One of the seven hundred plus people who saw the trial excavations over the weekend was called George. He was short, blonde, four years old and full of lots of clear, penetrating, questions. After we had dispensed with “Why do you have a bucket?” and its natural follow up “Why do you have another bucket?” he Paxman-like moved to the killer blow. “Why are you doing this?”
Excellent question and not the easiest to answer simply.
There is the pragmatic answer: we want to improve the drainage here, and want to be sure that we don’t damage any archaeology. But its not the full answer. There’s a big dollop of curiosity to see a building we’ve known about for years but none of us have ever seen, too. And then there’s the bigger picture, learning more about how the gardens at Studley developed, so that we understand them better. George didn’t look entirely (or, to be honest, even slightly) convinced. He could see it was really a first class excuse to play with “boy toys” like the mini-digger, as he eyed it keenly over my shoulder. O.K, I admitted, so there’s probably a bit of that in there too…..
Yesterday did come as something of a shock. Before setting out to dig one tries to understand the “site formation model”. That’s the way in which archaeological remains are likely to have been formed, what they are likely to look like, how deeply they are likely to be buried, and what’s likely to have happened to them after deposition. The map and illustrative depictions of the Bathhouse are all pretty consistent, leading to expectations of remains of the building within 30-40cm of the ground surface next to the present path (and that that path is unchanged from its Georgian form).
The uncertainties we sought to resolve by trial trenching were intended to be two fold. Firstly, it wasn’t clear what sort of masonry remains we’d find. Depending on what the demolition men were told to do, we might find the bases of walls (or even floors) left in situ, or failing that clear foundation trenches cut into the substrate and filled with rubble. What was likely to survive would in part depend on how the lower part of the building was constructed (illustrations show it approached up steps, so the floors would have been above contemporary ground level). Secondly, as there was no clear horizontal platform on the valley side where the building had been sited, we could be certain there would be deposits of landscaping materials put in place to blend its site into the natural slopes behind. We didn’t know how deep these would be – a matter of small interest in terms of the history of the garden, but of much greater interest for planning the August excavations. It’s a tight site, and we need to plan for the size and location of spoil heaps.
Against such a reasonably predictable site formation model, the discovery of deep stratigraphy right across the site came as a considerable surprize. But by close of play on Sunday, a reasonably coherent story had emerged. It was really useful to extend the trench south towards the present path early in the day. The direct physical relationships between the path and the substrates were obscured/destroyed by an early-modern drain (which had undergone several episodes of failure and repair), but there was no sign of natural substrate rising up towards the path. This strongly suggests the rather unexpected conclusion that the path’s height has been raised. If so, then this probably occurred during the landscaping works after demolition of the bathing house.
The post-demolition landscaping layers were certainly present, and in considerable depth. We will need to plan a broad trench in August if we want to dig deeply down through these layers (which we will want to).
But the rest of the deposits we saw will need a lot more thinking about. The amount of building material – including brick, tile, slate, paving stones, floor tile, and decorative wall plaster – present, strongly suggests we are in the right location. By the end of the day on Sunday, Nicky, Justin and I were reasonably open to the possibility that the major deposit of rubble seen in the floor of the trench was perhaps filling a foundation trench at greater depth. On reflection, it was about in the position where we’d predicted the location of masonry when we’d picked the trench location in the first place.
The water-logged, smelly, clays at the same depth remain a bit of a mystery. As speculated yesterday, they might be something to do with a sub lining below the pool, but this isn’t incredibly convincing. That would only really work if all of the deposits we saw were filling a large pit, cut – perhaps - for the pool. We can test that quite easily by further trenching (at 90 degrees to the first trench) in August. On the other hand these soils could have formed under a pond fed by the spring, predating the bath house. If the ground continued to stay wet and smelly during the building’s life, then that might have contributed to its demise. It might even have been the cause for greatly raising the level of the ground surface, which we now seem to have evidence took place.
But it has to be admitted that, for the moment, the lost Bathing house remains lost. We have clear clues to follow up in August. There’s every chance that the main rubble layer in the trench floor is in a foundation, just as we predicted, and that the back of the building lies further north than we trenched. The unpredicted depths of deposits certainly raise the likelihood of extant masonry, if we can get down to the previous ground level. On the other hand the nature of the rubble we’ve seen so far suggests that building materials were carefully gathered for reuse, perhaps encouraging thorough reuse..
That drain at the southern edge of the site provided one last clue. Although it obviously postdated the re-landscaping and included lC19/eC20 building materials, it didn’t just run parallel with the path. In the west section of the trench we could see the drain spurred, with a branch heading off to the north-west away from the path and towards the suspected site of the west wing of the building. It’s hard to see what this could have been intended to drain…. except perhaps the outflow from the former plunge pool?
