Tarr Steps, which is possibly Britain's longest clapper bridge (38.5 metres measured between the river banks or 58 metres if the stone causeways at each end are included), probably dates from the 15th or 16th centuries but it may be much older (Bronze Age or medieval). Local legend says that Tarr Steps was built by the devil. The Tarr part of the name may come from the word "torri" meaning "to break" and in this case referring to a rough or violent stream
The term clapper comes from the Latin "claperius" meaning "pile of stones". In a clapper bridge large unmortared stone slabs rest on one another. The stones used to build the bridge are local gritstones, probably from Pickwell Down.
Tarr Steps is made of three components:
- Clappers: stone slabs, which form the causeway
- Piers: these rest on the river bed and support the clappers
- Raking stones or catchwaters: these are placed against the piers to protect them and the clappers from the strong currents in the river by deflecting water and debris under the bridge or over it in times of flood.
