[1] As archaeologist Phil Mcmahon describes, documentary sources imply the castle was "a rectangular stone-built structure with six towers, incorporating a hall, an inner and outer gate, a deep well and a chapel", and it may have resembled a smaller version of Framlingham Castle.

[3] The castle was probably entered from the west, with a possible road running up the south side of the hill.

[6] Edward II gave it to his royal favourite, Piers Gaveston, whom he made Earl of Cornwall.

[9] A flagpole, which is illuminated at night, and a memorial to the 43rd (Wessex) Infantry Division are located on the castle site.

[11] Archaeological excavations of the site were carried out in 1887 by T. H. Baker and C. N. Wyld, but most of the results of their work were subsequently lost.
