This is the beginning of my isengard build Im trying to make it as close to the book as possible, the radius is 817 blocks or 817m about a half mile.

The tower will be ~178 blocks or 178m whatever floats your boat

Slight change to height i will give height when i figure it out, to make the top of the tower look better.

High will be around 191 blocks high
the wall is getting a major revamp aswell pictures will be posted soon

Im back to working on this massive project stay tuned for more updates.
