A clapper bridge is an ancient form of bridge found on the moors of the English West Country (Bodmin Moor, Dartmoor and Exmoor) and in other upland areas of the United Kingdom including Snowdonia and Anglesey, Cumbria, Derbyshire, Yorkshire, Lancashire, and in northern Wester Ross and north-west Sutherland in Scotland.

According to the Dartmoor National Park, the word 'clapper' derives ultimately from an Anglo-Saxon word, cleaca, meaning 'bridging the stepping stones';[4] the Oxford English Dictionary gives the intermediate Medieval Latin form clapus, claperius, "of Gaulish origin", with an initial meaning of "a pile of stones".

It was first recorded in 1380 and was built to facilitate the transportation of Dartmoor tin by pack horses to the stannary town of Tavistock.

Some larger clapper bridges, such as at Dartmeet and Bellever, have collapsed – their slabs swept away by floods, or raided for building or wall construction - and have since been rebuilt.

However, there are many other smaller examples in existence on Dartmoor and still in use, such as those at Teignhead Farm (close to Grey Wethers stone circles), Scorhill and across the Wallabrook stream.
