Full Description

The Royal Observatory in Greenwich Park

The Royal Observatory was founded by King Charles II in 1675 to help sailors find their way at sea by studying the stars and the moon. The first Astronomer Royal, John Flamsteed, worked in the elegant brick building on the hill that Christopher Wren designed, Flamsteed House, and its red time ball still rises and falls each day.

A visit to the Royal Observatory suits anyone who likes real history and science. Your Royal Observatory Greenwich tickets cover the historic buildings, the Prime Meridian courtyard and the galleries, and the hilltop position gives sweeping views to the Thames, Canary Wharf and the City.

The Prime Meridian line and Greenwich Mean Time

The brass strip in the courtyard marks the Prime Meridian, the line of zero degrees longitude. In 1884 an international conference chose the meridian through Greenwich as the world's reference, and Greenwich Mean Time became the basis for time zones. Standing with a foot on each side of the line is the classic photograph of any Prime Meridian visit.

Expect a short queue for the photograph in busy hours, and go early on a weekday for shorter waits. If you are wondering whether the Prime Meridian is worth seeing, the answer is yes, because the surrounding displays explain clearly how the line was chosen and why it matters.

Harrison's clocks, the great telescope and the astronomy galleries

Inside, the galleries tell the story of the longitude problem. John Harrison's marine timekeepers, built in the eighteenth century, allowed ships to calculate their position accurately and are among the most admired objects in the collection. The Octagon Room shows how astronomers observed and worked in Wren's original design.

Under the onion-shaped dome stands the Great Equatorial Telescope, the largest refracting telescope of its kind in Britain. The astronomy galleries feature a huge meteorite that formed billions of years ago, plus displays on planets, stars and the night sky. The planetarium show and a live guide are not part of this ticket.

Getting to Greenwich and how long to spend

If you are asking how to get to the Royal Observatory Greenwich, take the DLR to Cutty Sark, a train to Greenwich station, or a river bus from central London. From the town centre it is a steady uphill walk of about fifteen minutes through Greenwich Park.

Plan roughly two hours, and more if you also want the Cutty Sark, the Queen's House or the National Maritime Museum at the foot of the park. The best time to visit is on a clear morning for views and lighter crowds, though the galleries remain rewarding in wet weather.
