They Started Building a Subway in Istanbul. What Was Underneath Delayed It by Four Years

In 2004, construction crews digging a train station in Istanbul broke through into the largest commercial harbor of the Byzantine Empire. The Harbour of Theodosius had been buried under the city for five centuries, completely forgotten. Over nine years, archaeologists extracted thirty-seven shipwrecks dating from the fifth to the eleventh century, the largest collection of medieval ships ever found at a single site. Beneath the harbor floor, they found something even older. A Neolithic settlement from 6500 BC with preserved human footprints pressed into mud eight thousand five hundred years ago. The Marmaray project was delayed by four years. It was supposed to build a train station. It built a cross-section of eighty-five hundred years of civilization instead. Hope you find it as interesting as I do!
