The Cadw schedule on which this list is based makes no distinctions between different prehistoric periods. The following notes explain where period classifications have been refined, based on the (cited) records from RCAHMW and/or Glamorgan-Gwent Archaeological Trust.
- The Cadw spreadsheet lists sites by vary broad categories, for example, Prehistoric covers Paleolithic to Iron Age. Where possible, the Period has been changed, based on the (cited) records from Coflein and/or GGAT.
- The six castles are Cas Troggy, Dinham, Llanvaches, Llanvair, Pencoed, and Penhow.
- The Three Castles in the Monnow valley (Grosmont, Skenfrith and White castles) were brought together under a single lordship by King Stephen in 1138. The castles share many features of design and construction, and the existing remains all date from the 11th century, when under the control of Hubert de Burgh, with some later building. All three castles remained in common ownership until 1902,:46 and are all now in state care, under the guardianship of Cadw. The castles are linked by the Three Castles Walk.
