Royal Observatory Greenwich

London

Explore the birthplace of modern timekeeping at the Royal Observatory in Greenwich. As you step onto the historic Meridian Line, place one foot in the eastern hemisphere and the other in the west—an unforgettable moment that helps illustrate how Greenwich came to define the Prime Meridian back in 1884. Inside, uncover stories of space, stars, and groundbreaking astronomical research that shaped our understanding of time and navigation. Leave with a renewed sense of wonder for our vast universe and maybe even fresh inspiration for your own travels.
