Since the days of the Great Roman Empire, the Tiber River has been known as one of the most iconic waters that surrounded the seven hills of Rome. I captured this picture from the top of Castell de Sant Angelo, which was a fortress first commissioned by the Roman Emperor Hadrian back in the 2nd century. Standing on the top of the fortress, I had an overview of the entire capital as well as the river that wrapped its body across the city like a serpentine. Throughout history, the Tiber river was used for importing construction resources into the city, such as marble and timber. The river that would start from the top of the Apennine Mountains in Emilia-Romagna and end in the Tyrrhenian Sea was not controlled with any significant hydraulic principles to prevent floods such as the ones found in Rotterdam or Amsterdam. Yet, several Popes throughout the history tried to better the navigation of the river by constructing sites around the mouth of the river to make traveling safer and more efficient. Another interesting fact about the Tiber River and the surrounding waters is that 65% of its fish species are identified as exotic. The preservation of the river’s environment is significant and has been marked as an important ecological corridor for environmental preservation. With dozens of bridges connecting across this historical river and bike paths stretching all around the waters, Tiber river is one of the most magnificent rivers I have ever seen. A sight to truly appreciate and protect as it was preserved for thousandths of years before us.
