Overview

As Europeans took to the seas to explore the world and trade with other countries, astronomical information of sufficient quantity and accuracy to aid navigation, cartography and timekeeping was needed, including working out how to measure longitude.
It was this conundrum that would lead to the founding of the Royal Observatory Greenwich.
