Description

A watching brief was carried out on groundworks to reconstruct the car-park on the eastern side of the school grounds. This involved removing the old tarmac surface, creating a new path and cycle storage compound, and digging trenches for lighting cables. The groundworks largely affected modern and post-medieval layers. In one lighting cable trench, however, the Roman ground-surface was exposed but no archaeological features were observed. <1> Four visits were made while contractors were stripping off the previous car-park surface and sub-base down to a depth of approximately 300mm. Turf and topsoil areas at the edge of the car-park were also stripped down to a depth of 300mm. Nothing other than modern deposits were recorded during this phase. Five visits were made during the digging of trenches for lighting cables. The trenches were approximately 400mm deep (below the reduced ground-level) and did not disturb any archaeological deposits. During this phase, the concrete slab for the cycle storage compound was constructed. Part of this area had previously housed a greenhouse and the groundworks did not extend deeper than the foundations of this structure. Two visits were made during works to create a path around the eastern and northern perimeter of the site. This involved the removal of turf and topsoil. This ground reduction did not extend deeper than the topsoil. Trenches were dug on either side of the path for lighting cables. These trenches were 600-700mm deep and were mainly dug through topsoil. Some of the deeper trenches did expose a light yellowish brown silty layer which is the Roman ground-surface. No features were exposed.
