The watching brief involved monitoring the excavation of two post-holes to accommodate uprights for a new display panel outside the west gate of Bremenium Roman Fort. These post-holes were excavated by hand - by a specialist signage installation contractor. The Field Investigation was carried out by means of an Archaeological Watching Brief; all work was carried out in line with the Institute for Archaeologists By-Laws - Code of Conduct (CIFA 2010) and the Yorkshire, The Humber and the North East Regional Statement of Good Practice for Archaeology in the Development Process (2009). Accordingly, all excavations were closely monitored by a suitably trained and experienced archaeologist from The Archaeological Practice Ltd. The watching brief site was located in the field-verge approximately 7 m to the west of (and exterior to) the fort's western gateway (centred upon NGR: NY 83206 98612). Bremenium was for two centuries the northernmost fort of the Roman Empire and its outline remains clearly visible, defining the boundaries of the current settlement of High Rochester, with multiple ditch & bank ramparts present on all but the west sides. The results of archaeological watching brief concluded that no significant remains of any kind were observed in the small post-holes excavated for the new display board to the depth of 0.30 m below ground level. Below the topsoil was a deposit of loamy sandstone rubble, observed to the maximum depth of excavation and extending in every direction. Although compact, this rubble had no structural form and has been interpreted as infill or clearance rubble. No further archaeological mitigation work is required in association with this scheme.
