Six onion-roof towers supporting heavens

[Stefan Wirtz_2]

I don't understand that; the location of the towers in ROS is central, and if they are supposed to symbolize the temples/mosques of Jerusalem, for example, then everything is fine, isn't it? What do you mean by peripheral “onion towers”?

Those towers in the red circles appear to be more part of the town walls than being anyhow in a center of it:



This map is said to be rather realistic.

The 2 towers in blue circles are parts of important temples and could be understand somehow as "central";
but in total, there are 4 really onion-like buildings, and several domes which cannot be mistaken for "onions" anyhow.

Apart from that, VMS roundel shows rather weird understanding of "towers", the most-right is the strangest.
Town walls, buildings or streets are not shown (symbolized or realistic) at all, only an outer ring of tower-like tips could be recognized as that - far away from the center.
