The Ancient city of Kydonia on Crete (insular Greece) had a bishop no later than the second Byzantine rule (961 AD – 1204 AD), when it was given the modern name of Chania.

The Venetians (and shortly the Genoans) who conquered Crete firmly established a Latin diocese. It was suppressed only in 1700.
