The tour will lead you through Flamsteed House, allowing you to follow in the footsteps of the Astronomers Royal. Visit the Octagon Room, designed by Sir Christopher Wren, which is one of the best-preserved Wren interiors in London. Explore Harrison’s clocks, the groundbreaking inventions that changed the world. Discover the Shepherd Gate Clock, mounted outside, which was the first clock to publicly display Greenwich Mean Time. Learn about the remarkable discoveries of renowned scientists and inventors associated with the Royal Observatory, including Harrison, Newton, Halley, Bradley, Maunder, Harrison, Airy, and Einstein.
The bright red Time Ball atop Flamsteed House is one of the world’s earliest public time signals, first used in 1833, and it still functions today. Be sure to see the Great Equatorial Telescope, housed in the iconic large onion dome, which provided astronomers with new views of the universe over a century ago.
Located within the UNESCO World Heritage Site of Maritime Greenwich, the National Maritime Museum and the Queen’s House are both a short walk from the Observatory and offer free admission. The Cutty Sark, the world’s only surviving tea clipper, is now an award-winning museum and visitor experience, making it a must-see when visiting Greenwich.
