly image of the leprechaun which is now associated with St. Partick's Day. (credit: AP)
Wearing Green
Over the years, it has become a custom to wear green on March 17. However, this is mostly a U.S. custom because green is considered unlucky in Ireland. The color green is connected with the old green flag - a time when Ireland was not free. (credit: Mark Ralston/AFP/Getty Images)
Chicago River Dyed Green
Since 1962, Chicago has dyed its river green. It started out as a way for sewer workers to check for sewer discharges. It has now become a custom to dye the river green on St. Patrick's Day. Other cities and states have picked up on the tradition.(Photo by Frank Polich/Getty Images)
