Historic ship Cutty Sark and Royal Observatory Greenwich are open late every evening during the summer months, giving you a chance to enjoy these special places for longer.

Take more time to explore the sites, avoid the peak visiting times, and make the most of British Summer Time at Greenwich.

The Royal Observatory is the home of Greenwich Mean Time and the birthplace of British astronomy. Situated at the top of the hill in Greenwich Park, it’s the perfect place to enjoy the beautiful evening light.

Or you could step aboard the famous tea clipper Cutty Sark, take in views of the Thames from the Main Deck before heading to a riverside pub to watch the sun set.

If you want to visit both sites, why not book a Royal Museums Greenwich Day Pass? It’s our best value ticket and gives you entry to both the Royal Observatory AND Cutty Sark.
