Walland Marsh is a part of Romney Marsh, mostly in Kent with part in East Sussex. The name means ''wall-land'': its north-eastern border, separating it from the rest of Romney Marsh, is the Rhee Wall.〔(Romney Marsh: The Fifth Continent ) Rye Castle Museum, accessed 4 Nov 2014.〕 The Rhee Wall is 7.5 miles long and runs from Appledore, through Brenzett and Old Romney to New Romney; it consists of two parallel earth banks, from 50 to 100 metres apart, the ground between being raised above the marsh on either side. It was built in the 13th century, as a watercourse to wash away silt from the harbour at New Romney. The plan eventually failed; the Rhee Wall has not contained water since medieval times.〔〔(History of Romney Marsh ) The Romney Marsh.net, accessed 4 Nov 2014.〕 Walland Marsh is bordered in the south-east by Lydd (beyond which is Denge Marsh) and in the south-west by Rye. The villages of Fairfield, Brookland and East Guldeford are within the region.〔One-inch map of Great Britain: Sheet 184, Hastings. Ordnance Survey, 1969.〕 The marsh was turned into productive farm land in past centuries. The land of Walland Marsh was reclaimed mostly from the 13th to 15th century, later than that of Romney Marsh to the north-east. The reclamation was done in stages by creating ''innings'': an embankment was built round an area of marsh, which would drain at low tide.〔 To retain the productive land, drainage channels, known locally as sewers, were created. A notable example is White Kemp Sewer, which runs across the centre of the marsh, and flows into Jury's Gap Sewer; this leads to the coast at Jury's Gap, near Camber Sands.〔〔 ==References== 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「Walland Marsh」の詳細全文を読む スポンサード リンク
