Digging In to Garden History

For the past five weeks, one day each week, I made the journey to Fulham Palace in west London to take part in their community garden archaeology dig. I had never been to Fulham Palace - let alone heard of it, shame on me - before I read about the dig and it needed only a second to decide to sign up. I figured I'd go the first day and see how I liked it before committing more time. Little did I know I'd get hooked.

There have been settlements at the site of Fulham Palace since the Iron Age and evidence of Roman occupation has been found nearby. There has been a palace here since, oh, 704 AD, and it was the residence of the Bishop of London until 1973. Bishops were pretty high up in the social, political, and religious echelons so it wasn't unusual for a Bishop to have several houses with a tally of 177 homes for 21 bishops in the 16th century.

Each successive bishop who lived at Fulham left his mark of improvement on the house and gardens, now a listed historical site by English Heritage. Elizabeth I was sent gifts of grapes from Fulham Palace's famous gardens, and one botanically enterprising bishop in the 17th century received rare species of plants from one of his American missionaries, himself a trained botanist. Among the exotics collected at Fulham Palace was a magnolia tree, the first to be grown in Europe.

In the late 1700s a two-acre walled kitchen garden was enclosed when the grounds were remodelled. The current entrance to the walled garden is through a Tudor gateway (and boy, were people short then or what?). There was a vinery, a knot garden was laid out in the 19th century, and fruit trees, espaliers, and loads of herbs and veg grown in the traditional four-quarter garden. Flowers for the house were also grown along the path borders and in the glasshouses.

During the Second World War, part of the palace grounds were used for allotments, a use which still continues today. Luckily, the palace was spared bomb damage but bombs did fall in the allotments and kitchen garden (so the archaeological health and safety brief that included what to do if we uncovered any unexploded ordnance was no joke).

Fast forward a few hundred years to the 20th century when the palace had fallen into a state of decay and neglect. The area surrounding the palace, including a medieval moat, was designated a Scheduled Ancient Monument in 1976 and it took the next 30 years for committees to come to agreement on the restoration. A grant from the Heritage Lottery Fund enabled restoration of the building in 2006 and a subsequent grant in 2010 allowed for restoration of the gardens and grounds.

Included in this work was the excavation of the ancient moat, originally over a mile in length, that surrounded the site. The moat will filled in back in the 1920s and loads of builders' debris was chucked in. Only one section of the moat has been uncovered and restored, including the moat bridge, so far but there are hopes to eventually excavate the entire circuit.

But now the for the fun part. The walled garden dig! Part of the restoration scheme includes an archaeological investigation of the walled garden to attempt to find evidence of planting or building features to aid in determining the appearance and planting in the garden which will, in turn, inform the restoration to a fully functioning kitchen garden. One of the first features to be uncovered and restored were the bee boles on the north-west face of the wall. Bee boles are little niches built into a wall to protect bee hives and their industrial inhabitants. Facing what was the original kitchen garden area, they were bricked in at some point, possibly when the kitchen garden was moved, but have now been de-bricked and will hopefully house bee hives again soon.

The actual digging took place in two trenches - logically referred to as Trench A and Trench B. Each area measured 25m square, and was divided in to a 5m grid. The top soil was removed by machine and the layers beneath excavated by hoe and trowel. Changes in the soil color and composition indicate the presence of features - planting holes, post holes, tree boles, etc - so these were excavated and recorded before uncovering the following layer.

The work was slow, tedious, and painful (lots of protesting from knees and back) but also really, really interesting. Volunteers cheerily asked with astonishing regularity, "Find anything interesting?" and when we did, a little thrill went through the camp. Maybe one of us would find some Roman hoard or the base of an old fountain. Given that the area had been a kitchen garden, and fields before that, we knew we weren't going to find any lost civilisation but one of the archaeologists had been involved in the discovery of the 18th c. pebble mosaic orangery floor at Chiswick, so you just never know.

In the end, we found lots of potsherds, bits of broken china, and my new obsession, clay pipes and stems. All these things help to date the feature so all the finds are collected in bags and tagged with numbers matching the feature being excavated. The oldest finds at this dig included some Roman pottery, so that's exciting. One feature that I excavated had some pieces of wood rotting in it but we knew the wood was modern because it had been painted. My theory was that it was a tree stake but who really knows?

One of my features - two different fills are present, as are two pieces of wood (barely visible on the far left of the profile), possibly tree stakes?

Some features were small and shallow, some were really huge and astonishingly deep. The soil here is sandy and very free draining so clay was mixed in with the fill to help retain moisture for whatever plant went into the hole. The differences in soil composition was pretty clear once you knew what to look for (and gave me flashbacks to soil science class). Fill soil (that which is different than the surrounding soil that was dug into, which is called the 'cut') is saved for analysis and they hope to find some seeds that might indicate what was planted here. This will help them further narrow down the date of the feature as well as help create a planting plan from that era so the gardeners know what was planted here and how well it thrived.

In the end, the dig went back about 250 years to the "post medieval layer" which can be roughly translated to early 1700s. To dig deeper would have required more time and a lot more money than the budget allowed but it would be really interesting to see what, if anything, was to be found at the Roman layer.

Three archaeologists were on site during the dig, and all of them were wonderfully patient with us volunteers. The other volunteers, likewise, were a very able and willing bunch with several going to the dig every day or several times a week. The dig was a great way to get the community involved in the project, was a fantastic hands-on tool for teaching school kids about history, and it attracted so many interesting people - a professor in ancient Greek history, an English tutor, a horticulturist, an archaeology student, a garden historian (!), and so many others with such fascinating backgrounds. All were so enthusiastic about the dig that on the last day when we met for drinks down at the pub at the end of the day, we were all equally sad to see it end. I propose a volunteer reunion in a year's time to see how the rest of the garden restoration is getting on. Of course, most of the volunteers are local so they can visit any time, but I'll have to wait a year or more before I'm able to get back.

After learning how to look for features, clean the surface, excavate, record (by drawing and photographing), taking levels and applying what I know of garden history to what was found at the site, I'm convinced that garden archaeology has a very important place in the field of historic garden study. Not only does it give a more complete picture of what occupied the site in previous centuries, but it completes the picture that paper documentation (if there is any) leaves unfinished. While it would be fantastic to jump in a Tardis and see the actual garden as it was 250 years ago, I think the thrill of discovery that archaeology brings would be lost.

So what's next now that the dig is finished? The trenches are being filled back in as I type, and all the written records and drawings will be compiled into a computer generated (CAD) plan of the site. All the scientific data is compiled and a written report is done, then the whole bundle handed over to the people in charge. Based on the final outcome, a new plan of the garden will be designed based on historic information from the dig. The whole process will take another couple of years but the gardeners hope to have the first bit of the garden redesigned and replanted in the very near future, adding a new layer to the history of this ancient site.

Fulham Palace is located in Fulham, SW London. The nearest tube station is Putney Bridge and a pleasant 10 minute walk along the Thames Path will take you directly to the palace. The grounds are open free of charge from dawn till dusk. The walled garden and palace have different opening times so check the palace website for details. There is also a very nice cafe open daily from 9 to 5.

*A special thanks to Eleanor Sier, Fulham's Learning Officer, for organizing the volunteers and keeping us well fortified with tea and biscuits, and for making the dig such an enjoyable experience!

Take Me Thence, Country Roads

A man called Oliver Goldsmith once said, "life is a journey that must be traveled no matter how bad the roads and accommodations." I bet he was a riot at parties. I can just imagine him and Robert Frost going at it: "Tell me, Ollie, If your road diverged in a yellow wood, which path would you choose?"

I've come to realize that my dissertation could just as easily be about travel as it is about gardens. After all, the gardens I'm studying are spread throughout England and were created over 300 years ago. One had to get to them somehow and in our age of easy travel, we can't truly know what an undertaking it was to venture even 20 miles back then. I was contemplating this fact when Knightly came to mind. You know, the hero of Jane Austen's Emma:


*sniff* Makes me cry every time! I mean, he rode through the rain! To us, spoiled as we are by cars, motorbikes, and busses zipping around on macadam*, that means nothing. So he rode through the rain. Big deal! He got a little wet; so what? So what!? Oh, my dear, I despair of you! Permit me to recall another Austen character, Edward, who, upon returning to Barton Cottage to profess his undying love for Eleanor and, with understandable awkwardness at the beginning of their meeting, satisfies the youngest sister's inquiries by informing them that "the roads were very dry". Travel, my dear, was a very big deal back then!

All these Austen shenanigans happened a hundred years after my heroine traveled around England, logging 1,045 miles in 1697, of which she 'did not go above a hundred in the Coach', meaning she rode a horse. Sidesaddle. Imagine! The state of the roads was major news, no doubt much talked of at all the inns and health spas, and the state of them was appalling, if you must know. Even by the time Edward and Knightly were riding to their fates, roads were perilous. Only city streets were paved with cobbles (well, some cities), and the country roads were sometimes 'pitched' with stones dug up from an obliging field*. Most were dirt tracks seldom maintained, so if you were traveling by coach on a road in an area known for heavy clay soil, in the rain, say, the coach wheels would leave deep ruts that dried into hard ridges, making the roads even worse. In a time when mineral and coal mining were major industries, it wasn't uncommon to encounter an uncovered pit in the road which could swallow your horse (and you with it). And if you lived in a marshy area, roads could be rendered non-existent in a heavy rain or flood. Often times you had to hire a local guide if you were travelling abroad (which in the early 1700's could be defined as anywhere outside a 5 mile radius from your home) because the roads were so bad - or so hard to find - that you could end up hopelessly lost. Or hopelessly dead. Which is why you should be greatly impressed that Knightly rode through the rain.

Look, I'll show you:
surrey soil_edited-1


This is a soil map of Surrey, where most of the action in Emma takes place (yes, I'm a geek, now pay attention). Notice that the predominant soil texture is 'loamy' and the profile indicates 'slow permeable, seasonably wet, acid loams and clays'. Good stuff for the garden, to be sure, not so good for the roads because, as the chart shows, drainage is bad. I think it's safe to say that in Jane Austen's day, when it rained, the roads in Surrey either flooded or became a muddy mess. Rivulets could create small canyons in the road if it wasn't well pitched, and if it flooded enough the stones could have been lifted right off the road leaving a gaping hole masked by muddy water which is what happened to my heroine Celia Fiennes as she travelled the roads in Cornwall:

"Here Indeed I met with...more lanes and a deeper clay road, which by the raine the night before had made it very dirty and full of water; in many places in the road there are many holes and sloughs where ever there is clay ground, and when by raines they are filled with water its difficult to shun Danger; here my horse was quite down in one of these holes full of water but by the good hand of God's Providence which has allwayes been with me ever a present help in tyme of need, for giving him a good strap he flounc'd up againe, tho' he had gotten quite down his head and all, yet did retrieve his feete and gott cleer off the place with me on his back."

Knightly could have lamed his horse*! Or met with highwaymen - ohmygosh, I haven't even mentioned highwaymen! It wasn't just a matter of trotting through a spring shower and getting his cravat a little damp, he could have met with major mishap and perilous threats to life and limb! By riding so recklessly to his beloved, he was risking his life for the mere hope of a chance to win her. This is serious stuff! Oh, that a man would ride through the rain for me!

Kind of puts a whole new spin on the story, doesn't it? History is so cool that way; it doesn't just tell you how things were then, it throws new light on what you're interested in now. And it makes me rather grateful that the only real issue I have upon commencing my garden tour this spring is deciding whether to go by car or train.

But I have to ask: if you came to a fork in the road*, would you take it?

*mac·ad·am: /məˈkadəm/

Noun:
  1. Broken stone, bound with tar or bitumen, used for surfacing roads.
  2. A stretch of road with such a surface.
*Bonus points if you caught the other two Jane Austen references and can name the movie from which they come.

*Yogi Berra said it first.
