Stations and Wall sections:

Some of the Wall sections are thick with interior work which makes them ponderious but not so roomy.  Possibly the added thickness was for mass to ward off and opponents artillary, more of a defensive position than the others which might have been for storage or troop quarters.

Older unrestored station section.

Note the footer pad for a column support as opposed to the heavy vaulting above.
