There are four early Christian sites from early medieval times. The 101 sites from the medieval post-Norman period include spectacular castles and hidden castle mounds, remote dwellings, grand abbeys, holy wells, stones and churches. Finally the modern period has a 39 sites, including a very wide range of early industrial activities.

Scheduled Ancient Monuments (SAMs) have statutory protection. The compilation of the list is undertaken by Cadw Welsh Historic Monuments, which is an executive agency of the National Assembly of Wales.[1] The list of scheduled monuments below is supplied by Cadw[2] with additional material from RCAHMW and Glamorgan-Gwent Archaeological Trust.

Two large roughly rectangular enclosures surrounded by ditches and the River Trothy. Constructed in 1184 but immediately raided. The shape and size are unusual for a motte and bailey in the region, and may have been the start of a masonry castle. Excavations in 1969 found no masonry remains. May have been abandoned, or built using wood pallisades, as the castle was noted in 1469.

Notes[edit]

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.

  1. ^ 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.
  2. ^ a b c The six castles are Cas Troggy, Dinham, Llanvaches, Llanvair, Pencoed, and Penhow.[73]
  3. ^ a b c 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,[72]:46 and are all now in state care, under the guardianship of Cadw. The castles are linked by the Three Castles Walk.
