# List of prehistoric scheduled monuments in Powys (Radnorshire)

Powys is the largest administrative county in Wales. With over a quarter of Wales's land area, covering much of the eastern half of the country, it is a county of remote uplands, low population and no coastline. It was created in more or less its current form in 1974, and is the only one of the large county units created at that time to have been carried forward intact at the 1996 local government re-organisation. It comprises three historic counties, namely Montgomeryshire, Radnorshire, and most of Brecknockshire. There are 950 scheduled monuments within the county, which is far more than can be sensibly covered in one list. Each of the 3 historic counties is therefore listed separately, and each of these has two lists - one for the prehistoric sites and one for the Roman, medieval and post-medieval sites.
This list shows the prehistoric sites in Radnorshire, which occupies the central third of Powys. The River Wye separates it from Brecknockshire to the south, and Montgomeryshire forms the northern third of Powys. There are 139 prehistoric scheduled monuments in the Radnorshire area. Of these, only two are Neolithic burial sites whilst 117 are likely to date from the Bronze Age, mainly burial sites of various sorts but also including a cup-marked stone, 11 stone circles and stone alignments, and 17 standing stones. There are 20 Iron Age hillforts, defensive and other enclosures.
The lists of Scheduled Monuments in Powys are as follows:-
* List of Scheduled prehistoric Monuments in Powys (Brecknockshire) (254 sites)
* List of Scheduled Roman to modern Monuments in Powys (Brecknockshire) (135 sites)
* List of Scheduled prehistoric Monuments in Powys (Radnorshire) (139 sites - shown below)
* List of Scheduled Roman to modern Monuments in Powys (Radnorshire) (119 sites)
* List of Scheduled prehistoric Monuments in Powys (Montgomeryshire) (190 sites)
* List of Scheduled Roman to modern Monuments in Powys (Montgomeryshire) (113 sites)
Scheduled Ancient Monuments (SAMs) have statutory protection. It is illegal to disturb the ground surface or any standing remains. The compilation of the list is undertaken by Cadw Welsh Historic Monuments, which is an executive agency of the National Assembly of Wales. The list of scheduled monuments below is supplied by Cadw with additional material from RCAHMW and Clwyd-Powys Archaeological Trust.
