Stockton-on-Tees

Stockton-on-Tees is a market town in County Durham, England, with a population of 84,815 at the 2021 UK census. It gives its name to and is the largest settlement in the wider Borough of Stockton-on-Tees. It is part of Teesside and the Tees Valley, on the northern bank of the River Tees. The River Tees was straightened in the early 19th century, so that larger ships could access the town. The ports have since relocated closer to the North Sea, and ships are no longer able to sail from the sea to the town. This is due to the building of the Tees Barrage, which was installed to manage tidal flooding. The Stockton and Darlington Railway served the port during the early part of the Industrial Revolution. The railway was also the world's first permanent steam-powered passenger railway.
