Walk through famous places

Rome's arena, Barcelona's cathedral, a canyon, a Korean palace, an Inca town, a sequoia forest, an army of clay, a buried city and the clouds of Jupiter.

They run roughly from ancient to modern, then to the natural giants, and the walk ends beyond Earth in the cloud tops of Jupiter.

Each of these exhibits is a place you can walk through, built from measurements and maps. In the Colosseum you can go under the floor to the lifts that raised animals into the arena. In the Sagrada Família the columns branch like trees above you and coloured light crosses the floor as the day goes on. In Gyeongbokgung the stones in the courtyard told every official where to stand.

The later places add time. The Grand Canyon is a stack of rock layers that records a billion years, Machu Picchu hides most of its work underground, and a sequoia forest keeps a record in its rings. The Terracotta Army was once painted, Pompeii has a clock that runs to the last morning, and Jupiter shows its famous spot shrinking. Look for what you cannot see from the usual photograph, such as foundations, drains, lifts and layers.

    Walk down the Grand Canyon rock layers

    Fly over Jupiter's clouds and the Great Red Spot

    In the late 1800s the Great Red Spot was about three Earths long; Hubble now measures it at about one. Float over it with Earth beside you, then sink 132 km into the clouds with the Galileo probe.

    Drag Year (Great Red Spot) from 1880 to 2024 with Earth for scale and watch the spot shrink.
