Small, well-preserved, leaning on the edge of a desert plain of the Libyan Sea in Sfakia around the mountains, Fragokastelo unfolds even today the skein of history, a story full of memories and mysteries. The "castle of Drosoulites" was built by the Venetians in the period 1371-1374, aiming to protect them from Sfakians, who were lead by the six brothers Patsis who constantly bothered occupiers, who could not complete the project. Other Venetians killed the six brothers by treason, according to tradition. On the other hand, in order to gain time, Venetians used for the construction of the fortress ready carved stones from the adjacent Nikita ruined ancient city.
