Could you give an example? The author of essay is in the UK, and the mentioned castles are all homes for royals, nobility, or bishops, or at least meant to be.

Could you give an example? The author of essay is in the UK, and the mentioned castles are all homes for royals, nobility, or bishops, or at least meant to be. Arundel Castle, West Sussex - that's where the Earl of Arundel has lived (https://en.wikipedia.org/wiki/Arundel_Castle https://en.wikipedia.org/wiki/Arundel_Castle) Newark Castle (Nottinghamshire) - for the Bishop of Lincoln (https://en.wikipedia.org/wiki/Newark_Castle%2C_Nottinghamshire https://en.wikipedia.org/wiki/Newark_Castle%2C_Nottinghamshi...) Norwich - "Norwich Castle was designed to be a royal palace rather than a fortification. However, no Norman kings ever lived in it" (https://www.museums.norfolk.gov.uk/norwich-castle/whats-here/history-of-norwich-castle https://www.museums.norfolk.gov.uk/norwich-castle/whats-here...) Tower of London - I can't tell if William the Conqueror lived there, but the Wikipedia entry says that by 1135 "The castle, which had not been used as a royal residence for some time", implying it was a royal residence (https://en.wikipedia.org/wiki/Tower_of_London https://en.wikipedia.org/wiki/Tower_of_London) Caerphilly - given "the castle's luxurious accommodation", I assume Gilbert de Clare lived there. https://en.wikipedia.org/wiki/Caerphilly_Castle https://en.wikipedia.org/wiki/Caerphilly_Castle Conwy - "best preserved suite of medieval private royal chambers in England and Wales" (https://en.wikipedia.org/wiki/Conwy_Castle https://en.wikipedia.org/wiki/Conwy_Castle) This is too boring, so I'll let someone else look up Beaumaris, Caernarfon, and Colchester Castle.
