The SS Oria was a Norwegian steamer that tragically sank on February 12, 1944, resulting in the deaths of approximately 4,095 Italian prisoners of war, along with 21 Greeks and 15 Germans. This incident stands as one of the most catastrophic maritime disasters in history, and it remains the deadliest maritime disaster involving the sinking of a single vessel in the Mediterranean Sea. The event is particularly significant for the Lavreotiki Municipal Unit, as it underscores the region's historical maritime legacy.
