Yealmpton is a village in Devon. It is on the A379 Plymouth to Kingsbridge road and is about 8 miles (13 km) from Plymouth. It derives its name from the River Yealm that flows through the village. Yealmpton is home to a 400 year-old stone cottage, where it is said, a version of the famous rhyme Old Mother Hubbard was written by Sarah Catherine Martin. It is also the site of Kitley Caves where green marble was quarried; there is an arch of it in the British Museum.
