Recently, Past to Present Archaeology began a new research project to study the Bronze Age communities of Western Suffolk. Last summer, volunteers started the archaeological investigations near Bury St Edmunds. Rupert Birtwistle, our guest writer for this week and the project’s Director, tells us all about it.
During the summer of 2021, volunteers took part in crowdfunded archaeological excavations near Bury St Edmunds to help uncover part of West Suffolk’s Prehistoric past.
The project began with a geophysical survey using a Bartington Fluxgate Dual Gradiometer. The results showed a series of large ring shapes that had the potential of being either Bronze Age burial monuments (called barrows) or a form of enclosure, or even round houses. It also revealed some linear features, probably ditches, in the north of the field.
Using the geophysics results, targeted excavation was planned to investigate the potential archaeology, with the local community. During the summer, staff and volunteers excavated four trial trenches; three of the trenches focused on the potential ring ditches, and the final trench focused on one of the linear features.
A machine excavator ‘pulled’ the trenches ready for volunteers to begin excavating. Once given a site tour, the volunteers began excavating using spades, shovels, mattocks, and trowels. To maximise the recovery of artefacts, each bucketful of spoil was sieved for finds. Each feature was also bulk sampled to undergo floatation, to recover any evidence of the past local environment.
To aid in dating the features, OSL (Optically-Simulated Luminescence) samples were also taken from the base of the features. This method of sampling gives a date on a deposit by analysing the last time quartz sediments within a deposit was exposed to light.
Once the features were excavated, they were fully recorded. This included taking photographs, undertaking technical plan and section drawings, and completing context sheets.
Many artefacts were uncovered, including an array of Bronze Age worked flints, and earlier flint implements suggesting Neolithic and Mesolithic activity in this general area. The excavations revealed evidence of ring-ditches, pits and postholes, confirming Bronze Age activity possibly relating to both settlement and burial activity. The floatation and OSL samples are currently undergoing processing, with the results following shortly.
Following the success of last summer’s work, full open excavation is due to take place summer 2022 and applications for volunteers to attend this field school are open.
