Introduction
This collection comprises site data (digital photographs, GIS files, 3D models, videos, reports, scanned trench and context sheets, registers and drawings) from a trial trench evaluation carried out by INFRA Archaeology at Grim's Ditch, Buckinghamshire from March to July 2023.
The project forms part of Phase One of the High Speed 2 (HS2) rail project, which will involve the construction of a new railway approximately 230km (143 miles) in length between London and the West Midlands. Powers for the construction, operation and maintenance of Phase One are conferred by the High-Speed Rail (London - West Midlands) Act 2017.
Project Summary
The aims of the trial trenching were to:
- Provide a record of the Site prior to any impact from the HS2 scheme
- Confirm the presence/absence, extent and depth of any surviving archaeological remains within the Site
- Determine the nature, date, condition, state of preservation including any preservation bias, complexity and significance of any archaeological remains
- Determine the likely range, quality and quantity of artefactual and environmental evidence present
- Suggest measures, if appropriate and feasible, for further archaeological investigation to mitigate identified significant impacts, and
- Contribute to the delivery of GWSI: HERDS Specific Objectives
The trial trenching was required to help clarify the location, extent, survival and significance of any heritage assets in the vicinity of the Site and will contribute to the following specific GWSI: Historic Environment Research and Delivery Strategy (HERDS) objectives, as detailed in the Project Plan:
- KC13: What was the date of the establishment of Grim’s Ditch? What impact did it have on the landscape following its construction?
- KC15: Can we identify regional patterns in the form and location of Late Bronze Age and Iron Age settlements across the route, and are there associated differences in landscape organisation and enclosure?
- KC16: Investigate the degree of continuity that existed between Late Bronze Age and Iron Age communities in terms of population, mobility and subsistence strategies.
