Pen y Bryn

The Kingdom of Ceredigion was one of several Welsh kingdoms that emerged in post-Roman Britain in the mid-5th century. Cardigan Bay to the west and the surrounding hilly geography made it difficult for foreign invaders to conquer. Its area corresponded roughly to that of the county of Ceredigion. Ceredigion transparently means "the people of Ceredig." The kingdom as an independent entity ceased to exist around the year 872.

Powys Wenwynwyn or Powys Cyfeiliog was a Welsh kingdom which existed during the high Middle Ages. The realm was the southern portion of the former princely state of Powys which split following the death of Madog ap Maredudd of Powys in 1160: the northern portion (Maelor) went to Gruffydd Maelor and eventually became known as Powys Fadog; while the southern portion (Cyfeiliog) going to Owain Cyfeiliog and becoming known, eventually, as Powys Wenwynwyn after Prince Gwenwynwyn ab Owain, its second ruler. Powys Wenwynwyn and Gwynedd became bitter rivals in the years that followed, with the former frequently allying itself with England to further its own aims of weakening the latter.

The Kingdom of Powys (Welsh: Teyrnas Powys; Latin: Regnum Poysiae) was a Welsh successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. It very roughly covered the northern two-thirds of the modern county of Powys and part of today's English West Midlands (see map). More precisely, and based on the Romano-British tribal lands of the Ordovices in the west and the Cornovii in the east, its boundaries originally extended from the Cambrian Mountains in the west to include the modern West Midlands region of England in the east. The fertile river valleys of the Severn and Tern are found here, and this region is referred to in later Welsh literature as "the Paradise of Powys" (an epithet retained in Welsh for the modern UK county).

Seisyllwg (Welsh: [sɛiˈsəɬʊɡ]) was a petty kingdom of medieval Wales. It is unclear when it emerged as a distinct unit, but according to later sources it consisted of the former Kingdom of Ceredigion plus the region known as Ystrad Tywi. Thus it covered the modern county of Ceredigion, part of Carmarthenshire, and the Gower Peninsula. It is evidently named after Seisyll, king of Ceredigion in the 7th or early 8th century, but it is unknown if he was directly responsible for its establishment. In the 10th century Seisyllwg became the centre of power for Hywel Dda, who came to rule most of Wales. In 920 Hywel merged Seisyllwg with the Kingdom of Dyfed to form the new kingdom of Deheubarth.

Glywysing was, from the sub-Roman period to the Early Middle Ages, a petty kingdom in south-east Wales. Its people were descended from the Iron Age tribe of the Silures, and frequently in union with Gwent, merging to form Morgannwg.

Abergwyngregyn (Welsh: [abɛrɡwɨnˈɡrɛɡɨn]) is a village and community of historical note in Gwynedd, a county and principal area in Wales. Under its historic name of Aber Garth Celyn it was the seat of Llywelyn ap Gruffudd. It lies in the historic county of Caernarfonshire. It is located at grid reference SH653726, adjacent to the A55, five miles (8 km) east of Bangor, eight miles (13 km) west of Conwy.

The Anafon River, or Afon Anafon, is a river in Gwynedd, Wales, that flows into the Afon Aber. It originates on the slopes of Foel-fras and the Drum of the Carneddau. It flows into Glyn Anafon. then north-west along the Anafon Valley, flowing past monuments of the Iron Age and the Bronze Age. It joins with the Aber Estuary just above the New Bridge, the bridge over the river on the way to the back of Abergwyngregyn.

Aber railway station was a railway station on the North Wales Coast Line in the Welsh county of Gwynedd. Although trains still pass on the main line the station closed in 1960. A signal box on the site remained in use until the installation of colour light signalling.

Coedydd Aber National Nature Reserve lies tucked away in a steep valley on the northern flanks of the Carneddau mountains, roughly midway between Bangor and Llanfairfechan in Gwynedd, Wales. Water cascades over a hard shelf of volcanic rock at the far end of the Aber valley, before plummeting 100m down the Aber Falls to flow swiftly along a torrential river channel to the sea. The nearby village of Abergwyngregyn was an important centre for the Welsh princes in the 13th century, and the valley contains some remains from this period.

Aber Falls (Welsh: Rhaeadr Fawr) is a waterfall located about two miles (3 km) south of the village of Abergwyngregyn, Gwynedd, Wales. The waterfall is formed as the Afon Goch plunges about 120 feet (37 m) over a sill of igneous rock in the foothills of the Carneddau range. Two tributaries merge; the enlarged stream is known as Afon Rhaeadr Fawr; from the road bridge, Bont Newydd ("New Bridge"), the name becomes Afon Aber.
