The Norman town of Bayeux has their own famed basilica and cathedral (the second largest of its kind in France, behind the one on the Paris) and it's well worth the trip while you're in town seeing the Bayeux Tapestry or waiting for your pick-up with the D-Day visit that you may have planned.
This Norman-Romanesque church was the original home of the Bayeux Tapestry and has been recognized as an official, national monument of France.
The cathedral that you see today was consecrated on 14 July 1077 in the presence of William, Duke of Normandy and King of England. If you know your history, you'll know that It was here that William forced Harold Godwinson to take the oath- that the betrayal of- would lead to the Norman conquest of England.
