Sounds like an interesting read. :-)
I’d love to know which book you chose.
The book is Castles of Britain and Ireland by Rodney Castleden. I got it at Barnes and Nobels last week and I have only looked at pictures and checked the dates. But I plan to read it all. I am hoping I can remember the ones that I have visited but it was in 1963, that is a long time ago. I have been to England several times since then but ‘63 is when we did all 3 countries and saw so many castles.
