February 18

So it looks like the second floor starts at 35'8 and the doors possibly are from 5' z to 20'4" z. 15 foot doors?

Second level columns. 

Parapet is 2.5', column is 15', architrave is 3'.
I know it looks blocky, but I just trying to flesh out some known objects that can be refined later.

So on to the columns on the colonnade.

Wouldn't you know it...there are 36 of them, around 180 degrees of arc. 5 degs for each one.

Make these columns 15'.

The tops of columns are at 52' 1 9/16" height.
