Aberystwyth (informally: Aber, not to be confused with many other coastal towns in Wales) is in the county of Ceredigion, in Wales.
Aberystwyth, called the true capital of Wales by some, is a smallish town on the Ceredigion coast, just below the Dyfi estuary. Politically, it's in the heart of Nationalist Wales, and is the birthplace of Cymdeithas Yr Iaith Gymraeg, the Welsh Language movement. It is home to one of the oldest parts of the University of Wales, which is attended by some 9,000 students. It is also home to the National Library of Wales, one of the UK's few copyright libraries, meaning it has the right to claim a copy of every book published in Britain, which also means that it has one of the highest figures for books per head of population in the world. Its other notable - and notorious - feature is the remarkable number of pubs in the town.
