Saint David, or Dewi Sant, as he is known in the Welsh language, is the patron saint of Wales. He was the only Welsh saint to be canonised and culted in the Christian Church.
David came from an aristocratic family in Wales and was at the heart of the Welsh church in the 6th century. He became the abbot and biship of St Davids and died on 1st March 589 AD. He is buried in St David's Cathedral, Pembrokeshire. So respected was he that medieval pilgrims believed that two pilgrimages to St Davids were worth one pilgrimage to Rome.
March 1st, St David's Day, is now celebrated by Welsh people all over the world by wearing either of the national emblems - a leek or a daffodil.
