Secret Berlin

Wander around the hotel lobby where a glass floor reveals excavations of the old medieval town; take a seat in an amphitheatre where animal dissections once took
place; let yourself be moved by the sounds of the largest pipe organ, still used today to bring silent films to life; take a break in one of the few well-preserved Baroque
vaults housing coffins fitted with windows; climb onto a bunker that contained anti-aircraft guns during the Second World War and accept a Russian soldier's invitation to admire it from within; take a dip in one of the most beautiful bathing spots built during Europe's Art Nouveau movement; enjoy a stroll under the Spree river; go see the very first computer (designed by a Berliner) or the first synthesizer of East Germany; scale the mountain of rubble where a Skiing World Cup race was held; station yourself at the peak of the artificial hill where aviation pioneer Otto Lilienthal made his first attempts at flight; and grab a bite on the island in the Havel river where Werner von Braun launched his first rocket.
