Berwick-upon-Tweed is a town in Northumberland, England, located on the northernmost edge of the country near the border with Scotland. It lies at the mouth of the River Tweed and has a long history of conflict between England and Scotland, having changed hands multiple times before permanently becoming part of England in 1482.

The town is known for its well-preserved Elizabethan town walls, built to defend against Scottish attacks. Other historical landmarks include Berwick Castle, which is now largely ruined, and the Berwick Barracks, which house museums relating to the town’s military history. The Royal Border Bridge, completed in 1850, spans the River Tweed and serves as an important railway crossing.

Berwick-upon-Tweed has a working harbour and a small fishing industry, though tourism plays a significant role in the local economy. The town’s coastal location provides access to beaches and scenic walks, including parts of the Northumberland Coast Path.

Berwick is also home to Berwick Rangers Football Club, which is unusual in that it plays in the Scottish football league system despite being based in England. The town has a mix of architectural styles, reflecting its varied history, and retains a distinctive character shaped by its border location.
