The next link describes an attack on a German Hign Command Headquarters in a Chateau near Bayeux.

Other sites say the low level attack included eight aircraft from 197 squadron led by Wing Commander Baker.
Here the location is described as “Chateau Le Parc” SE of Bayeux. Also attacked by other Typhoon units was a Chateau near St Lo. I think the attack near St Lo was against General Marcks HQ.

Unfortunately, I can not find any other references to a "Chateau le Parc" SE of Bayeux. I don't think the name is "correct", but maybe it will give someone a clue.
Also a mention here:
