I've had this one sitting around for awhile so I decided to upload it.

It's my first attempt at a round tower but i wanted to make it look like it was coming out the mountain side, plus I only have a small amount a Lego so I restrict the size of the base hence why its a half round tower
I'm not really happy with how the top woodwork came out, but I might find a better solution another time.
