King Alfonso II the Chaste (791-842) moved the capital of the kingdom of Asturias to Oviedo in 791. He enlarged the city with a new cathedral, palaces, churches and city walls. Examples of these buildings which are still existing are: San Julián de los Prados, ("St Julian in the fields"), also called "Santullano", the head of the church dedicated to San Tirso, ("Saint Thyrsus"), and the Cámara Santa, ("Holy Chamber") which is a chapel which belonged to the palace of the king.
