Abbot's Wall is a seawall probably built by the Abbot of St Augustine along the River Stour to prevent the sea flooding the Minster marshes. The precise date of its construction is uncertain. A document from 1293 concerning the blocking of a creek at Minster twenty years previously is thought to be a related incident. The wall comprises an earthen sea bank and an inner drainage ditch, in places a berm also seperates these sections. A number of contemporary sluices are cut into the bank along its length. The feature extends for approximately 7 kilometres from just to the south of Monkton to near Richborough Port. Most of the wall is in good condition except for the final kilometre which has been destroyed.
