Saint Patrick was a fifth-century Christian missionary and bishop in Ireland. Known as the “Apostle of Ireland”, he is their primary patron saint. He is venerated not only in the Catholic Church, but also by the Anglicans, the Lutherans, the Old Catholic Church, and in the Eastern Orthodox Church.
Saint Patrick’s Day is observed each year on March 17, believed to be the date of his death. It is celebrated both in Ireland and other places throughout the world as a religious and cultural holiday. It is also a celebration of Ireland itself.
