The Conwy County, or officially known as the County of Conwy (Welsh : Sir Ddinbych in Conwy), is an administrative county and unitary authority area in Wales. The Conwy County borders onto Snowdonia National Park and it covers an area of 787 km2, making it the smallest unitary authority in Wales and one of the smaller counties in the United Kingdom. The county has two large peninsulas, separated by the estuary of the River Conwy, which are highly populated and where most of the population lives and works. As with many historic counties, Conwy's boundaries changed little even after the local government reforms of 1974 and 1996. Generally speaking it still has almost the the same shape as when it was formed in 1284.
