This archaeological desk top assessment was requested by Bidwells Ltd on behalf of Trinity College to assess the potential for the survival or discovery of archaeological features, artefacts and building remains within Brewhouse Yard, Trinity College. Evaluation of selected archaeological, historical and cartographic evidence shows the site to be located within an area of rich historical and architectural significance, dating from the 12th Century AD to the present date, including extant listed buildings and adjacent to former Medieval back-plots, an ancient route, formal gardens and site of a stone yard. There exists a reasonable possibility of encountering artefacts and features pre-dating current buildings and surrounding extant features, with a higher probability of recovering and identifying waterlogged items.
