Procuratie Vecchie

Well as much as I enjoy researching longer than needed, I still cant seem to find out how many windows/arches are on the long side of  Procuratie Vecchie (the building I am recreating.)

I have found an image which shows the back which has 2 floors, 15 arches on top floors.

I have found some better images as well which will help out with getting detail on the building as well so I feel like I can get a bit farther with this project in regards to starting to model.
