Tarr Steps
Encyclopedia
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 and Scheduled Ancient Monument
.
covers 33 hectares of the River Barle valley. This is mainly Sessile Oak
(Quercus petraea) woodland, with beech
(Fagus), ash
, sycamore (Acer pseudoplatanus), hazel
(Corylus), blackberry
(Eubatus), bluebells
(Hyacinthoides non-scripta) and honeysuckle
(Lonicera). It is internationally significant for the mosses, liverworts and lichens which flourish in the cool damp conditions. Much of the woodland was once coppiced, primarily to provide charcoal for the local iron
smelting industry. The river and the valley woodlands are part of the Barle Valley
Site of Special Scientific Interest
and abound with wildlife, ranging from red deer
to dormice, including the rare Barbastelle Bat (Barbastella barbastellus) and otter
that feed along the unpolluted and fast-flowing river.
Well marked footpaths run along the valley between Simonsbath
and Dulverton
and to the village of Withypool
. There is a circular walk from the main car park for Tarr Steps down to the river, along the riverbank for about 1.3 kilometre (0.807784557644749 mi) to a footbridge and returning on the other side, crossing the river on the clapper bridge. The main car park and toilets (some 400 metres (1,312 ft) from the bridge via a footpath) can be reached from the B3223 road between Withypool and Dulverton. Parking for the disabled and refreshments are available nearer the bridge, as are information panels put up by the Exmoor National Park, giving details of Tarr Steps history and design.
"claperius" which means "pile of stones". It is an ancient form of bridge constructed with large unmortared slabs of stone resting on one another; this is the largest example of its type. There are 17 spans across 50 metres (55 yd), the top slabs weigh 1-2 tons and are about 39 inches (99.1 cm) above normal water level. The largest slab is over 8 feet (2.4 m) long and is about 5 feet (1.5 m) wide. This is one of the best known monuments on Exmoor. Its age is unknown, as several theories claim that Tarr Steps dates from the Bronze Age
but others date them from around 1400 AD. It has been restored several times in recent years, following flood damage. Over the years the damage provides a good indicator of the strength of each flood. Some of the top slabs have been washed away in extreme flood conditions and they have now all been numbered to facilitate replacement. The Exmoor National Park web site says
“The stones forming the spans weigh between one and two tons each and have on occasions been washed up to 50 yards (45.7 m) downstream. A distinctive feature of Tarr Steps is the slabs that are raked against the ends of each pier to break the force of the river and divert floating debris. Despite this, much of the damage has been due to debris such as branches floating down with the flood and battering the bridge. Debris used to be removed once a year by farmers from the Dulverton and Hawkridge sides of the river but since the flood of 1952 it has been trapped by cables strung across the river upstream of the bridge".
Older locals can remember deer walking under the spans of the bridge. The stags would jump over and the hinds walk under. Now the spans only clear the river bed by about three feet, suggesting that there has been silting of the river bed and that the river does not have to rise as much to overtop the bridge.”
