Secklow Mound, the moot mound of Sigelai Hundred, has been found, excavated and reconstructed: it is on the highest land in the central area and is just behind the Central Library in modern Central Milton Keynes. Only one medieval manor house survives: the 15th century Manor Farmhouse in Loughton. There are sites of other manor houses in Little Woolstone, Milton Keynes village, and Woughton on the Green. The oldest surviving domestic building is Number 22, Milton Keynes (village), the house of the bailiff of the manor of Bradwell.
