http://www.msnbc.msn.com/id/43576005/ns/travel-destination_travel/ Berlin has unveiled its latest tourist attraction: a futuristic box that will sit for the next few years on a downtown square where a replica Prussian palace is to be built. The so-called Humboldt Box rises some 92 feet (28 meters) above one end of the capital's Unter den Linden boulevard, opposite the neoclassical Museum Island complex. The roughly hexagonal silver-and-blue building offers spectacular views and hosts exhibitions on the planned palace — construction of which has been delayed as part of an austerity package. It is now slated for completion in 2019. Officials say the box's modern appearance was a deliberate choice. Hermann Parzinger, who heads the foundation that oversees Berlin's museums, said Tuesday visitors may be "surprised by the architecture ... and want to see what's in there."
