Wales also has five Areas of Outstanding Natural Beauty. These differ from National Parks in that the authorities have a duty to conserve and enhance the natural beauty of the landscape but do not have an obligation to promote the enjoyment of the public and additionally, they have no control over planning. In 1956, the Gower Peninsula became the first designated AONB in Britain. Other AONBs are: the whole of Anglesey; the Llŷn Peninsula; the Clwydian Range and Dee Valley; and the Wye Valley, part of which is in England.
