A Valley Grows Up is a history book for children, written and illustrated by Edward Osmond and published by Oxford University Press in 1953. It features an imaginary English valley over the course of seven thousand years, from 5000 BCE to 1900. Osmond won the annual Carnegie Medal, recognising the year's best children's book by a British subject. In more than seventy years only a handful of nonfiction books have been so honoured.
