It formerly contained an important, early eighteenth century library which, along with valuable paintings, sculptures, and other artifacts including furniture, remained in the ownership of the 9th Earl and were largely dispersed at auction following his departure from the property; notable among these items were George Stubbs's 1768 painting "Brood Mares and Foals", a record setter for the artist at auction in 2010, the Macclesfield Psalter, numerous rare and valuable books, and personal correspondence of Sir Isaac Newton.
On account of its "fairy tale" external appearance and unmodernised interior, the castle has been used on occasion for film and television settings and is possibly best known to the outside world via that route, since it remains in private hands, no roads pass it, and it is generally not open to the public for visiting.
A further piece of apparently deliberate misinformation was a claim that "Shirburn Castle" was visited by a tutor of Dante at the end of the thirteenth century, before the present structure was known to exist; the 1802 document upon which this assertion was based was subsequently shown to be a forgery.
The land on which Shirburn resides was part owned the Norman nobleman Robert D'Oyly who accompanied William the Conqueror on his conquest of England in 1066.
Subsequently, his widow was pardoned and her late husband's lands restored; whether these included a Norman castle at Shirburn, or whether such a structure even existed in that form, has not been verified by subsequent researchers and may in fact simply reflect a desire of the then occupants to claim a more ancient origin for the castle than was actually the case; the relevant chapter of the Victoria County History notes only the previous existence of a manor (West Shirburn, which together with its counterpart at East Shirburn formed the twin manors of the district), which belonged in the 13th century to Robert de Burghfield, "likely to have been on the site" of the present castle.
A supposed account of a pre-1300 visit to a "castle" at Shirburn by Brunetto Latini, the tutor of Dante, also quoted in nineteenth century sources, was revealed as a forgery per a book published in 1948 (see relevant section of the Victoria County History, footnote 18).
[5] During the 1642–1651 English Civil War Shirburn was held by Richard Chamberlain for the King, but was surrendered to Sir Thomas Fairfax for the Parliamentarian cause in 1646, apparently without damage.
In 1716 the castle was acquired by Thomas Parker (1666–1732), Baron (later to be the first Earl) of Macclesfield and subsequently Lord Chancellor of England from 1718 to 1725,[5] the purchase price (for Shirburn plus another property, Clare manor) being £25,696 8s.
(more than £2 million in recent money); Mowl and Earnshaw, cited below, state that according to "a manuscript note made by Parker", the portion of the purchase price actually allocated to the castle exclusive of the grounds was £7,000, and that he also spent an additional £42,297 on the land needed for the park.
Emery postulates that after Thomas Parker purchased the castle in 1716, the latter's renovations probably affected more than three-quarters of the building, with the result that what stands at Shirburn today is "essentially an eighteenth-century interpretation of the medieval castle, following its original plan", although he allows that survivals from the original fourteenth-century structure include a "reasonable amount of the west range" (which would include the bulk of the main gate tower), the lower stages of two corner towers, and "possibly some ground-level walling internally", although he was unable to inspect the latter in person.
"[5] In a 1981 paper discussing the architecture of the present castle, authors Timothy Mowl and Brian Earnshaw suggest that the eighteenth-century rebuild intentionally incorporated round-arched, or neo-Norman, expressions of medievalism, "probably to assert a link with a supposed Norman foundation.
[8] Considering all of the accounts presently available, it would seem to be the case that, at a time when his contemporaries had most recently been constructing their new country houses in the English Baroque style (or even neo-medieval, in the case of Vanbrugh Castle), Parker decided to purchase an actual, habitable 14th-century castle and construct his new residence entirely within it, at the same time adding new windows to the surviving medieval walls and towers in the Georgian style.
A 1778 mezzotint by James Watson, a copy of which is now in the National Maritime Museum, shows the 2nd Earl's two astronomical assistants, Thomas Phelps and John Bartlett, at work in the observatory.
"[5] It is also apparent that the 19th century additions involved construction of extended outer sections of the north, east and south facades, which now display numerous rectangular sash windows of the Victorian style as opposed to the rounded Georgian windows of the 18th century makeover (the latter can still be seen to be present on the walls facing the internal courtyard, however, as evidenced by the aerial footage shown in the "external links" section).
Brewer from 1813, who wrote: The interior of Shirbourn Castle is disposed in a style of modern elegance and comfort, that contains no allusion to the external castellated character of the structure, with an exception of one long room fitted up as an armoury.
Within the castle are constructed both warm and cold baths, a luxury which too tardily creeps on the notice of this country, but which is one of the most desirable in which rank and affluence can indulge.
[12] One other record of a successful 19th century visit survives, in the form of Walter Money's report "A Walk to Shirburn Castle", from the Journal of the British Archaeological Association for December 1895, which describes the interior in some detail from p. 290 onwards, especially with regard to some particular items of interest in the armoury, plus an extensive list of the more important portraits and other pictures to be seen in various rooms, together with a description and illustration of a Roman sarcophagus originally found in the garden, being used as a pedestal.
The library items were prepared for a series of auctions, and were catalogued for the first time by staff from Sotheby's in 2004;[28] among the most notable items discovered were a first edition of Copernicus's 1543 landmark work "On the Revolutions of the Celestial Spheres", annotated by the celebrated 17th-century Oxford mathematician John Greaves, which sold at auction for £666,400,[29] and a unique and superbly illustrated 252-page 14th-century illuminated manuscript, the Macclesfield Psalter, now in the Fitzwilliam Museum in Cambridge.
[34] A set of 328 bound theology volumes acquired from the Macclesfield collection sale now forms part of the Kinlaw Library at Asbury University, a private Christian university in Wilmore, Kentucky, U.S.A.[35] The castle contents also included a number of fine paintings, one of which, George Stubbs's 1768 masterpiece "Brood Mares and Foals", subsequently sold at auction in 2010 for £10,121,250, a record price for the British artist.
[36] This painting was visible, in passing, on the wall in a room at the castle used for filming in the 1992 episode "Happy families" of the Inspector Morse TV series (see below).
[37][38] Earlier in 1998, an extremely fine Georgian silver wine set, the only known complete example of its era to survive, had been sold by Christies and is now in the Victoria and Albert Museum, its purchase assisted by a £750,000 grant from the National Heritage Memorial Fund.
[10][45] Two other items of cultural interest, a c.1721-22 marble sculpture of Hebe plus a second of Ganymede and the Eagle, both by the Italian sculptor Antonio Montauti, acquired by Parker circa 1723-25 and located since then at Shirburn, subsequently thought "lost" but stated in 2009 to be "the property of a lady", sold at auction for £79,250 each in 2009.
[41][46] In 2022, a fine portrait of the Second Earl by Sebastiano Conca also appeared on the market, described as "the property of a nobleman", after being "in the North Library at Shirburn Castle, Oxfordshire, and by descent to the current owner", selling at Christie's for £378,000.
[47] The contents of the early eighteenth century armoury, including items from both the Gage and Parker eras, were also sold following the 9th earl's departure.
[50] Another two items of interest from the collection were two superbly illustrated botanical albums consisting of original paintings of plants, by Mary Countess of Macclesfield (wife of the Third Earl) and her daughter Lady Elizabeth Parker, dating from the period 1756–1767; both ladies were instructed by Georg Dionysius Ehret, the pre-eminent botanical artist of the day and their paintings follow his style closely.
These were sold at auction by Maggs Bros. in 2022 for £225,000[51] and now reside in the Huntington Library in the U.S.A.[52][53] Since the departure of the 9th Earl, the castle appears to have remained largely vacant and, at that time, in need of substantial repairs (estimated as "some £2.6 million" in 2003).
[20] Subsequently, the owners have started to address this aspect, commissioning replacement of a number of sections of the roof and treatment of associated timbers, as documented by the contractors concerned.
[8] On account of its "fairy tale" appearance, romantic setting, and near-original condition Georgian/Victorian interior, the castle has been used as a film location on a number of occasions, including external, and some internal shots as the Balcombe family home in the 1992 episode "Happy Families" of the Inspector Morse TV series,[58][59] internal rooms, the gatehouse entrance and the church as Midsomer Priory for a 2011 episode "A Sacred Trust" of the Midsomer Murders TV series[60] (although exterior shots of the "priory" house feature Greys Court, another Oxfordshire location), as well as an exterior shot of Mycroft Holmes's country estate for the 2011 film Sherlock Holmes: A Game of Shadows.
[68] In the 2011 Midsomer Murders Episode "A Sacred Trust", the coat of arms of the fictitious Vertue family, Lords of the Manor and as represented in the supposedly local pub "The Vertue Arms", is constructed almost identically to that of the (real) Parker family, Earls of Macclesfield and owners of the film location for the fictitious priory at Shirburn Castle.
These include the old brewery, the old dairy, the old stores, stables, tack rooms and the like, and buildings which accommodate the generating equipment formerly used to power the batteries which in turn provided the castle with electricity.
