About

St Martins ward lies in the southern part of the Caerphilly town area, characterised by residential streets and local community amenities. The housing is primarily a mix of traditional terraced homes and post-war estates, serving as a settled residential district. The ward is bordered by the main A469 road, which connects it to the wider county borough, and includes areas like the St Martins Park neighbourhood.

A notable local feature is the presence of the Twyn, a large, distinctive grassy hill that rises prominently within the ward, often used for walking and offering views. The area is functional, with several schools, a community centre, and small retail parades catering to daily needs. The landscape includes pockets of green space alongside the more urban residential layout.
