There are 46 AONBs in Britain (33 wholly in England, four wholly in Wales, one that straddles the Anglo-Welsh border and eight in Northern Ireland). The first AONB was designated in 1956 in the Gower Peninsula, South Wales. The most recently confirmed is the Tamar Valley AONB in 1995, although the existing Clwydian Range AONB was extended in 2012 to form the Clwydian Range and Dee Valley AONB, and the Strangford Lough and Lecale Coast AONBs were merged and redesignated as a single AONB in 2010.
