Side Projects are Rarely Successful

I started building this, my plan was a little too ambitious, I wanted a castle that covered around 90,000 blocks.  However, the plan needed 4 turrets, and this is my evolution of a single turret.  I doubt ill be able to build four more.  Here are pictures I took every few hours.  The base of the tower is 30x30 and surrounded by a three wide moat.
