St David is the patron saint of Wales, celebrated for his piety and dedication to Christianity. He is believed to have lived in the 6th century and founded a monastic community at Glyn Rhosyn, now known as Glastonbury. His teachings emphasized simplicity and humility, and he is often depicted with a dove, symbolizing peace. St David's Day is celebrated on March 1st each year, marking his contributions to the Christian faith and Welsh culture. Many people wear daffodils or leeks, which are national symbols of Wales, to honor his legacy. His shrine is located in St Davids, a city named after him.
