The county is named after the ancient Welsh
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 4000 BC to 1000 BC, 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
hillforts and a further 54 enclosures and settlement sites. Powys is served by the
Cambrian Line and
Heart of Wales line which offer connections to major towns and cities such as
Swansea,
Wrexham,
Shrewsbury,
Birmingham,
Wolverhampton,
Manchester,
Cardiff,
Aberystwyth,
London and
Telford. The county used to be served by key railways such as the
Mid-Wales Railway,
Oswestry and Newtown Railway,
Tanat Valley Light Railway,
Llanfyllin Branch,
Leominster and Kington Railway,
Swansea Vale Railway and the
Hereford, Hay and Brecon Railway, all of which offered connections to
South Wales,
Hereford,
Oswestry,
North Wales and
West Wales but have all since closed. ==Heraldry==
