720 The National Geographic Magazine r -A K Alfred Cook, U. S. Army Engineers Down the Hopper, Below Water, Goes Concrete to Restore Piraeus Harbor Germans blew up more than a mile of quay, sank cranes and hulks where they would do the most harm. United States Army Engineers began directing repairs in 1947 (opposite page). Today the port and dry docks are as good as ever, but landing costs are high because, instead of being unloaded directly on the quay, most cargoes are transferred to lighters which carry them to shore. So vital was the port of Piraeus to ancient Athens that the two cities were connected by the Long Walls, fortified highways, long since quarried away.
