Greenwich is the home of time, a World Heritage Site, and jam packed with excellent activities to fill your stay. Step aboard the Cutty Sark, pay a visit to the Royal Observatory and straddle the Meridian Line, wander the grounds of Queens House, and visit one of the finest maritime museums in the world. They’re just a handful of things to do in Greenwich. You’ll need a hefty lunch of jellied eels if you’re planning on seeing them all in one go.
