Gabalfa (English pronunciation: /ɡəˈbælvə/, Welsh pronunciation: [ɡaˈbalva]) is a district in the north of the city of Cardiff, capital of Wales. It is characterised by an enormous fly over road at the Gabalfa Interchange, where the A48 road meets the A470 road (North Road) which leads from Cardiff to northern Wales, and the A469 road (Caerphilly Road). The area is also the site of the All Nations Centre.
