Watch Deep Roots, Dark Earth: Freemining in the Forest of Dean (1970) : Full Movie Online Free For centuries, freeminers have held the right to mine coal anywhere within the Forest of Dean. To become a freeminer, one must be over 21, born within the hundred of St Briavels, and have worked underground for a year and a day. Today, Forestry England administers the mining tradition, with only a few freeminers still venturing underground in search of the elusive ‘black gold,’ helping to keep this unique heritage alive. This short documentary offers a rare glimpse into the lives of those most connected to this fascinating practice. Through their eyes, we explore the dark depths beneath the ancient forest floor and uncover an enduring way of life.
