Crete's largest city and Greece's fourth, built over the Minoan port that served Knossos, the Bronze Age palace 5km inland where the Minotaur myth took root. Venetian Candia held out under Ottoman siege for 21 years (1648-1669), one of the longest sieges in history, and the harbour fortress Koules still stands from that era. FORTH, one of Greece's leading research foundations, and the University of Crete give the city an institutional weight the rest of the island lacks. Nikos Kazantzakis Airport carried over 10 million passengers in 2025, Greece's second-busiest after Athens, with Sky Express and Bluebird Airways based here year-round rather than only through the tourist season.
