The River Plym is a river in Devon, England. Its source is some 450m (about 1500 ft) above sea level on Dartmoor, in an upland marshy area called Plym Head. From the upper reaches which contain antiquities and mining remains the river flows roughly southwest and enters the sea near (and gives its name) to the city of Plymouth, where the settlement was historically known as Sutton. Its tidal estuary is known as the Laira. It is approximately 30 km (about 20 mi) long.
The name Plym is thought to have its origins in Old English and means the 'plum tree', from a back-formation from the name of Plympton.
HMS Plym (K271), a River-class antisubmarine frigate, was named after the river during World War II. It carried out convoy escort duties in the North Atlantic and was later destroyed in the UK's first nuclear explosion.
When it was in operation, the Cann Quarry Canal left the river at Marsh Mills.
The Plym Valley Railway is a volunteer run railway which operates steam and diesel hauled train rides along a section of the Plym Valley from Marsh Mills station. The railway is currently extending its line to Plymbridge.
Famous quotes containing the word river:
“Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.”
—Henry David Thoreau (1817–1862)
