While St. Patrick’s Day is known for corned beef and cabbage and wearing green, it is a holiday to celebrate Saint Patrick, the patron saint of Ireland.

According to National Geographic, St. Patrick was from Britain and was kidnapped and sent to tend sheep. After seven years, he heard a voice in a dream that told him to return to Ireland. Upon returning he became a priest.

Today, there are a variety of traditions to celebrate the day. According to National Geographic, some well-known St. Patrick’s Day celebrations are located in New York City, Boston, Chicago, Dublin and various other locations. At the Chicago festivities the city begins by dying the Chicago River green.

While traditions vary place to place, Irish traditions can now be found in a college dorm room.
