Here is one of the most beautiful Gothic houses I could find on the internet: Shandon House, a 19th century Scottish revival manor/castle overlooking Gare Loch in Scotland. The house was built in 1849 on 31 acres of beautiful Scottish hills. It was owned by various grandees (shipping magnates, tobacco merchants, and such), before becoming a boys’ school, but the school then closed in the mid-eighties.
The region where Shandon House is located is dominated by Faslane Naval Base, one of the three ports of the Royal Navy in the United Kingdom (and arguably the most important). So Shandon House was purchased by the Ministry of Defense…but since the Ministry of Defense has no actual use for dark fairy tale castles, the house has been derelict for over a decade, and may now be beyond repair. As far as I can tell, the MOD is incapable of finding buyers and hopes to knock the house down (although its designation as a historical landmark makes such an outcome somewhat unlikely).
It is a shame the house is decaying away, since this is truly an elegant and imposing structure. On the other hand, who would actually live here other than evil sorcerers, mad scientists, Dalmatian coat enthusiasts, and other suchlike Disney villain folk?
