Osborne House on the isle of wight was the stately marine residence where Queen Victoria spent so many quiet days, and where on January 22, 1901 she passed away. It's not a castle though. She lived in Windsor Castle and Balmoral.
Matron 22, Really in a strop now LOL!! In the middle of my dinner, it struck me that I had actually been to the Northern bird sanctuary at Muncaster Castle in the Lake District so logged back on to give you the answer! Go and sit on the naughty step immediately!!!!
Kustard, I am so sorry to have ruined your dinner. Must have been having a senior moment. Long time since someone told me to sit in the naughty step !!!!!!
