In contrast, the manor of Pachesham became fragmented as the Middle Ages progressed. By the time of Domesday book, it was already divided into two parts, the smaller of which was later referred to as 'Pachenesham Parva'. No written record of either part of the manor survives from the subsequent 200 years, but in 1286 land was recorded as passing to Eustace de Hacche. De Haache rebuilt the manor house in around 1293, which he enclosed with a moat. Excavations of the manor house site (now known as The Mounts) in the mid-20th century, provided evidence of several medieval buildings, including a hall, a chapel and a probable stable block. The value of the manor appears to have declined in the mid-14th century and in 1386, it was let to William Wimbledon for an annual sum of £20. In 1393, one year after a serious fire had destroyed much of Leatherhead, Wimbledon defaulted on the rent and was accused of dismantling several of the manor buildings. From the start of the 15th century, the manor land was divided between twelve lessees and then disappears from the historical record.
