It's in my blood to make Castles.
I tend to never finish them though.
http://www.worth1000.com/entries/619730/castle-von-morderThis is the only Castle which I even remotely finished, back in Minecraft Classic. And even then, CASTLING NEVER FINISHES. IT'S NEVER COMPLETE AUUUGH
here's one I'm currently working on,
I'm making it in survival, so obviously it isn't as easy. Haven't worked on it in a while. prolly should.
And another I made on a friend's server. The server's down, and this is the only screenshot I have of it for a reason which escapes me right now. Again, I never finished it. Though it was in this case more of a topographic issue. I always search for high mountainous land for castles. i found the best spot for this place, but the server's land was all jacked up, like, for example, where the Castle was, there was the hillside, and then a flat drop to a beach because the land generation was messed up. I couldn't figure out what to do with the layout of the castle either, so I kind of got bored with it and gave up.
I made a neat Clocktower on that server too, (different map though) I should probably ask my friend to put the server back up one of these days and post pics of it.
