Royal Observatory Greenwich is a scientific institution founded in 1675 by King Charles II at Greenwich in London. The establishment of the Observatory was integral to the development of astronomical science and navigation, serving as the principal site for determining longitude at sea through precise astronomical observation. The original building, designed by Christopher Wren, exemplifies late seventeenth-century scientific architecture and housed the instruments and accommodation necessary for the Astronomer Royal to conduct observations. The Observatory became the reference point for the Greenwich Meridian, adopted internationally as the prime meridian in 1884, fundamentally shaping global timekeeping and cartography.
