Vanbrugh in the Best Light: Sir John Soane’s Lecture Drawings of Blenheim Palace

– Frances Sands

The architect Sir John Vanbrugh (1664–1726) is currently enjoying a moment in the sun! 2026 marks the tercentenary of his death and a variety of activities have been organised to celebrate and reassess this most dynamic of British architects, under the banner of ‘Vanbrugh 300’, which is being coordinated by The Georgian Group.[1] Furthermore, Sir Charles Saumarez Smith published his book John Vanbrugh: The Drama of Architecture at the end of 2025 with Lund Humphries. And for the benefit of a wider public, Sir John Soane’s Museum is hosting an exhibition of the same title (4 March–28 June 2026) co-curated by Saumarez Smith himself and architect Roz Barr, with staff from Sir John Soane’s Museum. The largest gallery case within the exhibition contains three magnificent, large-scale watercolour drawings showing the façade of Blenheim Palace, produced by Soane’s architectural office, and these are the principal subject of consideration here.[2] Having established his career as an architect at Castle Howard from 1699, Vanbrugh then spent much of his efforts in 1705–10 designing and building Blenheim—his best known and most acclaimed achievement.

Eighty-nine years Vanbrugh’s junior, another great British architect, Sir John Soane—best remembered for his eponymous museum in Lincoln’s Inn Fields—was an ardent admirer of Vanbrugh’s work, even referring to him as ‘the Shakespeare of architects’.[3] At the age of 53, in 1806, Soane was elected Professor of Architecture at the Royal Academy of Arts in London. Having benefited from an RA education himself, Soane approached this task with the utmost seriousness, and composed a series of twelve lectures to be delivered at a rate of six per year over two years, detailing the history of world architecture and offering his opinions on the best and worst examples of the craft. As the Napoleonic War raged across the English Channel, it would have been impossible for Soane’s RA students to attempt a continental Grand Tour in order to peruse the architectural delights of France, Italy and beyond. So, to address this failing in their education, Soane instructed his own architectural office to create over 1,000 large-scale lecture drawings, illustrating significant buildings from across the reaches of history and geography. These would not only illustrate Soane’s words but also function as case studies of the key principles of the architectural profession. A suitable selection of these drawings would be displayed in the Great Exhibition Room at Somerset House during each of Soane’s lectures.[4] Our three drawings of Blenheim are excellent examples of Soane’s RA lecture drawings.

At the time, it was a relatively innovative idea to illustrate a lecture, and Soane had been inspired to do so by the example of Thomas Sandby (1721–98), the Professor of Architecture at the RA when Soane was a student there. But whereas Sandby produced some 128 lecture drawings, Soane’s efforts were on an entirely different scale. Without any remuneration from the RA, this extraordinary collection was produced on a purely philanthropic basis, and being far more fulsome than anything by Fischer von Erlach or others, it is generally thought to comprise the earliest attempt at a graphic history of world architecture. This masterful pedagogic drawings collection provided the RA students with the ultimate teaching aid: a Grand Tour in microcosm.[5] A great many far flung buildings are illustrated, including the Holy Sepulchre in Jerusalem, the Cave Temples of Elephanta near Mumbai, and the pyramids at Giza.[6] However, more than half of the lecture drawings depict British buildings, and a series of ten lecture drawings offer glimpses of the great buildings by Vanbrugh: Seaton Delaval; the Haymarket Theatre; Kings Weston; Grimsthorpe Castle; Castle Howard; two drawings depict Vanbrugh’s own home on Whitehall, Goose-pie House;  and three drawings show the façade of Vanbrugh’s greatest masterpiece, Blenheim Palace in full, half and low light.[7] Most of these Soane office drawings of Vanbrugh’s works can be seen in the exhibition at the Soane Museum.

The drawing showing Blenheim’s façade in full light offers an eloquent explanation of all the facets of Vanbrugh’s architectural oeuvre for which he is most celebrated.[8] The heroic scale of the building is awe-inspiringly apparent—suitably so for Britain’s national hero, the 1st Duke of Marlborough, who delivered a decisive victory as Captain-General of the allied forces fighting the French in the War of the Spanish Succession. Through the application of varied hues of wash, Soane’s drawing cleverly explores the theatrical undulations of the building—the ‘movement’ of the façade—which projects here and recedes there, resisting the typical country house recipe whereby the eye is drawn to a single principal focal point. Vanbrugh’s façades have been likened to theatrical stage sets, and with this drawing, we can fully understand that notion. And despite the great density of ornamental features in Vanbrugh’s composition, this drawing is so impressively detailed as to offer a true account of Vanbrugh’s textured exterior surface, with deep rustication, a forest of pilasters and orders, and a roofline which is prickly with sculptural additions. Blenheim is not a building for those seeking visual repose. It ripples and bristles with life.

Given the large scale of the three Blenheim drawings—each being around 125cm wide—it is perhaps surprising that Soane would suffer the expense of recreating the façade drawing at three differing light levels. However, it was exceedingly well judged. In Soane’s drawing showing Blenheim in half light, we lose the detail of the ornamental particulars, and are left with the undulations of the façade, and the massing of seemingly endless numbers of component blocks.[9] With this drawing, Soane offers us a pared-back explanation of Vanbrugh’s ‘movement’. Yet, this is pared back further with Soane’s third drawing of Blenheim in low light—as if in the moments immediately following sunset—in which we see little more than a silhouette of the building, and very shadowy fenestration.[10] Here Soane explores Vanbrugh’s massing of the building, and one begins to understand that Vanbrugh was not only a master of ‘movement’ on the vertical plane of the façade, but also on the horizontal plane of the roofline. That roofline is a work of art! It is, perhaps, abstract, but it is immeasurably architecturally accomplished, and explained here without all the ornamental fussiness for which Vanbrugh is so loudly praised.

Soane knew exactly what he was doing of course when he commissioned all three large Blenheim drawings. In his fifth RA lecture he stated:

He [Vanbrugh] possessed in an eminent degree the powers of invention. His works are full of character, and his outlines rich and varied; […] His great work is Blenheim. The style of this building is grand and majestically imposing, the whole composition analogous to the war-like genius of the mighty hero for whom it was erected. The great extent of this noble structure, the picturesque effect of its various parts, the infinite and pleasing variety, the breaks and contrasts in the different heights and masses, produce the most exquisite sensation in the scientific beholder, whether his view be distant, intermediate, or near.[11]

Despite his admiration for Blenheim, one suspects that even Soane would be astonished to know that it receives almost 1 million visitors each year. Certainly, these drawings will receive fewer visitors than that during their inclusion in the Vanbrugh exhibition at the Soane Museum, but we are thrilled to share them with an eager public, and I am reminded yet again what a privilege it is to be their custodian.
