A clapper bridge is an ancient form of bridge found on the moors of Devon (Dartmoor and Exmoor) and in other upland areas of the United Kingdom including Snowdonia and Anglesey. It is formed by large flat slabs of granite or schist supported on stone piers (across rivers), or resting on the banks of streams.
