 A leading Greek foundation on Friday unveiled a sprawling new park, opera and national library in southern Athens designed to "give hope" to a country brought low by a six-year economic crisis. The 1,400-seat opera, library and adjoining park designed by famed Italian architect Renzo Piano cost nearly 600 million euros ($680 million) and took eight years to design and build. The new Stavros Niarchos Cultural Center, expected to fully open in mid-2017, occupies 20 hectares (50 acres) overall near the coast of Faliro in southern Athens. / AFP / LOUISA GOULIAMAKI        (Photo credit should read LOUISA GOULIAMAKI/AFP via Getty Images)
