Foundations believed to be of a house that predated the iconic Mansion have been found as part of the £8 million, Heritage Lottery Funded restoration of Bletchley Park.
Water Hall was built in 1711 but by the late 18th century it had fallen into disrepair and was demolished by 1806.
English Heritage’s 2004 report on the historic value and importance of Bletchley Park says: “The mansion was the third significant house to be built in this part of the estate. A farmhouse existed in the vicinity of Water Hall in 1780; this was probably the same farmhouse that stood to the north-west of the Water Hall site as late as 1871. Together with its outbuildings (a dairy and stables), it would have been demolished prior to the construction of the present mansion. It seems to have stood on the site now occupied by a lawn, to the south of Hut 4. Contrary to some accounts, none of its structure was incorporated within the mansion.”
