Berlin rewards visitors who prioritize ruthlessly, since the city spans centuries of upheaval in a compact core. The Brandenburg Gate remains the essential starting point, a symbol of division and reunification alike, while the nearby Reichstag Building offers a glass-domed view over the government quarter. The Berlin Wall Memorial preserves an actual stretch of the barrier along with the death strip, giving the Cold War era physical weight rather than abstraction. For deeper context, the Topography of Terror documents the machinery of Nazi rule on the site of former Gestapo headquarters. Together these stops trace Berlin's modern history efficiently, making them the smartest use of limited time.
