The granite slabs used in the bridge can weigh up to eight tonnes each.
The name 'clapper' is derived from the Middle English word 'cleper', meaning a pile of stones.
The bridge was specifically constructed to support the heavy weight of packhorses used in the medieval tin mining industry.
It is considered the finest example of its type in Dartmoor, where over 100 similar, smaller bridges exist.
The bridge was largely abandoned for transport purposes after the construction of the adjacent 19th-century road bridge.
The structure is part of a wider historic route that once connected the north and south moorland communities.
Postbridge Clapper Bridge is a medieval stone arch bridge situated over the East Dart River in the heart of Dartmoor National Park. Built around the 13th century, it was originally designed to allow packhorses carrying tin to cross the river. The structure consists of massive granite slabs, known as 'clappers,' resting on stone piers. It remains one of the largest and most well-preserved examples of a clapper bridge in the United Kingdom. Despite its age, the structure is still standing, though it was bypassed by a newer road bridge in the 19th century. The bridge is a designated Scheduled Ancient Monument. The surrounding landscape is characterized by open moorland and traditional Devon stone walling.
