Ceredigion (Welsh pronunciation: [kɛrɛˈdɪɡjɔn] ) is a county in Mid Wales. In the Middle Ages, it was a minor kingdom also known for a time as Seisyllwg. Following its Norman conquest, the name was anglicised to Cardigan and then Cardiganshire (Welsh: Sir Aberteifi) and it began to be administered as a county in 1282. This historic county was abolished in 1974 before being reconstituted in 1996 under the Welsh name Ceredigion. The county had a population of 75,900 at the 2011 UK census. Its largest town, Aberystwyth, is one of the two administrative centres; the other being Aberaeron. Aberystwyth houses Aberystwyth University, Bronglais Hospital and the National Library of Wales. The inland town of Lampeter houses part of the University of Wales Trinity Saint David.
