First, you could stand across the world-famous Meridian Line, with one foot in each hemisphere. Set in a charming historic building originally made for the Astronomers Royal with a modern planetarium alongside, the Royal Observatory is a great place to discover the stories of space and how we have found out what we know. Visit and you will learn about the past, present and future wonders of astronomy, space and the stars. Enjoy dramatic views of London across Greenwich Park, the City of London and the River Thames. 

Then, visit the Cutty Sark and experience what life was like on board a true survivor of the seas. Venture aboard and beneath one of the world’s most famous ships – the last surviving tea clipper, and the fastest and greatest of her time. Built in 1869 to carry tea back from China, Cutty Sark survived high seas, storms and mutiny, and travelled far and wide to almost every major port across the globe. 

Or you could do it the other way round – it’s entirely up to you!
