About The Royal Observatory, Greenwich:

Perched atop a hill in Greenwich close to the banks of the River Thames, the Royal Observatory is a place where you can officially straddle the two halves of our home planet. The exact line of longitude might be 102 metres further east according to modern measurements, but it's the historicity of the site and its many wonderful attractions that draw in curious visitors by the thousand.

The Royal Observatory Greenwich was where, in 1851, Sir George Airy established the internationally recognised Prime Meridian, a line of longitude which, along with the antimeridian, divides earth into its eastern and western hemispheres. It was borne out of King Charles II's desire to improve the art of oceanic navigation, an undertaking that required precise knowledge of the movements of celestial bodies and fixed stars. To achieve this he had the Royal Observatory commissioned in 1675. Its location atop a hill in Greenwich Park was chosen by renowned architect Sir Christopher Wren, and its construction was completed one year later in the summer of 1676.

For over 250 years the Royal Greenwich Observatory played a significant role in the development of astronomical and navigational sciences. It was only after the Royal Observatory moved to Herstmonceux during the mid-20th century, and then dissolved in 1998, that the facilities at Greenwich became a public museum.

Today tens of thousands of visitors from all across the globe make their way up Greenwich Park Hill to stand on the world famous Meridian line. This popular monument is accompanied by many more fascinating attractions spread throughout the historic site. Meet the Great Equatorial Telescope in the Onion Dome (the largest instrument of its kind in the UK), marvel at the Observatory Museum's extensive timepiece and navigational instrument collection, and enter Flamsteed House, the historic home of the Astronomers Royal.

Greenwich Observatory is also well worth visiting on a sunny day for its panoramic views of the City of London. One of the easiest ways to get there is by river, a bonus as this ticket includes 24-hour access to London City Cruises' hop-on hop-off boats. Simply disembark at Greenwich Pier and walk 10 minutes or so towards the hill.
