In 1997 Waverley Borough Council, the landowner, commissioned a preliminary survey into the historical and archaeological background of the land that forms the New or Little Park (now Farnham Park), just to the north east of the town of Farnham, in Surrey. The Park, which is a public open space, has been the site of a number of finds of important antiquities in recent years. As a result the Council felt that, for management purposes, it would be prudent to establish the range and degree of survival of historic landscape features and of archaeological sites within the boundaries.
Trial trenching in fields at Frensham Manor in 2001 located a Roman occupation site which survives below plough soil level and would appear to represent the remains of a small farmstead dating from the late 1st to the 3rd centuries AD. Finds of redeposited fragments of highly fired clay flooring point to the presence of a kiln in the immediate vicinity and metal detector finds from adjacent fields are indicative of further Roman activity in the area.
The West Lodge building(s) is to the east side of Blacksmith Lane at the west (main) entrance to the Chilworth Gunpowder Mills Middle Works site originally serving as an entry control point.
Following closer inspection in August 2016 it became apparent that the building had not been extended, but rather later connected to an independent closely adjacent building of two rooms by the insertion of a link structure.
