Old Hall The site of the house has been a family seat of the Cholmondeley family since the 12th century. In the 16th century the house was a
timber-framed hall standing on a moated platform. During the
English Civil War in the following century, the house and its separate chapel were damaged by the
Parliamentarians and were subsequently repaired by
Robert Cholmondeley, 1st Earl of Leinster. In 1701
Hugh Cholmondeley, 1st Earl of Cholmondeley commissioned William Smith of
Warwick to encase the house with brick and to add features such as giant columns and
balustraded
parapets with urns and statues. By 1712 the earl had lost patience with Smith and asked
John Vanbrugh to prepare a new design, but it was never executed. In 1722 wrought iron gates and railings made by Robert Bakewell were used to enclose the forecourt of the house. In the 18th century the house was neglected. In 1770 it was inherited by George Cholmondeley, the 4th Earl of Cholmondeley, who decided to demolish most of the Old Hall and to replace it with a new building.
Present house Building of the new house in the style of a castle began in 1801. It was designed mainly by the Earl in collaboration with the architect William Turner of
Whitchurch, Shropshire. The design was symmetrical; the entrance front facing west and consisting of two
castellated blocks, between which was a single-storey
loggia. Behind the loggia was the full-height entrance hall. Facing the park on the east side of the house were the three main state rooms. This phase of building the house was completed in 1805. Much of the construction material was recycled from the old house, including bricks, glass, windows, woodwork and chimneypieces. Bakewell's railings, without the gates, were moved to form a screen on the main drive. In 1817 George Cholmondeley (now the 1st Marquess) started a series of enlargements to the house beginning with a new dining room. Two years later, a family wing with tall rectangular tower was added to the south of the house; both of these additions were designed by the Marquess. They were followed by the addition of two octagonal angle turrets. The Marquess died in 1828 and soon after that, Robert Smirke was commissioned to make further additions and alterations. The main addition was a round tower at the southeast corner of the family wing. Smirke also brought forward the central tower of the east front by adding a
canted bay, giving the house its present appearance. This work was completed in 1829.
Later history In common with many other country estates and stately homes, special roles were allocated to Cholmondeley during the
Second World War. Between July and October 1940 the grounds were the home of troops serving the
Czechoslovak government-in-exile. Later they were used in the preparations for
Operation Anthropoid, an assassination attempt on
Reinhard Heydrich. Cholmondeley was also employed as a Royal Naval Auxiliary Hospital which treated serving servicemen suffering from severe nervous conditions. The house was designated a Grade II* listed building on 10 June 1952. Until her death in November 2015, Cholmondeley Castle was occupied by his mother, Lavinia. ==Architecture==
