BERLIN — Germany's troubled 20th century can be viewed at a glance at its famed Museum Island.
Not in the collections, but in the bullet holes from World War II battles that still pockmark its facades, and the crumbling interiors that deteriorated during 40 years of communist East German rule.
Germany now is in the process of transforming the five neoclassical museums that are clustered on an island in the Spree River into a cultural center to rival Paris' Louvre and London's British Museum.
The complex eventually will unite collections of Greek and Roman antiquities, Egyptian artifacts, 19th century paintings, Byzantine art and Near Eastern antiquities long scattered by last century's wars and political divisions. While construction has been underway for five years, Berlin's financial woes have discouraged anyone from predicting completion.
"We have a concept that is truly unique in the world -- an integrated presentation of 6,000 years of human cultural history," said Gisela Holan, who oversees the building project.
The new plan resembles the concept developed as Museum Island was constructed, beginning with Karl Friedrich Schinkel's Altes Museum in 1830 through the completion in 1930 of the Pergamon Museum with its trove of ancient wonders.
World War II ended the decade-long realization of the vision.
The collections were put into hiding for safekeeping from Allied bombardment and eventually dispersed. Still, some pieces were claimed as war booty. Most were eventually returned, with the notable exception of the Trojan Gold, displayed at Moscow's Pushkin Museum.
The treasures that one day will be collected in the complex range from the 3,000-year-old bust of Nefertiti to the impressive Pergamon altar and ancient Ishtar gate to works by 19th century masters such as Edouard Manet and Paul Cezanne.
"The Museum Island has one of the most significant collections in the world ... in almost all areas," said Bernd Schultz, a Berlin art critic and director of the city's Villa Grisebach auction house. Its range is all the more impressive, he says, because museums elsewhere had a head start. "One should not forget that the Louvre and the British Museum collected over centuries," while Germany -- and the complex -- only came together in the 19th century, Schultz said.
For the Museum Island's post-reunification rebirth, Berlin tapped Austrian architect Heinz Tesar and Britain's David Chipperfield in a bid to balance modernization with the capital's turbulent history.
