The Royal Observatory Greenwich is the famous location of the Meridian Line, dividing the eastern and western hemispheres to create the timeline we know today as Greenwich Mean Time (GMT). Stand with one foot on each side of the line and be split between both sides of the world. It may seem unimportant, but this invention is one of the most influential of all time.
Take a look inside the museum to find out the history of GMT and understand why the world's time systems are so important. Before international conventions, every place configured their own time, and as communications between countries grew, a new time standard was necessary. Imagining our world without time is impossible!
Slip into the planetarium to join a journey through the solar system, starting right from the Big Bang. Relax in a comfy chair and let the knowledgeable staff narrate your way past planets and galaxies, linking this far away world to how we first conceptualized time.
The observatory also houses one of the world's largest telescopes, the Great Equatorial Telescope, which kept Britain the forerunner of astronomical discovery. Scientific discoveries here changed the world as we know it, most notably the methods developed to map the seas which in turn helped explorers like Captain Cook to journey to new lands.
See the iconic red ball on top of Flamsteed House, one of the earliest public time signals. First used in 1833, it rises from the bottom of its mast at 12:55 before falling back down at precisely 13:00. Time your visit to catch it drop! After your exploration into the world of time, take a moment to rest and look over the view of the city skyline, Greenwich Royal Park and the River Thames from the top of the observatory. This is a not-to-be-missed experience for science and history lovers.
