|The Tarr Steps are a prehistoric clapper bridge across the River Barle in the Exmoor National Park, Somerset, England. They are located in a National Nature Reserve about 2.5 miles (4 km) south east of Withypool and 4 miles (6 km) north west of Dulverton.|
A typical clapper bridge construction, the bridge possibly dates to around 1000 BC. The stone slabs weigh up to 5 tons apiece. According to local legend, they were placed by the devil to win a bet. The bridge is 180 feet (55 m) long and has 17 spans. It has been designated by English Heritage as a grade I listed building.
