Glamorganshire Golf Club is located in Lower Penarth in the Vale of Glamorgan, Wales, 7.3 miles (11.7 kilometres) south west from the capital city of Cardiff and is one of the oldest golf clubs in Wales. The club was founded by the Earl of Plymouth.
The club played a leading role in the founding of the Welsh Golf Union, and it twice hosted the Welsh Amateur Championship as well as the Welsh Ladies inaugural Championships in it early years.
In 1898 the club was the testing ground of Dr Frank Stableford's new Stableford revolutionary golf scoring system still used today.
Although near the sea, the Glamorganshire course is not a links, but an 18-hole parkland course on gently undulating ground at the eastern edge of what is now Cosmeston Lakes Country Park.
