Geophysical survey was to be undertaken at Broughty Castle as part of an archaeological evaluation instigated because of the occurrence of subsidence events in an area of lawns to the north-east of the castle known as Castle Green, by Broughty Ferry, Dundee… Electrical resistance was used with the objective of assessing the presence of building remains and identifying areas at future risk of subsidence. The survey objectives were deemed to have been met through the provision of the possible location of additional voids, correlating with the site of 19th century primer pits and other ancillary military buildings adjacent to the Broughty Castle ramp. Moreover the results indicated variation in the survival of building remains across the site, including areas of general clearance, possible robbed wall foundations and in situ foundations.
NO 4647 3042 A geophysical survey was undertaken on 12 December 2008 as part of an evaluation to investigate the potential causes of subsidence in an area of lawns known as the Castle Green; formerly the site of a 19th-century mariners’ military base. A resistivity area survey (0.16ha) and resistivity profiling were undertaken. The site of 19th-century primer pits and ancillary military buildings were identified, with areas of potential voiding.
