In my last post I mentioned how the dig that has just finished claimed that little remains of Sayes Court Manor House. What about their similar claim about the gardens?
First, a few words about garden archaeology in general. For a
long time, it was believed that the later developments of the
Landscape Movement had forever erased all traces of seventeenth century and
earlier garden layouts, hence Roy Strong’s poignant dedication in his “The
Renaissance Garden in England”, published in 1979: “In memory of all those
gardens destroyed by Capability Brown and his successors.”
Then, over the past couple of decades, along came the development of garden archaeology, thanks to which recovery and restoration were shown to be possible in many cases. Planting beds, pathways, garden buildings, tools and plant-pots, and even seeds and pollen can be found. Soil analysis can show what kind of plants were likely to have been grown in particular areas. Old parterres can survive just centimetres below the modern surface. Hampton
Court is an obvious example of such survival. Another is Castle Bromwich
Hall in the West Midlands, whose layout was remarkably well-preserved,
despite having been “double-dug” not long before, because it had been laid
down into a hard bed of compacted gravel. According to the Council for
British Archaeology’s Handbook on Garden Archaeology, this was “a common
technique in the construction of 17th and early eighteenth century parterres”.
All of which would seem to imply that careful excavation that truly set out, as the briefing note for the excavation declared, to “establish the precise location and condition” of the features should have revealed at least SOME evidence of the gardens at Sayes Court. But, along with a lingering attitude that gardens are not “proper” archaeology, specialists in this sub-discipline are few and far between. It requires a different methodology to ordinary excavation. Most importantly, machines are only supposed to be used to remove topsoil and overburden, with hand-digging of the actual features themselves. But, as Chris Currie notes in his Council for British Archaeology-published guide to good practice, “what is usually considered “overburden” on many garden sites can often be significant garden horizons”. Put bluntly, unless supervised by experts in garden archaeology, garden features can easily end up being sliced through and removed in the buckets of JCBs.
What real reassurance do we have that this isn’t, in fact, what has been happening at Sayes Court? I wrote to English Heritage, who told me that as part of the planning for the work, they had recommended that a person with an expertise in garden archaeology should be made available by Museum of London Archaeology, who conducted the work under the consultancy of CgMS Consulting Ltd for the developer. However, the Museum of London failed to reply when I asked them to confirm whether they had actually followed this advice and involved a garden archaeology expert.
The PR firm for Hutchison Whampoa (Hardhat Communications) sent me a classic piece of condescending flim-flam in response to a similar specific enquiry as to whether a garden archaeology expert had actually been engaged: “the archaeological consultant, project manager and site supervisor have between them over 65 years of professional experience”. So, I take it that’s a “no”, then.
