The Royal Observatory, home of Greenwich Mean Time and the Prime Meridian, is located in Greenwich Park at the top of the steep hill overlooking the Queen's House and the National Maritime Museum.
In 1675 King Charles II commissioned Sir Christopher Wren to build the Royal Observatory on the site of Duke Humphrey's medieval watchtower. It was named Flamsteed House in about 1720, after John Flamsteed, the first Astronomer Royal.

Greenwich is a borough in London, England, on the banks of the River Thames. Known for its maritime history, it’s home to the Cutty Sark, a restored 19th-century ship, the huge National Maritime Museum, and the classical buildings of the Old Royal Naval College. The modern O2 arena sits on a peninsula to the north. Overlooking peaceful Greenwich Park, the Royal Observatory is the site of the Greenwich meridian line

- The Royal Observatory
- The Cutty Sark
- The Queen’s House
- The National Maritime Museum

The historical importance of these sights has resulted in them being entered into the registry of UNESCO World Heritage sites.
1. The Royal Observatory

2. The Cutty Sark

The Cutty Sark is a British clipper ship. Built on the River Leven, Dumbarton, Scotland in 1869 for the Jock Willis Shipping Line, she was one of the last tea clippers to be built and one of the fastest, coming at the end of a long period of design development for this type of vessel, which halted as steamships took over their routes. See our full blog post on the Cutty Sark
3. The National Maritime Museum

National Maritime Museum, the world’s largest museum dedicated to things nautical, tells the long and complicated history of Britain’s relationship to the sea. The museum houses a huge collection of maritime exhibits including maritime art (both British and 17th-century Dutch), cartography, manuscripts including official public records, ship models and plans, and scientific and navigational instruments.

4. The Queen’s House

Queen’s House is a former royal residence built between 1616 and 1635 near Greenwich Palace, a few miles down-river from the City of London and now in the London Borough of Greenwich. It presently forms a central focus of what is now the Old Royal Naval College with a grand vista leading to the River Thames.
5. The Old Royal Naval College

The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, is described by UNESCO as being of “outstanding universal value” and reckoned to be the “finest and most dramatically sited architectural and landscape ensemble in the British Isles”. Today, it’s hallowed halls are open to visitors.
Planning your visit to Greenwich
Getting to Greenwich is easy, either by car or using public transport. If the weather is good, as it was when we visited, then the most pleasant way of getting there is by boat. As Greenwich has a strong link to British Naval history then this is almost certainly the most fitting way to arrive.
We took a sightseeing boat by Thames River Sightseeing from Westminster pier, close to the Houses of Parliament. This way you’ll get to see many of the historic sights of London along the way and get a commentary to boot. The journey takes about 45-minutes.
Best time to visit London
The best time to visit London is March through May when the temperatures are mild and the city’s parks are green and blooming. However, late spring – along with summer – is also prime tourist season, and hotel and flight prices reflect the surge.
