Keeping in mind that this was before I knew about the magic that is Hirst, I am pretty proud of this fortress/tower combo. The tower is 3 levels that all open for mini placement- the front gate is removable for when the Uruk-hai bust it in.
If this is not made with hirst blocks, I can only assume you carved each of the blocks individually- your patience alone gets you a 8! having opening gates and movable levels for mini placement get you the extra point.
