American Museum of Natural History

Challenged only by its counterpart in London, the American Museum of Natural History is the largest and most important museum of its kind in the world. More than 30 million artefacts are packed into 42 exhibition halls - quite enough to keep anyone busy on a rainy afternoon. The most popular exhibit is a 50ft (15m) tall skeleton of a barosaurus in the Theodore Roosevelt Rotunda, and there are three more spectacular dinosaur halls on the fourth floor. Other halls include the Hall of Biodiversity, the Hall of Ocean Life, the Hall of Human Biology and Evolution and the fabulous Hayden Planetarium: a 90ft (27m) wide aluminium sphere that seems to float inside a massive glass cube, which in turn is home to the Rose Center for Earth and Space. Those tired of walking can check out the Museum of Television and Radio.
