Adamsdown (Welsh: usually Adamsdown, sometimes Waunadda or Y Sblot Uchaf) is an inner city area and community in the south of Cardiff, the capital city of Wales. Adamsdown is generally located between Newport Road, to the north and the mainline railway to the south. The area includes Cardiff Prison, Cardiff Magistrates' Court, Cardiff Royal Infirmary, a University of South Wales campus, and many streets of residential housing.
In mediaeval times, Adamsdown lay just outside the east walls of Cardiff and was owned by the lords of Glamorgan. The area may be named after an Adam Kygnot, a porter at Cardiff Castle around 1330 AD. The Welsh name Waunadda derives from (g)waun (a heath or down) and the personal name Adda (Adam). This name appears to be a recent creation, and there is no evidence that Adam Kygnot was ever called 'Adda'. Y Sblot Uchaf is the Welsh name of Upper Splott, a farm that stood on the site of the later Great Eastern Hotel (demolished 2009) on the corner of Sun Street and Metal Street.
