About

The Town area of Merthyr Tydfil sits where the A470 corridor meets the upper Taff valley. The river runs through the centre and the Merthyr Line railway station provides regular services to Cardiff, linking the town with the Valleys and the capital. Main streets around the market and civic buildings concentrate shops, council services and the bus interchange used for local and regional routes. Streets rise quickly from the centre, reflecting the town’s position on the valley side and the pattern of terraces and short cul-de-sacs created during 19th and 20th century development.

Gelli-deg lies just off the town centre and is primarily residential, with rows of mid-century housing and a cluster of local shops and community facilities. A youth centre and a primary school serve the neighbourhood; the school’s playing field sits within walking distance of the housing. Paths from Gelli-deg link to riverside routes that follow the Taff, used by commuters and walkers moving between the estate and the town. Street layouts and local lanes make the area compact, and day-to-day life is centred on those community points and the transport links into the town.
