Dinas Powys (also spelt 'Dinas Powis') is a large village and a community in the Vale of Glamorgan in South Wales which takes its name from the Dinas Powys hillfort that dates from the Iron Age. The village is south-west of the centre of Cardiff and conveniently situated on the A4055 Cardiff to Barry main road. It is generally regarded as a pleasant dormitory village for Cardiff's commerce and industry commuters since the city has expanded with widespread development around the Cardiff Bay area.
