Newcastle upon Tyne, commonly known as Newcastle, is a city in Tyne and Wear, North East England, 103 miles south of Edinburgh and 277 miles north of London on the northern bank of the River Tyne, 8.5 mi from the North Sea. Newcastle is the most populous city in the North East, and forms the core of the Tyneside conurbation, the eighth most populous urban area in the United Kingdom. Newcastle is a member of the English Core Cities Group and is a member of the Eurocities network of European cities.
Newcastle was part of the county of Northumberland until 1400, when it became a county of itself, a status it retained until becoming part of Tyne and Wear in 1974. The regional nickname and dialect for people from Newcastle and the surrounding area is Geordie. Newcastle also houses Newcastle University, a member of the Russell Group, as well as Northumbria University.
The city developed around the Roman settlement Pons Aelius and was named after the castle built in 1080 by Robert Curthose, William the Conqueror's eldest son. The city grew as an important centre for the wool trade in the 14th century, and later became a major coal mining area.
