No features or deposits of archaeological interest were observed, and no artefactual material predating the modern period was recovered. 3 Portland Castle, Castletown, Dorset: Programme of Archaeological Recording © Cotswold Archaeology 1. INTRODUCTION 1.1 In March 2005 Cotswold Archaeology (CA) carried out a programme of archaeological recording on behalf of English Heritage at Portland Castle, Castletown, Dorset (centred on NGR: SY 6846 7435; Fig. 1). 1.2 The programme of archaeological recording was undertaken during the installation of new and replacement signage to fulfil a condition attached to a Certificate of Class VI Consent for Works to Properties in Care. Its objective was to record all archaeological remains exposed during the groundworks carried out. 1.3 The archaeological fieldwork followed the Standard and Guidance for an Archaeological Watching Brief issued by the Institute of Field Archaeologists (1999). The site 1.4 The monument includes an artillery castle situated along the northern shore of the Isle of Portland. It represents one of a pair of inter-visible costal fortifications constructed during the reign of Henry VIII to provide protection for Portland Harbour to the east and the sheltered waters of Weymouth Bay to the north. The castle, which dates to the mid 16th century, is a Scheduled Ancient Monument (SAM 22964) and is Listed Grade I. It includes a central fan-shaped citadel with a single storey gun room facing across the harbour, and a two storey building situated to the rear. 1.5 To the south and east of the citadel was an outer yard, bounded by a stone wall and an external ditch. The yard contained a large gun platform to the east of the citadel and a smaller example to the west. In the south-west corner of the yard was an ‘L’- shaped, two storey 17th century building incorporated into the outer wall comprising a brewhouse, stable and the sutler’s house. Methodology 1.6 Written, graphic and photographic records were compiled in accordance with the CA Technical Manual 1: Excavation Recording Manual (1996). The site archive will be deposited with English Heritage. 4 Portland Castle, Castletown, Dorset: Programme of Archaeological Recording © Cotswold Archaeology 1.7 Two postholes were hand-excavated for the installation of a replacement sign situated in a flower bed, in the location shown on Figure 2. Each posthole typically measured approximately 0.3m in diameter and was excavated to a total depth of 0.5m below present ground level. 2. RESULTS 2.1 This section provides an overview of the results of the programme of archaeological recording; detailed summaries of the recorded contexts are shown in Appendix 1. 2.2 Due to the shallow nature of the excavated postholes the underlying natural substrate was not encountered. Modern make-up/levelling material 101 containing occasional building rubble was revealed at the base of each of the postholes, overlain by garden soil 100. 2.3 Observations made by the attendant archaeologist during the excavation of the postholes identified no features or deposits of archaeological interest and, despite visual scanning of spoil, no artefactual material predating the modern period was recovered. 3. DISCUSSION AND CONCLUSION 3.1 Despite the archaeological potential of the application area the archaeological programme of recording identified no archaeological remains within the area of investigation. 4. CA PROJECT TEAM Fieldwork was undertaken by Franco Vartuca who also compiled this report. The illustrations were prepared by Lorna Gray. The archive has been compiled by Franco Vartuca and prepared for deposition by Sam Inder. The project was managed for CA by Clifford Bateman. 5 Portland Castle, Castletown, Dorset: Programme of Archaeological Recording © Cotswold Archaeology 5.
