Cardigan, Ceredigion in the context of Tenby

In Welsh mythology, Arawn (Welsh pronunciation: [ˈarau̯n]) was the king of the otherworld realm of Annwn who appears prominently in the first branch of the Mabinogi, and alluded to in the fourth. In later tradition, the role of the king of Annwn was largely attributed to the Welsh psychopomp, Gwyn ap Nudd - meaning "white" (i.e. 'winter') a possible kenning for his true name. However, Arawn's memory is retained in a traditional saying found in an old Cardigan folktale:

The name Arawn is derived from that of the biblical prophet Aaron.

Ceredigion (Welsh: [kɛrɛˈdɪɡjɔn] ), historically Cardiganshire (/ˈkɑːrdɪɡənˌʃɪər, -ʃər/, Welsh: Sir Aberteifi), is a county in the west of Wales. It borders Gwynedd across the Dyfi estuary to the north, Powys to the east, Carmarthenshire and Pembrokeshire to the south, and the Irish Sea to the west. Aberystwyth is the largest settlement and, together with Aberaeron, is an administrative centre of Ceredigion County Council.

The county is the second most sparsely populated in Wales, with an area of 688 square miles (1,780 km) and a population of 71,500; the latter is a decline of 4,492 since the 2011 census. After Aberystwyth (15,935), the largest towns are Cardigan (4,184) and Lampeter (2,970). Ceredigion is considered a centre of Welsh culture, and as of the 2021 census, 45.3% of the population could speak the Welsh language.

The River Teifi, is a river in Wales. It forms the boundary for most of its length between the Welsh counties of Ceredigion and Carmarthenshire, and for the final 3 miles (4.8 km) of its total length of 76 miles (122 km), the boundary between Ceredigion and Pembrokeshire. Its estuary is northwest of Cardigan, known in Welsh as Aberteifi, meaning 'mouth of the Teifi'.
