The temples at Abu Simbel were also rescued from the rising waters of Lake Nasser. This 40 million dollar effort resulted in the temples being cut into manageable size blocks and mode to a location 200 feet higher and reassembled. It is almost impossible to tell that they were moved. More information on the amazing site can be seen at: http://egyptsites.wordpress.com/2009/01/31/abu-simbel/
