The city occupies an important location, sitting in a natural harbour at the extremity of Haifa Bay on the coast of the Mediterranean's Levantine Sea. Aside from coastal trading, it was also an important waypoint on the region's coastal road and the road cutting inland along the Jezreel Valley. The first settlement during the Early Bronze Age was abandoned after a few centuries but a large town was established during the Middle Bronze Age. Continuously inhabited since then, it is among the oldest continuously-inhabited settlements on Earth. It has, however, been subject to conquest and destruction several times and survived as little more than a large village for centuries at a time. Acre was an important city during the Crusades, and was the site of several battles. It was the last city held by the Crusaders in the Levant before it was captured in 1291.
