Royal Observatory Greenwich is a scientific institution founded in 1675 by royal charter of King Charles II, located on a hill within Greenwich Park in south-east London. The original building, the Flamsteed House, was designed by Sir Christopher Wren and constructed between 1675 and 1676 to house the Astronomer Royal and the astronomical instruments necessary for determining longitude at sea. The Observatory became the prime meridian for world timekeeping and geography following international agreement in 1884, establishing Greenwich Mean Time as the global standard. The site has been substantially developed over subsequent centuries with additional buildings and instruments added to support increasingly sophisticated astronomical observation and research.
