Angers was the home of the Counts of Anjou, who had the name "plante à genta" which after the then Count had also become King of England became Plantagenet.  The list of titles held by the count at that time included Duke of Normandy and Duke of Aquitaine.  The history of this is long and complicated so I won't attempt to cover it here, suffice it to say that this situation was at the root of the Hundred Years War.

  On this page are three photos of the château in Angers, noted for its black and white towers and the deer in the dry moat.

  The last photo is of small square near to the Château, there's history in Angers but it is also a bustling modern city.
