Andy, thank you very much! )  What are the locations of those lost buildings?  All in Aachen?  I was wondering if the Holy Roman Empire was supposed to be inclusive for the whole of Western Europe, such as unofficially having traditionally independent places as England and other Catholic lands as subdivisions during that time.  The reason being, that there was only one emperor during those times(in the West) and only after Protestantism did multiple emperors become a feature of Western Europe.  Was the King of England a Sovereign during the time predating the Anglican schism, or was he subordinate to the Holy Roman Emperor?  I postulate this, due to the fact that the Cardinals and Archbishops were subordinate to the Pope and figured that there's some part of history not being told to enough children.  Wouldn't that be a reason to break with the Vatican back then?  Once Henry broke with the Church, he was able to incorporate Wales and the Royal House changed from province to surname.  I was thinking that the provincial royal house like Anjou, Blois or Normandy is a Continental style.  Once England broke away, they went to personal names like Tudor and Stuart...even though Henry was technically of the House of Richmond.  Once England had become the center of another empire, just of its own, they reverted to usage of provincial houses.  So, what do you think...Am I right?
