The Royal Observatory sits atop the hill in Greenwich Park, distinguished by a time ball mounted on the roof of its original Octagon Room. King Charles the Second commissioned this scientific institution in sixteen seventy-five to solve the longitude problem, a puzzle that left mariners unable to accurately determine their east-west position at sea. By tracking the positions of stars, the observatory provided the data necessary to perfect the art of navigation and reduce the loss of ships.
