The inside story
Overlooking the charming Greenwich Park and River Thames in the heart of London, the Royal Observatory is world-renowned for its astronomical discoveries dating back hundreds of years. Commissioned in 1675 by King Charles II of England, the Observatory is a unique attraction that hosts over two million tourists a year.
The Royal Observatory in Greenwich became the first purpose-built scientific research facility in Britain. Along with gathering information on stars, King Charles II wanted to create something in order to help sailors with navigational purposes since international trade was becoming popular.
