[Runequest] Spirited search for RPG castles

> 1. How many spirits can you fit in one body? (lev at rpgreview.net)

Cute.  I enjoyed reading that.  :-)

   But I have a question on another topic, if I may.
   Rummaging through my gaming closet, I found a very old RPG adventure
(from Basic D&D) with a castle & some details about it.  For example,
how many guards there are in each tower, what it takes to get in good
with the castellan, etc.  And, of course, floor plans.
   What RQ products are there with adventures set in or around castles?
   Or, failing that, any other RPG source for castles-ready-to-play one
might recommend?
   Any guidance is warmly welcome.
   Sincerely,
Asher
