The Natural History Museum, London's most iconic specimen is the blue whale model in Hintze Hall—suspended from the ceiling since 2017 (replacing "Dippy" the diplodocus cast).
At 25.2 m, it's slightly shorter than a full-grown female (up to 30 m)—but the hall's architecture constrained scale. It hangs in a feeding lunge pose, throat pleats expanded, revealing baleen plates. Below, interactive displays explore whale biology, acoustics, and conservation.
It's not just a model—it's a manifesto: the largest animal ever, vulnerable to our oceans' fate. Free entry; millions see it yearly. The original 1938 model now resides at the museum's Tring site.
