Pachenesham Magna, Leatherhead has been described as a probable Fortified Manor House.

There are earthwork remains.

This site is a scheduled monument protected by law.


The site of a 12th-14th Century Moated Manor House, known as 'The Mounts'. Several phases of construction of the hall and other buildings are clearly represented, from the 12th century to dereliction c. 1350 or a little earlier. Excavation in 1949 explored the area within the moat: foundations of the Hall, part of the Chapel, a well and other structural remains of buildings, erected in 1290-91 by Sir Eustace de la Hache, were recovered and planned. Much stratified pottery and a number of small objects were found, but no coins. The well, lined with flint masonry in its upper part, was only partly cleared. Foundations of square masonry pillars adjoining the well must have served in raising the water, and show that it was fitted with a counter-balanced beam apparatus. (SHHER)

The Mounts includes a levelled platform on which buildings have been shown to have stood but also the earthworks which surround the platform, these comprising a complete circuit of moat and a length of embanking on the north-east side. Although no moat is visible on the steeply sloping south-east side, an area beyond the edge of the platform is included since excavation has demonstrated that a shallow moat does survive in this area too. Moated sites are generally seen as the prestigious residences of the Lords of the manor, the moat marking the high status of the occupier but also serving to deter casual raiders and wild animals. Excavation has shown that, like most moated sites, the example in The Mounts was used in the later 13th century. It has also been shown, however, that an earlier building had occupied the site, around which the moat was dug during the 13th century. The moated site in The Mounts was short-lived: historical records show that by 1343 the manor was of little value, and by 1386 the main building had already been dismantled. The platform itself forms a rough oval in shape, and measures 45m by 30m. The slight moat on the south side has been obscured by soil creep from above, but it becomes more visible towards the north and reaches a maximum width of 21m. The unusual siting of the moat leaves a natural outer bank which is enhanced on the north-east side by an additional earthen bank 25m long and 4m wide. (Scheduling Report)

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
