The City of Worcester, commonly known as Worcester, (i/ˈwʊstər/ WUUS-tər), is a city and county town of Worcestershire in the West Midlands of England. Worcester is situated some 30 miles (48 km) southwest of Birmingham and 29 miles (47 km) north of Gloucester, and has an approximate population of 94,000 people. The River Severn runs through the middle of the city, overlooked by the twelfth-century Worcester Cathedral. The site of the final battle of the Civil War, Worcester was where Oliver Cromwell's New Model Army defeated King Charles II's Cavaliers, cementing the English Interregnum, the eleven-year period during which England and Wales became a republic. Worcester was the home of Royal Worcester Porcelain and the birthplace of the composer Sir Edward Elgar. It houses the Lea and Perrins factory where the traditional Worcestershire Sauce is made, and is home to one of the UK's fastest growing universities, the University of Worcester.
