Justinaus in Serdivan

You're standing at the Sangarius Bridge, also known as the Bridge of Justinian. Locals call it Beşköprü. Just look at the length of it: around 430 metres of limestone, almost ten metres wide and up to ten metres high. This is a late Roman bridge, built on the orders of Emperor Justinian the First. He wanted better links between his capital, Constantinople, and the eastern provinces of his empire.
