The Tarr Steps are a 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 two tons each. 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 and Scheduled Ancient Monument.
Half of the bridge was washed away by the river whilst heavily swollen by rain in December 2012 and was re-assembled. It was damaged again in November 2016 and will, according to Somerset County Council be rebuilt again.
