It's a home the Queen could live in if she chooses, but Fort Belvedere, located in Windsor, never seemed to make the cut. Queen Elizabeth, 95, has a home on her Windsor Estate in Berkshire that she's never lived in, despite its historical links. Fort Belvedere has often been referred to as 'The Fort' and it was hugely expanded by King George IV, who added a flag pole, annex and dining room.
