Neil MacGregor began his journey through 600 years of German history at the Brandenburg Gate in Berlin, and ends it at the Reichstag, seat of the German Parliament. These two extraordinary buildings, only a few hundred yards apart, carry in their very stones the political history of the country.
Neil talks to architect Norman Foster, who in 1992 won the commission to restore the Reichstag, when Germany's Parliament returned to Berlin in the wake of re-unification.
