Actually, Buckingham is bigger in terms of royal living space, since the royals are generally "Confined" to the dungeon at Windsor. (And no, the Dungeon is not a dank, musty underground chamber, it's a huge circular moat surrounded structure.) Buckingham is in london proper. (Not The City of London, but the London Metro) Windsor is the "country castle." As such, Buckingham is a bit more constrained by urban development than Windsor. Of course there is Kinsignton Palace, and the massive gardens surrounding it, even though it is also in London Metro. IMHO, Neither Buckingham or Windsor look like castles. Buckingham is a house. A BIG house. Windsor looks more castle/palace like, but is still more House than Fairy Tale. I'm partial to some of the northern castles, such as Endinburg Castle. Now, that's a castle, perched up on a craggy cliff, the city spilling down one side of the hill. But hey, I read to many fantasy novels as a kid. Then there is always the Tower of London, which I think is more castle/palace like than Buckingham. Very cool, and not much of a Tower. Of course, then you can go play on the Tower Bridge... Rats, I thought I'd gotten all that English stuff out of the system on my last visit. (Starts looking through travel brocures)
