Penrith is a market town and unparished area in the county of Cumbria, England. It is in the Eden Valley, just north of The River Eamont, and lies less than 3 miles (5km) outside the boundaries of the Lake District National Park. Other local rivers bounding the town are the River Lowther and the River Petteril. A partially man-made watercourse, known as Thacka Beck, flowing through the centre of the town, connects the Rivers Petteril and Eamont. For many centuries, the Beck provided the town with its main water supply.
