Photographic recording of the interior of the buried walls and foundations of the central tower, and the well shaft within the shell keep, by A Norris and D Graham of SyAS. The structure of the tower no longer survives above ground, with the motte having apparently been raised around the lower storeys of the tower, preserving them for examination. The tower was re-used as a well shaft in the later periods, which has been covered with an unprepossessing concrete slab for some years. The removal of the slab afforded an opportunity for a survey of the interior, which recorded four distinct levels within the shaft, with the quality of the masonry workmanship declining towards the lower levels. No evidence for windows or doors in the buried levels of the tower was observed, indicating that the intention to bury the structure had been a deliberate facet of its original construction.
