About

Penmaen is a residential ward located on the northern edge of the Caerphilly county borough. The area is characterised by housing estates and terraced homes situated on the hillsides overlooking the Sirhowy Valley. It falls within the community of New Tredegar, with its landscape shaped by its position on the eastern slopes of the South Wales Valleys. The ward provides local services and green spaces for its inhabitants within this distinct topographic setting.

A notable local feature is the Penmaen Viaduct, a disused railway structure that spans the valley. The area's history is connected to the coal industry, with former colliery sites now largely reclaimed by nature. Walking paths along the old railway lines and through woodland areas offer views across the valley. The ward maintains a quiet, community-focused atmosphere separate from the larger town centres in the region.
