About

St Mellons West is a residential district situated in the east of Cardiff, bordering the River Rhymney. The area is characterised by a mix of housing, primarily from the late 20th century, with a significant number of semi-detached and terraced homes. Its layout includes several local shopping parades providing everyday amenities, alongside community facilities like schools and a library serving the neighbourhood's needs.

The area is defined by its proximity to large areas of open green space, including the expansive Rumney Recreation Ground to the north. A notable local feature is the historic St Mellons Church, which stands separate from the modern housing estates, marking the older settlement core. Road connections via the A48 are central to the area, linking it to Cardiff city centre and Newport.
