Powys (/ˈpoʊ.ɪs/ or /ˈpaʊ.ɪs/; Welsh: [ˈpowɪs]) is a principal area, local-government county and preserved county in Mid Wales. It is named after the successor Kingdom of Powys, which formed after the Romans withdrew from Britain.
The county is named after the ancient Welsh/British Kingdom of Powys, which in the sixth century AD included the northern two thirds of the area as well as most of Shropshire and adjacent areas now in England, and came to an end when it was occupied by Llywelyn ap Gruffudd of Gwynedd during the 1260s.
The uplands retain evidence of occupation from long before the Kingdom of Powys, and before the Romans, who built roads and forts across the area. There are 1130 identified burial mounds within the county, of varying styles and ages, dating from 4000BC to 1000BC, most of them belonging to the Bronze Age. Of these, 339 are Scheduled Monuments. Standing stones, most again dating to the Bronze Age, also occur in large numbers, 276 being found across the county, of which 92 are scheduled. From the Iron Age, the county has 90 scheduled Hill forts and a further 54 enclosures and settlement sites.
