English: The River Severn (Welsh: Afon Hafren) is the longest British river, at 354 kilometres (219 miles) long; it rises at an altitude of 610 metres on Plynlimon near Llanidloes, in the Cambrian Mountains, Mid Wales, and it passes through a number of English counties, with the county towns of Shrewsbury, Worcester, and Gloucester located on its banks. The Severn becomes the Bristol Channel at its estuary, eventually discharging into the Irish Sea and the Atlantic Ocean.
