NS 0155 3786 A geophysical survey at Brodick Castle (NMRS NS03NW 2) was undertaken in June 2001. The survey aimed to locate the ditches that defended the original 13th-century castle on the site but which were filled in during the 19th century. It was also hoped that the technique used would allow a 3-dimensional model of the bedrock around the site to be constructed, and possibly locate any remains which may be associated with a 'secret tunnel' that tradition says linked the castle to the shoreline. The work was conducted using a Wenner array capable of producing resistivity profiles down through the soil. Around 24 transects of different lengths were surveyed around the castle but focused on the flat area to the NW, outside the castle courtyard, and on the garden terraces to the SE. Initial results look promising, with the line of a wide ditch possibly being located to the NW.

Report to be lodged with the NMRS.
