International Listings, which calls itself “the premier listing service for luxury homes worldwide”, published an article the “Top 25 Most Beautiful Castles in the World“. The list does contain some stunningly beautiful castles from around the globe like Windsor Castle which is pictured, old crusader castles, etc. Sadly, despite this being a real estate site, it does not like most of these will be on the market any time soon… but maybe if you made the queen an offer.
