Royal Observatory Greenwich

Home of Greenwich Mean Time and the famous Prime Meridian of the World. Sir Christopher Wren's Royal Observatory is also a museum of time and astronomy. Built for the purpose of finding Longitude at sea, you can still see where the Astronomer's Royal used to live and work. The Observatory is also home to London's only live planetarium (opening in May 2007), where Royal Observatory astronomers provide you with a magnificent introduction to the mysteries and wonders of the world beyond our night sky.

Permanent Collection

See John Harrison's famous marine chronometers in the Time galleries. Try your hand at being an astronomer, guide a space mission or touch a meteorite that is over 4.5 billion years old. Answer all your questions about the universe in the new modern astronomy galleries.
