List of prehistoric scheduled monuments in Powys (Brecknockshire)
# List of prehistoric scheduled monuments in Powys (Brecknockshire)

Powys is the largest administrative county in Wales. With over a quarter of Wales's land area, and 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 many prehistoric sites in Brecknockshire (also historically known as Breconshire, and not including those parts that are no longer in Powys). Brecknockshire is the southern third of Powys, and encompasses the Brecon Beacons National Park, the Black Mountains and Mynydd Epynt. The River Wye separates it from Radnorshire, and Montgomeryshire forms the northern third of Powys. There are 254 prehistoric scheduled monuments in the Brecknockshire area. Of these, 12 are neolithic burial sites. An extraordinary 190 are likely to date from the Bronze Age, mainly burial sites of various sorts but also including 44 standing stones, stones circles and stone alignments. There are 52 Iron Age hillforts, defensive and other enclosures including settlements and hut sites.

The lists of Scheduled Monuments in Powys are as follows:-

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.
