Siege of Candia
The siege of Candia (modern Heraklion, Crete) was a military conflict in which Ottoman forces besieged the Venetian-ruled city. Lasting from 1648 to 1669, or a total of 21 years, it is the second longest siege in history after the siege of Ceuta; however, the Ottomans were ultimately victorious despite Candia's resistance.
