Time is relative, proved Albert Einstein, but it is also relevant as visitors to Greenwich, a district of south London, are quick to discover. This district has achieved significance importance for lending its name to the standard used to regulate time and set clocks around the world — Greenwich Mean Time. If you’ve ever tried tried to coordinate a business phone call with participants located around the globe, you’re probably familiar with using GMT to set the appointment time.

A visit to the once small fishing village of Greenwich will likely include a visit to the Royal Observatory and the surrounding grounds which contain the Royal Maritime Museum and the Queen’s House. Collectively called the Royal Museums Greenwich, the area has been designated as a UNESCO World Heritage Site. The Royal Observatory includes Flamsteed House, the original observatory dating back to 1675.

Steeped in maritime and royal history, admission to the Royal Museums Greenwich is free and open to the public, with the exception of certain exhibits. Why not set aside some time (pun intended) to visit Greenwich? It’s sure to be a fun time (pun intended, again).

There are plenty of things to do in Britain, from exploring hip urban locations to relaxing in the lush countryside to exploring miles of coastline. And don’t forget the food, music, art, and fashion. What will you find time for when you visit Britain?
