The Royal Observatory, Greenwich is the basis of modern timekeeping. It is a historical observatory commissioned in 1675 by King Charles II which gave its name to Greenwich Mean Time. It is located just out of London and should be on anyone's bucket list when visiting the British capital. It is an overlooked attraction, that should be part of what everyone should do in London on their first trip.

While in Europe, visit the Top of Europe and the Sphinx Observatory high in the Alps in Switzerland. It is the highest observatory in Europe and is even reachable by train thanks to bewildering Swiss engineering. See how these observatories compare with being historical in London or picturesquely set in the Alps.

Royal Observatory Museum

The buildings that were the observatory are now a museum exhibiting astronomical and navigational tools. Some of the notable exhibits include John Harrison's pioneering chronometer (known as H4), as well as his three earlier marine timekeepers. These are actually now the property of the Ministry of Defence. There are many other horological artifacts are displayed that document the history of precision timekeeping for navigational and astronomical purposes. One will also see the 28-inch equatorial Grubb refracting telescope of 1893.
  • Opening Hours: Open Daily from 10.00 am to 5.00 pm
  • Great Equatorial Telescope: The UK's Largest Historic Telescope

At the observatory, one will also walk the line of the famous Greenwich Median that's clearly marked on the pavement.

Visit The Cutty Sark Ship

One of the fun attracts is the Cutty Sark. Visitors are able to climb up the famous ship's masts and view the Thames and London with a sailor's eye view.

From the Main Deck, climb the ship’s 'ratlines' (rope ladders) and then make one's way up into the rigging, just as hundreds of sailors did during Cutty Sark’s long and fabled career at sea. One then descends with a  zip-line. The ticket for the rig climb also grants access to all other parts of the ship.

  • Fastest: The Cutty Sark Was The Fastest Ship Of Its Kind
  • Price For Climbing: Adult from £41 | Child (12-15) from £26
