I have also found out that contrary to its nickname of Roman Well, it was actually built between 1717 and 1731 by the Austrians who ruled Belgrade at that time. The confusion came when the Serbian rebels, who took back Kalemegdan fortress from the Ottomans in the 19th century, believed mistakenly that all constructions dated back to Roman times.
To top things off, it's not really a well at all, but rather a cistern. The water within does not come from an underground spring, but is simply stored there.
It looks fat and chubby here, but that's thanks to my fisheye lens.
Not everything is
What it appears to be
Seek the truth within
