SOUTH GLAMORGAN
Additions : 1974 Glamorgan (partly)
Origin/meaning :
South Glamorgan was created in 1974 when Glamorgan was broken into three.
The county consisted of two districts - the City of Cardiff, and the Vale of Glamorgan. This is reflected in the arms. The roundel is for Cardiff. It shows the red chevronels on gold of De Clare and the silver chevronels on red of Iestyn ab Gwrgant, last Welsh ruler of Morgannwg. The roundel is crowned to show that Cardiff is the capital city of Wales. The green and ermine field shows the rich Vale of Glamorgan, guarde by its castles.
The crest has the mural crown of local government, from which rises a golden mitre for the See of Llandaff.
The dexter supporter is the red dragon of Wales. He is balanced on the sinister side by a red lion from the arms of the Princes of South Wales. The lion's wings are for the airfields at Rhoose and St. Athans. Both supporters hold a golden trident, to show that the county contains important seaports at Cardiff and Barry.
The motto - Y DDINAS A'R FRO - means the City and the Vale.
