Heraklion is the largest city on the Greek island of Crete, as well as the administrative capital of the region. It is situated roughly in the middle of the island's northern coast. With a population of just under 150,000, Heraklion is home to about one in four Cretans. Famously, the city underwent a 20+ year seige by the Ottoman Empire in the late 17th century, which is believed to be the longest in history.
