Abstract: |
An archaeological watching brief was carried out during the excavation of boreholes and trial pits at 117-121 Bishopsgate. The work was conducted in advance of proposed redevelopment of the site, in external pavement and parking areas and within an internal basement. Excavation of the trial pits was of limited value as only modern materials and natural Terrace Gravels were revealed. The borehole excavations were far more informative with the earliest material recorded being London Clay. This was sealed by extensive Pleistocene Terrace Gravel deposits, which were capped by brickearth up to 1.8m thick towards the south of the site but truncated towards the north and west, probably by quarrying. The earliest finds recovered were fragments of Roman tile, but this material appears to have been residual within later deposits. The earliest activity on the site was probably during the medieval period and most likely involved brickearth quarrying, quarry backfill deposits being tentatively identified in two of the sequences and truncation of brickearth most extensively apparent towards the east of the site. Activity continued into the early post-medieval period as evidenced by a possible wall footing recorded at the south of the site and most likely associated with early development along the north side of Alderman's Walk. There was probably also ground raising at this time. Nineteenth-century activity on the site was represented by apparent rebuilding and re-use of the wall footing and further ground-raising. Rubble deposits probably associated with 20th-century demolition and redevelopment of the site were observed in all cores and each sequence was capped by modern surface materials associated with the most recent site development. |
