Every year, people of Welsh origin celebrate their patron saint—St David (Dewi Sant). This saint lived till 100 years old and founded several churches and a monastery in Wales. He became an archbishop. After 500 years after his death, St David was canonised, and March 1st was included in the church calendar as St David's Day.
This day is also a day of Welsh culture. People visit a special church mass during the holiday. There are parades, choral recitals, and literature readings as well. National flags flutter in the streets of towns and villages as this day is also about national pride and the festive mood is in the air. Traditionally people wear their national costumes or pin a daffodil or leek to the clothes (they are the flower symbols of Wales). Restaurants offer "cawl"—a traditional meal on St David's Day, cooked of leek and other locally grown produce.
