Using money raised by National Lottery players, The National Lottery Heritage Fund supports projects that connect people and communities with the UK’s heritage. Vanbrugh 300 is made possible with The National Lottery Heritage Fund. Thanks to National Lottery players, we have been able to develop a nationwide project that aims to broaden the awareness of Vanbrugh through special displays, free education programmes and lectures, throughout his tercentenary year in 2026.
Panel Talk: Vanbrugh's Hidden Blenheim
Wednesday 29th April, 4:30 pm to 7 pm
Donald Insall Associates Studio
12 Devonshire Street, London, W1G 7AB
This panel talk will explore Vanbrugh’s original design of Blenheim Palace and on-site findings from the current £12m conservation project.
Speakers:
- The author & historian Charles Saumarez Smith
- The client Kelly O’Driscoll, Head of Built Heritage, Blenheim Palace
- The conservation architect Edward Lewis, Practice Director, Donald Insall Associates
- Chaired by Tanvir Hasan, Director Emeritus, Donald Insall Associates
Charles, author of Vanbrugh: The Drama of Architecture, is perhaps the only person to have read the correspondence relating to Blenheim’s design and construction. In contrast, Kelly and Edward, both architects, know the building and its fabric intimately through their respective roles leading the current £12m conservation project - and are more aware than anyone of its design ambition, but also its shortcomings.
Together, Charles, Kelly and Edward will discuss historical records, assumptions, and their on-site findings. This will be explored through chronological themes, starting with Blenheim’s original design and concluding with its future needs:
- The changes to Vanbrugh’s original design
- The stonework paradoxes; fine craftmanship and compromised construction
- 19th and 20th century changes, new evidence and institutional memory loss
- Running Blenheim as a home & workplace, from the first Duchess to today
Doors open at 4:30, talk at 5:30, closes at 7pm.
