The Tarr Steps are a clapper bridge across the River Barle in the Exmoor National Park, Somerset, England.〔(【引用サイトリンク】 work=Images of England )〕 They are located in a national nature reserve about south east of Withypool and 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 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. The bridge has now been re-assembled〔 ==Nature Reserve== Owned by Exmoor National Park Authority, Tarr Steps Woodland National Nature Reserve covers 33 hectares of the River Barle valley.〔(【引用サイトリンク】title=Tarr Steps Woodland NNR )〕 This is mainly Sessile Oak (''Quercus petraea'') woodland, with beech (Fagus), ash, sycamore (''Acer pseudoplatanus''), hazel (''Corylus''), blackberry (''Rubus''), bluebells (''Hyacinthoides non-scripta'') and honeysuckle (''Lonicera''). It is internationally significant〔(【引用サイトリンク】title=Tarr Steps and the Exmoor National Park )〕 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 to a footbridge and returning on the other side, crossing the river on the clapper bridge. The main car park and toilets (some 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tarr Steps」の詳細全文を読む スポンサード リンク
