Recorded monuments

• DU012-034 Castle - motte and bailey
  Description

  Located in level ground this is a flat-topped elongated mound (Top: L 10m; Wth 7.5m; Base: L 22m) with a flat-bottomed fosse (Wth 5.7m; D 1.25-1.5m) enclosing the north side. There are indications of an intervening berm (Wth 2m). The fosse stops abruptly in the S where the ground is uneven indicating the possible presence of a bailey (Healy 1975, 26; Flanagan 1984, 24). Geophysical survey (Licence no. 12R0028) was undertaken to define the limits of the motte and bailey. Three potential structures, possible pit-type features and burnt/fired remains were identified to the south of the motte (Nicholls 2012, 3).
