|Shropshire is a county in the West Midlands of England. It borders Powys and Wrexham in Wales to the west and north-west, Cheshire to the north, Staffordshire to the east, Worcestershire to the south-east and Herefordshire to the south. The county's population and economy is centred on five towns: the county town of Shrewsbury, which is culturally and historically important and is located close to the centre of the county; Telford, a new town in the east which was constructed around a number of older towns, most notably Wellington, Dawley and Madeley, which is today the most populous; and Oswestry in the north-west, Bridgnorth just to the south of Telford, and Ludlow in the south. The county has many market towns, including Whitchurch in the north, Newport north-east of Telford and Market Drayton in the north-east of the county.
The Ironbridge Gorge area is a UNESCO World Heritage Site, covering Ironbridge, Coalbrookdale and a part of Madeley. There are, additionally, other notable historic industrial sites located around the county, such as at Shrewsbury, Broseley, Snailbeach and Highley as well as the Shropshire Union Canal.
The Shropshire Hills Area of Outstanding Natural Beauty covers about a quarter of the county, mainly in the south. Shropshire is one of England's most rural and sparsely populated counties, with a population density of 136/km2 (350/sq mi). The Wrekin is one of the most famous natural landmarks in the county, though the highest hills are the Clee Hills, Stiperstones and the Long Mynd. Wenlock Edge is another significant geographical and geological landmark. In the low-lying north west of the county overlapping the border with Wales is the Fenn's, Whixall and Bettisfield Mosses National Nature Reserve, one of the most important and best preserved bogs in Britain. The River Severn, Great Britain's longest river, runs through the county, exiting into Worcestershire via the Severn Valley. Shropshire is landlocked and with an area of 3,487 square kilometres (1,346 sq mi) is England's largest inland county.
