The Windenburg oldtown hood symbol

Thanks for your awesome input! Hmmm... great ideas but nobody knows for sure?

I found this icon rather different from all the other hood icons, because normally they are quite obvious like animal, bridge or tower. The other icons in Windenburg are a mix, while the countryside hood has windmills, the modern harbor area has another cryptic icon looking like a portal, but I assume it is a reference to one of the sculptures... Oldtown is still in the mist, though... would expect something "old" or a bit of the fortress etc. My first impression was one of these security instalments where you would use a card to pass, but that would not make sense, lol.

@GalacticGal these symbols can be seen on the world map only. They are round - in this case I added the blue background for reasons within my kingdom...

@Gordy I so wish you were right! Windenburg's oldtown would be the perfect habitat for dragons!
