Old St Mellons is a small, historic village and parish on the eastern outskirts of Cardiff in Wales, with medieval origins and a strong village feel preserved by a conservation area. The focal point is the parish church, named for Saint Mellonius, and a cluster of older cottages and a village green that contrast with the more modern suburbs known simply as St Mellons to the south.
Geographically it sits close to the main east–west routes and the M4, and economically benefits from proximity to business and retail parks such as Cardiff Gate, while retaining local shops, pubs and community groups. Socially the area blends long‑standing village families with commuters and newer residents, so it feels like a quiet, semi-rural pocket that’s still well connected to the city.
