BERLIN, 19 JULY - An excavation will have to be carried out to protect the Bundestag building in Berlin from possible terrorist attacks with trucks. In the part in front of the Parliament a ditch 10 meters wide and 2.5 meters deep will be built and on the sides a protective net will be placed. The work will proceed in parallel with the construction of a visitor center from which tourists who want to visit the Foster dome can reach the Reichstag through a tunnel. The estimated cost is 150 million euros.
