Earth Hall and Stegosaurus

The Stegosaurus in the Earth Hall

Meet our incredible dinosaur specimen, the most intact Stegosaurus fossil skeleton ever found. At three metres tall and almost six metres long, it's a dramatic welcome to Earth Hall.

Here you can feel the drama of our planet. Surrounded by a celestial map on the gallery walls, explore gems and minerals, including a piece of moon rock.

The escalator is currently under maintenance, but you can still get up to the first and second floors of the Red Zone via the stairs and lifts.
