Thornhill (Welsh Draenen Pen-y-graig draen thorn + -en one + pen top + 'y' the + craig rock [mutated to 'graig']) is a northern suburb in the city of Cardiff, capital of Wales, south of Caerphilly. It is a relatively modern area with housing stock dating mainly from the late 1980s and beyond. The area has a centralised precinct providing services, comprising a community centre (Thornhill Church Centre), a Sainsbury's supermarket, with an integral Post Office and Pharmacy; and a Medical Centre.
There are four public houses located in Thornhill: the Old Cottage, Pendragon, Pentre Gwilym House and the Ffynnon Wen. A fifth pub, The Traveller's Rest is de facto in Thornhill due to its geographic location; although it is de jure in Caerphilly based on its postcode and council locale. Despite being placed directly off the M4 corridor, Thornhill has no motorway junction; although it is generally theorised amongst residents that the long awaited 'Junction 31' will serve Thornhill.
Thornhill Cemetery is a major cemetery located in this area of Cardiff. Thornhill crematorium was built on this site during the 1950s as a dedicated crematorium. This differs from the crematorium that was set up in nearby Glyntaff; this in contrast was a chapel that was originally used for traditional burials and modified to serve as a crematorium.
Most of Thornhill's residential development took place during the 1990s, Cardiff County Council originally planned Thornhill as "The Villages of Thornhill"; with clusters of houses interspersed by large "green" areas. These green areas were short lived as rapid housing development resulted in homes being built in areas adjoining the "Villages".
Thornhill also houses a few tucked away historical sites including the remains of a castle situated close to the Caerphilly/Thornhill border known as Castell Morgraig.
Thornhill falls into the Llanishen Ward on Cardiff County Council.
- Thornhill is also served by bus services operated by Cardiff Bus. The 28 service runs through Thornhill and terminates at the Central Bus Station at regular intervals. Stagecoach Service A and B run every 30 mins from Cardiff Central Bus Station and stops outside cemetery.
- The M4 motorway passes through Thornhill between junctions 30 and 32 but there is no interchange.
The area is served by Thornhill Primary School. The nearest secondary school is Llanishen High School. Welsh medium education is provided most locally at Ysgol Y Wern in nearby Llanishen and Ysgol Gyfun Gymraeg Glantaf in Llandaf North.
