Telford is a large new town in the borough of Telford and Wrekin and ceremonial county of Shropshire, England, approximately 13 miles (21 km) east of Shrewsbury, and 30 miles (48 km) west of Birmingham. With an estimated population of 162,300 in 2009, Telford is by far the largest town in Shropshire, and one of the fastest growing towns in the United Kingdom. Telford now includes Ironbridge Gorge, a scenic tourist destination and UNESCO World Heritage Site. The town advertises itself as "The Birthplace of Industry", due to its proximity to Coalbrookdale and other places in the Ironbridge Gorge area, which are internationally recognised as being important to the Industrial Revolution, and being to a large extent constructed on the Shropshire Coalfield. The River Severn flows along its southernmost boundary.
