Wales is a constituent country of the United Kingdom, characterized by its borders with England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. Its physical geography is largely mountainous, featuring Snowdonia in the northwest, home to Snowdon (Yr Wyddfa), the highest peak at 1,085 meters (3,560 ft), alongside a varied coastline that spans approximately 1,680 miles, including the large island of Anglesey. Historically, the exploitation of the South Wales Coalfield during the Industrial Revolution spurred the development of major port cities like Cardiff—its capital and largest city—Newport, and Swansea, while much of the country remains rural, with economies centered on agriculture and tourism. As of 2014, Wales had a population of about 3.092 million, experiencing a mild, cloudy, wet, and windy climate influenced by the Atlantic Ocean.
