Want to walk where history actually happened? We're walking the actual sites, not museum reconstructions. Seven stops. One hundred and seven minutes. You'll stand where families were torn apart, where desperate people dug tunnels under machine-gun fire, where the remaining Wall segment shows bullet marks and shrapnel damage. The Topography of Terror sits on the unmarked grounds of the former Gestapo headquarters. Then there's the concrete barrier still bearing the scars of violence. And the escape tunnels? Tunnel 57, Tunnel 29? Tunnel 57 had a 60% success rate; Tunnel 29 collapsed during construction. This isn't a lecture. It's an immersion. Moderate walking, plenty of pauses to absorb what you're seeing. Wear comfortable shoes; the tour includes standing in reconstructed tunnel spaces.
