This Castle was built in 1371, during the four and a half centuries of Venetian rule.In 1669 Crete was conquered by the Turks, who remained there until 1898.
During the period of Turkish occupation there were many revolts, one such taking place at Frangokastello on 18 May 1828. The resultant bloody battle, involved 800 Turks and 700 Cretans.
A strange phenomenon is said to occur here on a morning each year, between 17 and 30 May, just before sunrise. A shadowy column of armed black figures leaves the ruins of a nearby church and proceed to march along the castle walls. These figures, (known as "dew men", only appear for 10 minutes, and are believed by the locals to be the souls of the dead Cretans.
This occurrence has been investigated by scientists, who could only explain it as some extraordinary mirage originating in Libya, almost 250km away. To the locals this seemed impossible, as the distance is surely too great, and the dates correspond with the anniversary of the battle.
