Sunderland () is a port city and metropolitan borough in Tyne and Wear, England. It is a port at the mouth of the River Wear on the North Sea, approximately 10 miles (16 km) south-east of Newcastle upon Tyne. It is the most populous settlement in the Wearside conurbation and the second-most populous settlement in North East England, after Newcastle.
The centre of the modern city is an amalgamation of three settlements founded in the Anglo-Saxon era: Monkwearmouth, on the north bank of the Wear, and Sunderland and Bishopwearmouth on the south bank. Monkwearmouth contains St Peter's Church, which was founded in 674 and formed part of Monkwearmouth–Jarrow Abbey, a significant centre of learning in the seventh and eighth centuries. Sunderland was a fishing settlement and later a port, being granted a town charter in 1179. The city traded in coal and salt, also developing shipbuilding industry in the fourteenth century and glassmaking industry in the seventeenth century.
