Roman remains and the large Mildenhall Hoard of coins have been found two miles to the east of Marlborough, at Mildenhall (Cunetio). A later Saxon settlement grew up around The Green and two early river crossings were made at Isbury Lane and Stonebridge Lane. In 1067 William the Conqueror assumed control of the Marlborough area and set about building a wooden motte-and-bailey castle, sited on the prehistoric mound. This was completed in around 1100. Stone was used to strengthen the castle in around 1175. The first written record of Marlborough dates from the Domesday Book in 1087. William also established a mint in Marlborough, which coined the William I and the early William II silver pennies. The coins display the name of the town as Maerlebi or Maerleber. He also established the neighbouring Savernake Forest as a favourite royal hunting ground and Marlborough castle became a Royal residence. Henry I observed Easter here in 1110. Henry II stayed at Marlborough castle in talks with the King of Scotland. His son, Richard I (“Coeur de Lion”) gave the castle to his brother John, in 1186. King John was married here and spent time in Marlborough, where he established a Treasury.
