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.
UK: London – Thames River
Like most of the great cities of the World, London is bisected by a great river, in the cast the River Thames. The Thames is part of the longest river in England, it has 45 locks, is home to over 25 species of fish, boasts three areas of outstanding natural beauty and it’s the only river in Europe to have a national trail follow its entire length.
Starting as a small trickle in the Cotswolds the River Thames travels over 210 miles through the heart of some of England’s most picturesque towns, right into the centre of London and eventually, out into the North Sea.
The River Thames has been the hub of commerce for London ever since the city sprung into existence and has played a key role in many of the historical events that have taken place in the United Kingdom’s capital. A boat trip along this famous river will take you past many of London’s greatest sights.
Boat cruises
Several companies offer boat cruises, from hop-on-hop-off style to high-speed trips to dinner cruises along the Thames.
Uber Boat by Thames Clippers provides high-speed service along the Thames. This River Bus service currently serves 24 piers, from Putney Pier in the west to Barking Riverside Pier in the east. A partnership with Uber means that you can get your tickets through the Uber App.
For a more leisurely experience on the Thames, you can try the Bateaux London, With this cruise, you can have a meal, enjoy some music and explore the sights of London from the river.
We decided to take the more traditional and less expensive river cruise with City Cruises. For $22 you get a full-day hop-on-hop-off ticket. With a hop-on hop-off Thames river cruise you can join the boat tour at any of the four piers (located at Greenwich, the Tower of London, the London Eye, and Westminster)
The cruise
We joined the boat at Westminster pier. Before starting your cruise you can visit the Palace of Westminster (the House of Parliament) and the Westminster Abbey


On the opposite side of the Thames from the House of Parliament is County Hall, a listed building and the former headquarters of the Greater London Council (GLC). Today, it is an entertainment centre, housing Shrek’s Adventure London, the SEA LIFE London Aquarium, and the Namco Funscape amusement arcade.
The building also houses two hotels—a 5-star Marriott Hotel and an affordable Premier Inn.
Right outside the old County Hall building is the London Eye.

The journey continues down the Thames past the Southbank Centre and the famous OXO building. A short distance further on is the Globe Theatre, a reconstruction of the theatre that sat close to this location during the lifetime of William Shakespeare. Today, the theatre puts on Bard’s plays during the summer months.

Just after passing the Globe, a reminder of London’s past, you will see one of the newest additions to London’s skyline, the Shard (or Shard of Glass). This 72-storey skyscraper was inaugurated in 2009. The Shard stands 309.6 metres (1,016 feet) high and is the tallest building in the United Kingdom, and the seventh-tallest building in Europe.

There are 35 bridges which cross over the River Thames from Tower Bridge to Hampton Court Bridge. Not all the bridges are old – in fact, many are quite modern, including London Bridge. As the boat cruise approached the square mile of the City of London, we saw the remains of a bridge that isn’t there anymore – the old Blackfriars railway bridge.

The most recognisable bridge in London is without a doubt Tower Bridge. There are some people who think this is London Bridge – it isn’t – that is a boring, modern bridge upstream.
Tower Bridge’s gothic design makes it feel really old but this suspension bridge was built between 1886 and 1894.

Right next to Tower Bridge is the Tower of London. Tower of London, by name the Tower, royal fortress and London landmarks. Its buildings and grounds served historically as a royal palace, a political prison, a place of execution, an arsenal, a royal mint, a menagerie, and a public records office. It is located on the north bank of the River Thames. The City Cruises has a pier next to the Tower of Londo, so you can hop off here and visit Tower Bridge and the Tower of London.

From the Tower of London, the boat cruise heads east along the River Thames passing several interesting pubs and buildings, and the modern development of Canary Wharf, with over 300 shops, cafes, bars and restaurants, a year-round events programme, one of London’s biggest roof gardens

The final stop of the River Cruise is the delightful district of Greenwich with its market, and interesting shops, bars and restaurants.
There are a number of interesting places to visit in Greenwich including the Cutty Sark, a historical British clipper, the National Maritime Museum, the Royal Observatory, the Naval College and the Queen’s House.
