Area of Ostružnica was a location of the Long Bridge, the first permanent bridge in Belgrade's history. As the opposing, Syrmian side across the Sava was a vast marsh at the time (modern New Belgrade), the bridge didn't stop at the bank but continued for some length above the swamp.
The Ostružnica area was a site for the Long Bridge, which represented the first permanent connection in Belgrade's history. The opposing Syrmian side across the Sava River featured an extensive wetland (now New Belgrade) at that time, leading to the bridge extending into the marsh beyond the riverbank.
