ruins of the 12th-century Priory of St Mary's were both acquired by the National Trust in 1998. As the Thames forms the county boundary at this point, these areas now lie in Berkshire. History Runnymede's historical significance has been heavily influenced by its proximity to the Roman Road river crossing at nearby Staines-upon-Thames. The name Runnymede may be derived from the Anglo-Saxon runieg (regular meeting) and mede (mead or meadow), describing a place in the meadows used to hold regular meetings. The Witan, Witenagemot or Council of the Anglo-Saxon Kings of the 7th to 11th centuries was held from time to time at Runnymede during the reign of Alfred the Great. The Council met usually in the open air. This political organ was transformed in succeeding years, influencing the creation of England's 13th century parliament. The water-meadow at Runnymede is the most likely location at which, in 1215, King John sealed Magna Carta. The charter indicates Runnymede by name as "Ronimed. inter Windlesoram et Stanes" (between Windsor and Staines). Magna Carta affected common and constitutional law as well as political representation also affecting the development of parliament. Runnymede's association with ideals of democracy, limitation of power, equality and freedom under law has attracted placement there of monuments and commemorative symbols. The last fatal duel in England took place in 1852, on Priest Hill, a continuation of Cooper's Hill by Windsor Great Park. The National Trust land was donated in 1929 by Cara Rogers Broughton and her two sons. The American-born widow of Urban Hanlon Broughton, she was permitted by letter from George V to join her son's new peerage in tribute to her husband and this gift and be officially styled Lady Fairhaven. The gift was given in memory of Urban Broughton. At the time the New Bedford Standard-Times commented "It must be a source of gratification to all Americans, and especially to us here and in Fairhaven, that the presentation of this historic spot as public ground has been brought about by an American woman, an appropriate enough circumstance considering that the great charter underlies the USA's conception of government and human rights." Runnymede Eco Village Between 2012 and 2015, Cooper's Hill was occupied by a radical community living in self-build houses, huts, benders and tents, in the self-proclaimed "Runnymede Eco Village". Around 40 people, including a few young families, lived in a dispersed settlement throughout the 4 acres
