    Sir Jonas Moore presented the idea of building Royal Observatory to King Charles II in 1674 . Finally construction of Royal Observatory started in 1675 after Moore was given that responsibility by King Charles II. The first building of Observatory, Flamsteed House, was designed by Sir Christopher Wren along with Robert Hooke and it became the first scientific research facility in Britain.

    Royal Observatory was initially used to keep scientific instruments which Flamsteed utilized to work on Stellar tables. Later on, numerous other things/tasks were also included; such as Her Majesty's Nautical Almanac Office and time keeping for navigational and astronomical reasons.

    In 1850, Royal Observatory established Prime Meridian and became the basis for measurement of longitude, the Greenwich Mean Time. There was previously no standard base for time dimension and every town used its own local time. However, with the expansion of railway and communication networks in 1884, Greenwich Meridian started being considered a Prime Meridian of the World.

    After World War II in 1947, the decision was taken to move Royal Observatory to Herstmonceux Castle. After the location of Royal Observatory changed, the ownership of Flamsteed House was transferred to the National Maritime Museum in 1960. Later, several renovations took place over the next seven years. With the passage of time, scientific research collections grew and then in 1998, Royal Greenwich Observatory was relocated to Cambridge and the site became known as the Royal Observatory, Greenwich. Major refurbishment programs took place in 2005 at the Royal Observatory Greenwich in which Planetarium, astronomy and time galleries and an education centre were constructed  and in 2007, it finally opened up for the public and visitors.
