The full review
Most visitors come specifically for the Mapparium and stay for the rest. Built in 1935, the globe shows national borders as they were at that exact moment — Persia, the British Raj, the USSR — preserved unchanged. The acoustic effect on the bridge through the middle is genuinely strange: speak normally and you'll hear yourself echo back amplified, while a whisper from across the globe arrives clearly.
