Welcome to the DTRG

The Dartmoor Tinworking Research Group (DTRG) is dedicated to study and preservation of Dartmoor's unique and world-class tin mining heritage.

Tin has been a valuable commodity from the Bronze Age to modern day and historical records relating its working survive from the mid 12th century to the 1970s. In the Middle Ages the wealth it generated enabled churches and substantial farmhouses to be built. Indeed, the very character of Dartmoor has in part been shaped by the tin miner, for almost every hillside or valley shows some evidence of the tinners' hand, whether a winding water channel, a large excavation, neatly arranged piles of waste or ruined mills and dressing floors.

The scale of the industry has left an interesting legacy of cultural and historic remains, impacting both the Dartmoor landscape and forming an important part of the heritage of European mining practice and trade.
