Greenwich Observatory History


royal observatory of greenwich

When Europeans started exploring the vastness of the deep blue seas of the world as well as the options of trade with their neighbouring countries, there was a necessity of ample capacity of astronomical information; efficiency to assist cartography, navigation, timekeeping and lastly, how to measure longitude. This was resolved when King Charles II decided to look into investing in astronomy.

On March 4th 1675, the King was recommended by the Royal Commission for the establishment of Britain’s first state-funded scientific institution, an observatory and the assignment of an astronomer. King Charles reportedly called for immediate action and on the same day, John Flamsteed was named ‘astronomer’ and the first part of the Observatory to be built was the Flamsteed House.

In 1818, the Royal Observatory was reassigned to the Admiralty for significant expansion. At present, the Royal Observatory features a record of a working observatory with instruments belonging to the 18th & 19th centuries.

Don't forget to watch the red time ball rise and drop at 1 pm, which takes place every day in the yard. In 1833, the first public time signal in England was broadcasted from the roof of Flamsteed House, by dropping a ball at an estimated time. Ever since then, this ceremony takes place each day at 12.55 when the ball hoisted at the centre of a pole, reaches the top at two minutes to the hour and exactly at 1.00, the time ball drops.

Greenwich Observatory Reviews


"We went with our twin eight-year-old grandchildren and absolutely loved it. There is something magical about standing astride the prime meridian. The science is extremely well explained and the children got a good introduction to time and astronomy. Well worth the £48 for two adults and two children. Greenwich park is lovely and the walk through Greenwich was very interesting. My advice to visitors is to go by boat and get a combined ticket."

“The whole Greenwich area is an amazingly peaceful place, packed with green parks and nice streets. Visit the Observatory, a must see. The nearby maritime museum, too. Allow yourself the whole day for this part of London.“
