Tel Yafo (Jaffa Hill) rises to a height of 40 meters (130 ft) and offers a commanding view of the coastline; hence its strategic importance in military history. Archaeological evidence shows that Jaffa was inhabited some 7500 years BCE. Jaffa's natural harbor has been in use since the Bronze Age. Jaffa is mentioned in an ancient Egyptian letter from 1440 BCE.
