I'm not sure if this is the best board for this question, but could not find a better one.
So I'm about to do some FRUA wallsets for library wich is - according to its description - built in a colonnaded Chessentan style. My problem is that I don't really know how this style looks like. Searching for references based on its cities did not yeald any result. The only one I found is a picture of Tchazzar:
wich seems like something like a Greek or Roman style. Can someone confirm this?
