Lying along the north coast of Crete is Chania, the second largest city of the island. Chania is bordered by endless stretches of seashore, with inlets and islands of exotic beauty and sandy beaches tucked away at the foot of the island's forbidding mountains. This is a self-sufficient region that is blessed with rich flora and fauna, as well as impressive gorges, holy caves, rivers and lush, green plains blanketed with citrus groves. The city of Chania is comprised of two sections, the old town and the larger modern city. Situated next to the old harbor, the old town is the focal point from which the urban area has developed. Some of the eastern and western parts of the original old Venetian fortifications from the 1500s that surrounded the town have survived and can still be seen.
