The Mid Glamorgan County Main Emergency Centre was one of the last purpose built protected emergency centres opening in 1993 under the Magistrates Court in Llwynypia (entrance at the rear). It acted as joint emergency centre with Rhondda District Council and is still in use as the Rhondda Cynon Taff Joint Emergency Centre.
It replaced the bunker at Waterton (Bridgend), an ex-Civil Defence Corps bunker that was refurbished in 1981 but abandoned after local protests - the site has now been cleared.
