The 19th Century
The Park landscape reached maturity in the early 19th Century as recorded by the artist John Nash in 1808.
Shortly afterwards Lord Bolingbroke exchanged portions of land with the church to enable the removal of the parsonage and its grounds which stood close to the house. In 1830 the old service wing was demolished, a new wing was built to replace it, and the current drive to the church created.
Due to a steady decline in the St. John family fortunes Lydiard Park became increasingly neglected during the 19th Century. For much of the century it was let to tenants and on the death of the 5th Viscount Bolingbroke in 1899 the estate was heavily mortgaged.
