Ayup.

The pool goes VERY deep, and it's a steep incline, perfect for diving if you do it off the deep end. It would be pretty big by modern standards, considering every block in minecraft is a meter each, which translates roughly to a yard.

I went for the standard castle look for the lower 3 levels and the roof of the rock castle, including the turrets (or I think those intrusions that protect from enemy archers are called turrets) and the style of the windows-using iron bars instead of glass. The weird modern stuff comes in at the 4th floor, which leads to an inverted iron castle, though inside the style is mostly the same to the standard rock one. In fact, it would only take a few changes to the balcony and railways, and then one could flip the whole structure upside down without any integrity loss.

Just, don't question how it's all stable on the 4th floor and how the stairwell doesn't just crush in on itself. Magic is involved. Heavily.
