PRN 55328 Originally perhaps a mid-Georgian house, it was recased and stuccoed in the 1830s. The result was a rather severe looking block, three storeys high, four by five bays, with projecting ground floor window bays on the south front. In the 1790s this front had a pediment, but it was removed when the house was altered. The house was always intimately connected with the history of Gainsborough. Lord Burgh sold the manor of Gainsborough in 1586 to Sir William Hickman. His descendant Sir Willoughby Hickman bought the Thonock estate, moved out of Gainsborough Old Hall and was a great opponent of James II. He died in 1720. The hall and its associated gardens were probably constructed after 1720 under the direction of Sir Neville George Hickman. When Sir Neville George Hickman died in 1781 their baronetcy became extinct. The estate eventually passed on to Henry Bacon, youngest son of Sir Edmund Bacon of Raveningham Hall, Norfolk in 1827. It was probably around this time that the hall was altered. The estate passed through a number of hands until it became the seat of Sir Hickman Bacon, Premier Bareonet of England until his death in 1945. His nephew Sir Edmund Bacon, KG, having already Raveningham Hall in Norfolk, was daunted by Thonock, used only the agent's house at Gainsborough. The house was closed and used as stores. Dry rot and woodworm did their worst. The house, which never had gas or electricity installed, had no bathrooms and only paraffin lamps for lighting. The house was eventually demolished in 1964. {1}{2} A range of outbuildings and structures are depicted on Ordnance Survey maps. A former ice-house (now demolished) can be seen at TF83019214. The ice-house is depicted as a mound on the Ordnance Survey County Series map of 1905. Part of a stable-block adjoining the main house (at TF83069201) still remains, as does a rectangular walled garden (TF83129212). The lodges to Thonock Hall still remain; the west lodge (TF82049129) now forms part of a golf club, and the east lodge (TF83229083) which is in private ownership. Much of the lanscape garden remains, including the ornamental lake, which has been incorporated into a golf course.{3}{4}
