A slice of history
The observatory was founded in 1657, a few kilometres from London, with the objective of creating a universal system of navigation for the whole planet. Years later the meridian line, 0 degrees, was set in Greenwich, making it the centre of world time and the dividing line between east and west.
The observatory is one of the most important and interesting scientific centres in the world, and the home of any number of great advances in the history of science.
What to expect
The Greenwich Observatory is the centre of world time, and here you can see the first Tompion Clocks, the halls from the 17th century and discover the very first telescope.
Without a doubt the main attraction is the meridian line, where you'll have the unique opportunity to stand with one foot on the east side and another on the west of the planet.
