Well here we are almost 3 years after this build.
I just realized that I hadn't included the final dimensions here!

The Stadium is 454 Blocks Wide, 754 Blocks Long and 127 Blocks high from the foundation (3 levels underground) to the top.

Sadly I never went back in to finish the last details.

I took a year off MC and haven't touched my Classic server since I came back.

Maybe one day i'll load it back up and finish the details.
But more likely i'll simply rebuild it in Retail.
