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. According to the Dartmoor National Park, the word 'clapper' derives from an Anglo-Saxon word, 'cleaca', meaning 'bridging the stepping stones'. Although often believed to be of prehistoric origin, most were erected in medieval times, and some in later centuries. They are often situated close to a ford where carts could cross. A packhorse is a horse used as a pack animal, the most often used method of transporting goods across Dartmoor for many years.
