The waters around Anglesey were described by Nelson as being
the most treacherous in the world.
The southern boundary of North Wales is somewhat arbitrary
and depends on the use being made of it. For example the boundary of North
Wales Police differs from that of the Environment Agency Wales.
North Wales has a very diverse and complex geology with
Precambrian schists along the Menai Strait and the great Cambrian dome behind
Harlech and underlying much of western Snowdonia. The region is steeped in
history and was for almost a millennium known as the Kingdom of Gwynedd. The
mountainous stronghold of Snowdonia formed the nucleus of that realm and would
become the last redoubt of independent Wales.
Two of the three Welsh UNESCO World heritage Sites are in
North Wales. These are the Edwardian castles and town walls of the region at
Caernarfon, Conwy, Beaumaris and Harlech and the Pontcysyllte Aquaduct and
canal. North Wales has many valleys and mountains and is mostly rural and its rural
nature, combined with its many coast lines has made tourism the main industry.
The eastern parts contains the most populous areas, with
more than 300,000 people living in the areas around Wrexham and Deeside.
Wrexham is the largest town, with a population of 68,000.
There is a distinct regional identity within North Wales and
the local dialect of the Welsh language is different from that of other parts
of Wales. A person from North Wales (especially one who speaks with this
dialect or accent) is known as a North Walian, or a Gog (from the Welsh
gogledd, meaning "north").
