Guest post by Alice Rogers and Himani Sidhu work experience students from Knights Templar School, Baldock
We came here for work experience, and we had a great time! We have been given valuable life lessons by the beyond friendly workers at the museum. We have learnt lots about the area we have grown up in that we didn’t know prior to our visit. As part of our experience, we have been able to help with a new display, create top trumps cards, learnt how to catalogue items, went around town to promote a new exhibit and many other things.
We were asked by the museum staff to select our favourite display; we chose the suffragettes. This display includes letters to suffragettes, notably one from Christabel Pankhurst, outfits they once wore, badges and much more. It is fascinating to know that there were some of these noble people in this area.
Viewing these exhibits made us realize that there is a lot more significant history in North Herts than we were aware of. We have had an interesting and memorable time working here, an experience we will never forget.

In recent weeks, I’ve talked about using archaeology to look at landscapes, either through amassing data from different excavations or through using a museum object as a springboard to look at the bigger picture. Sometimes, though, a single feature can run for long distances, not respecting modern boundaries. Things like railways and Roman roads are good examples of things that cut across the land, more often than not starting and ending outside North Hertfordshire. Ley lines are not a good example, as they don’t exist (perhaps a subject for a future post).
There is a ditch and bank that runs across Therfield Heath for more than 1.4 km. Starting in a valley east of New Road (which runs between Baldock Road and Therfield village), it climbs the hill in a northeasterly direction before turning to a more easterly alignment at the edge of the scarp. It runs north of the barrow cemetery for 390 m before turning to the southeast, where it descends the hill towards Briary Lane and is lost in the grounds of the former Wicker Hall. Although it is undated, it is earlier than Napoleonic ploughing and some of the trackways on the heath; its relationship to the Bronze Age barrows suggests that they were already there when it was dug. In the valley bottoms, it is hidden by a layer of colluvium (soil washed downhill). All told, it is something of a mystery.
Yet more mysterious is an even longer feature, visible on aerial photographs (and Google Earth™, of course!). It runs for almost 3.5 km from near Duckpuddle Bush on New Road, north of Therfield, to just north of Hatchpen, east of the A10. Both ends of the feature simply fade out, and it was probably longer in both directions. It bears no relation to field or parish boundaries, the topography or a pre-modern field system visible on Lidar. Along its course, it crosses five low ridges and the slight valleys between them, on the southern edge of a dry valley that runs east to join the northeast flowing stream in Wardington Bottom.
On the satellite view, it crosses another long line in the landscape, which shows as an angled white stripe. This is a twentieth-century pipeline of some sort, and its whiteness comes from the chalk turned up by digging the trench. The feature we are looking at isn’t one of these, as it shows as a narrow band of generally darker material, showing that the feature results from many years of silting rather than piling the excavated material back into it and perhaps that it was not dug into the underlying bedrock.
Part of it may appear in the Hertfordshire Historic Environment Record as monument number 17018. The record states: ‘A linear cropmark with a central dark toned area; logically a ditch, with lighter-toned banks on either side. It is likely to be archaeological rather than natural, perhaps a ditched track or a boundary.’ The evidence cited is a vertical aerial photograph dated 2010. It makes little sense as a track, as its runs against the grain of the landscape.
Something as long as this ditch is best described as a boundary. The aerial photographs suggest that it was little more than 2 m wide at the top, so we are not looking at something the size of Offa’s Dyke. Instead, we are probably looking at a more localised boundary, albeit on a considerable scale and part of a landscape rather than a single settlement or farmstead.
The earliest such boundaries in Britain date from the early Neolithic: the oldest dated example is on the west side of Hambledon Hill in Dorset, where radiocarbon determinations suggest that it was built about 3600 BC. Here, the ditch ran along the crest of the hill for almost 3 km, nearly as long as that in North Hertfordshire. However, excavation showed that at Hambledon Hill, the ditch runs in short segments, like the causewayed enclosure associated with it. Our local example appears to have been dug as a continuous feature.
Long boundary ditches became more widespread from the Middle Bronze Age on, after about 1500 BC. This was a time of population growth and increasing clearance of the land for agriculture, and such features are sometimes called ‘ranch boundaries’. At the same time, the development of bronze weapons since before 2000 BC had fuelled the rise of a warrior élite, the people whose families were often buried in the round barrows that dot the landscape. As the Bronze Age went on, so these families began to compete (in other words, fight) with each other for control of the land, and some of the linear boundaries built at this time may be early territorial markers.
On the opposite side of the valley from the eastern end of the ditch is Whiteley Hill, the site of a Late Bronze Age defended settlement. Jack Wilkerson and Mary Cra’ster excavated several trenches across its concentric ditches in 1957. We have met the pair on a previous #ArchaeologyTuesday, where we learnt about their work at Aldwick in Barley. At Whiteley Hill, they also excavated a pit located between the two settlement ditches and found most of two smashed storage jars. Although they dated the material to the Early Iron Age (about 850-400 BC), a reassessment of their work by Steward Bryant in the 1980s showed that the pottery is a Late Bronze Age type.
The entrance to Whiteley Hill is on the north side, facing away from the linear boundary ditch. This may be an indication that the focus of the settlement and its farmland lay more toward Burloes than in the valley to the south that the ditch follows. Trial trenching south of Reed Hall in the 2010s uncovered traces of Late Bronze Age settlement, but this is a site overlooking a valley further south, in the drainage basin of the River Quin, a tributary of the Lea. Perhaps we should be looking for Bronze Age activity on the top of the ridge west of Therfield. This is an area where several ring ditches show where earlier Bronze Age burial mounds once stood: Whiteley Hill sits among a group of three. There are also cropmarks of a cluster of ditches that look very like a settlement just below the crest on the north side of the ridge, northwest of Wimsey Hall Plantation. Could this be a farm in the land the boundary marks off?
Might we be looking at a boundary ditch later than the Bronze Age? This seems less likely for several reasons. During the Middle and Late Iron Ages, boundaries often took the form of multiple diches (like the Mile Ditches in the north end of Therfield parish, extending north into Cambridgeshire) or pit alignments (like one that runs for more than 4 km across the north of Iron Age Baldock). The way this one curves across the landscape is more typical of Bronze Age types, and its scale is too small for one of the early medieval dykes that are characteristic of south Cambridgeshire and elsewhere. The way it ignores the Roman road Ermine Street (now the A10) is also an indication that it is likely to be older.
One interesting feature of this long ditch is that its shape mirrors that of the ditch at Therfield Heath. Both have an eastern part trending about 25° south of east (a bearing of about 115°) and a roughly west-east northern section; as the western part of the long boundary has not (yet) been traced, we cannot say if this followed the same approximate bearing as the smaller. On the other hand, the westernmost part of the boundary ditch is pointing towards Thrift Hill, and it may be that this was its intended destination. Thrift Hill – which deserved to be the subject of another post – was a focus of enigmatic activity for millennia, from the Neolithic until recent centuries. As a focal point in the scarp of the hills, this would hardly be surprising.
The question is: why do the two ditches mirror each other but at different scales? Neither is forced to follow its course by the topography; indeed, they seem almost to work against it in places. Do they perhaps define a territory between them, focused on the dry valley? Here, the difficulty is that the long boundary ditch lies towards the foot of the slope on its southern side, while the shorter lies some distance beyond the crest on its northern side. It is probably best to conclude that their similar alignments are nothing more than coincidence and that while the long one is a territorial boundary, the shorter is more likely related to the barrows on Therfield Heath.
We are thus left with a lot of unanswered questions. This is not unusual in archaeology and can drive further research in the hope of finding some answers or, at least, pointers in the right direction. The recognition of this long boundary was unexpected, so we are at the start of a journey of exploration.

Roman food has a reputation for its exotic – and sometime, frankly repulsive – dishes. The clichéd recipes, such as dormice in honey (glires melle ac papauere sparsos) or larks’ tongues in aspic (linguas alardum in aspide, also an album by King Crimson), are found satirical literature. The wealthy did eat dormice – Apicius’s well-known de Re Coquinaria (‘On Cookery’) includes a recipe for glires stuffed with a pork forcemeat – but the idea of eating larks’ tongues originates in Monty Python’s Life of Brian. According to Pliny (Historia Naturalis X.68), phoenicopteri linguam praecipui saporis esse Apicius docuit (‘Apicius taught that the tongue of the flamingo is of supreme flavour’), although Apicius did not include a recipe for the delicacy in his book.
Of course, such pretentious foodstuffs were not everyday fare for people living throughout the Roman world. At a time when refrigeration was many centuries in the future, exotic meats and vegetables would need to be preserved – by salting or pickling, for instance – before transport. Even flamingos’ tongues would probably lose their ‘supreme flavour’ during the journey from the Mediterranean to Britain.
Bread, made from wheat or barley flour, was a staple and had been for centuries before the Roman conquest. These same grains went into making the main drinks, ceruisa, a type of low-alcohol wheat beer, and curmi, a low-alcohol barley beer. Both types were sometimes sweetened with honey or flavoured with herbs such as henbane, a poisonous plant with psychoactive effects that can, however, cause convulsions and even death. Oats were used to make porridge or gruel.
Everyday vegetables included onions, wild garlic, turnips, parsnips, cabbage, seaweed, nettles, fennel, sorrel, parsley, spinach, beans and mushrooms. Most fruit was wild, such as blackberries, gooseberries and bilberries. We have previously seen how the local people, the Succii, took their name from the pigs that they bred for meat. They also reared cattle, sheep and goats, while chickens arrived from the Roman world long before Julius Caesar had been born. People seem not to have eaten much in the way of seafood or game before the Roman conquest in AD 43. Secondary products from domesticated animals included milk, cheese and sausages.
The ability to drink milk in adulthood and eat cheese is something that many humans lack; although born with it, most people lose it after breastfeeding ends in infancy and their bodies stop making lactase, the enzyme that allows them to process the sugar lactose, found only in milk. We refer to this as lactose intolerance, but it is really lactose tolerance that is the oddity. More than 85% of north Europeans (but not Icelandic people) are lactose tolerant, but the picture is very different across the rest of the world. In Africa, south and east Asia and among Native Americans (both in North and South America), fewer than 25% of people are lactose tolerant in adulthood. In northern Europe, prehistoric populations had been drinking milk since the arrival of agriculture about 6000 years ago. They developed a genetic mutation about 4000 years ago, which spread rapidly through the population. One suggestion is that during times of disease or famine, those without lactose tolerance would die as a reaction to the milk they were drinking; those with it would benefit from digesting the lactose in the milk.
In the century between Julius Caesar and Claudius, when Britons in the southeast of the island began to adopt Roman ways, they started importing new foodstuffs. They included vegetables such as peas, cucumbers, carrots and celery. Domesticated fruits included figs, apples, pears, cherries, plums, and dates. Newly planted vineyards, like one at Barkway, meant that local wines became available. People used new flavourings such as the herbs coriander, thyme, mint, basil, bay and dill, and the famous but pungent garum (a fish sauce like southeast Asian nam pla). Exotic imported items such as ginger, laser (galangal), pepper and olives added new flavours. People also began to develop a taste for seafood, and oyster shells are a common find on Roman sites, even in places a long way from the sea. Hunting game was a new pastime for the wealthy, so we begin to see venison appearing on the menu, at least for the better off.
Iron Age cheeses may have been almost as varied as modern types. Analysis of coprolites (human stools) shows that there was a type of blue cheese, while other evidence points to making cream cheese and hard cheeses. The pot seen here, dating from the last quarter of the first century AD, was first thought to be a strainer (and, indeed, was once labelled as such in a display at Letchworth Museum). However, it is a cheese press, used for draining the whey from the curds and compressing them to make a hard cheese.
The simplest way to make cheese is to heat milk and then add something to make it curdle. This could be sour cream, beer or vinegar. Next, the curds and whey need to be separated, by allowing the whey to drain away (and be stored for other uses in cooking). This can be done in a cloth bag, which makes a soft cheese. To make a hard cheese, it is necessary to press the curd to force out any remaining whey by putting it into jar, still wrapped in its cloth, and putting weights on top. This is how the pot we see here was used.
So, someone was making a hard cheese, but on what sort of site? We know from the Letchworth Museum Accessions Register that the vessel (described as a ‘Bowl Colander’) was ‘found with shards at 2 Chimneys Sandpit March 25th 1942. 4’6” deep’. The register contains two more relevant entries: on 18 August 1952, some pottery was accessioned ‘from Two Chimneys Gravel Pit’, having been found in that year and in 1939, while one from 19 November 1953 records pottery ‘found by F J Berry’.
Historic maps show a sand pit 175 m south of The Two Chimneys public house, which was still shown on a map surveyed in 1951. This must be the place, which is now covered by Wilbury Hills Cemetery. This is just inside Stotfold parish in Bedfordshire, although the pub became part of Letchworth in the 1960s. The Bedfordshire Historic Environment Record lists the site (number 508) and suggests that it may be a disturbed burial. This is unlikely, as Percival Westell’s note on the original discovery stated that ‘[t]he occupation area is approximately 250 ft’, suggesting that the area in which the pottery was found covered more than 75 m across, too large to be a single disturbed burial. Cheese presses are functional, everyday items that are unlikely to be put into a grave as a gift for the departed, as are the quern fragments that were also found there.
Westell’s original guess that it was an occupation site is likely to be correct. Although Bedfordshire County Council commissioned an evaluation of the site, which included geophysics and trial trenching, no further Late Iron Age or Romano-British finds were made. Presumably, everything on the cemetery site lay within the outline of the sand pit and, if the occupation area was larger, it extended east across Stotfold Road. Unfortunately, no aerial photographs show activity on this side, either.
The site fits into a pattern seen across Letchworth Garden City, where almost every hilltop has produced evidence for a Roman period farmstead or village. Examples include Caslon Way on the Grange Estate, the centre of Norton village, Spring Road, Sollershott West/High Avenue and the northern edge of the Jackmans Estate. As we saw last week, individual ‘sites’ are simply part of a wider landscape, and we are lucky to have a lot of evidence locally for land use in the first century AD. We also know a great deal about Romano-British foodways (a useful American term covering the production, preparation and consumption of food), thanks less to the survival of recipes for things eaten by the wealthy and more to archaeological evidence, including data from animal bones and plant remains, things often overlooked by those who can only see glittery metalwork.
