The layout of the columns looks like this:

On top of it come surrounding quarry stone steps and above any number of stone bricks, as a capital (the thing at the top of a column) I have taken the same as the base (the thing at the bottom of a column). The floor is a check pattern of bricks and cracked bricks.
The vault looks like this in cross section (here reconstructed with sandstone):

The columns have been built in such a way that you can go up inside with a ladder.
