A Guide to the Royal Observatory, Greenwich

The Royal Observatory is one of the most famous historic features of Maritime Greenwich - a World Heritage Site. Situated where east meets west, the 'home of time' has been at the heart of nautical astronomy since the late 17th century, when Charles II commisioned Christopher Wren to design a building in which the first Astronomer Royal - John Flamsteed - could determine the 'longitude of places'.
